Hello to all fans of tank battles and welcome to the site! Friends, today our guest is an interesting and unusual unit, an American medium tank of the fourth level, and this M3 Lee guide.
The most interesting and unusual nuance is that our American is deprived of a tower. Yes, yes, the main gun is located on the right side of the hull, and this superstructure is on the roof M3 Lee WOT serves to ensure that everyone shoots at her.
Nevertheless, anyone who decides to download the branch of American medium or heavy tanks will have to skate a certain number of battles on this miracle and should get to know him better.
TTX M3 Lee
First of all, each owner of this device should be aware that in his hands is a car with a small margin of safety and a weak base viewing radius of 320 meters by the standards of ST-4, which will need to be improved in the future.
You must also understand and always remember that American medium tank M3 Lee has very impressive dimensions, it is not only very tall, but also wide and, if I may say so, thick. All this makes the disguise very mediocre and only helps the enemies hit us.
The situation is even more aggravated when you look at what M3 Lee specifications booking. Most of the hull from the forehead is a huge sloping panel, which at its thickest point, taking into account the reduction, has only 83 millimeters of armor, and in general its thickness does not exceed 73 millimeters.
As you understand, punch M3 Lee World of Tanks almost all classmates will be able to, not to mention the technique of higher levels. It is also not worth hoping for the location of the gun, here the thickness of the armor is only 51 millimeters, and only closer to the edge due to the slope, this figure begins to increase significantly, but this area is very small.
There is nothing to say about the sides in our case, in a lateral projection M3 Lee tank even thinner, here the thickness of the armor plates does not exceed 38 millimeters, it can even be penetrated by machine guns.
Unfortunately, the American cannot boast of good driving performance either. Our maximum speed is not bad, but by the standards of medium tanks it is not high, the dynamics of M3 Lee WOT also mediocre and only the speed of rotation of the chassis pleases, in case of rapprochement with the enemy, we will have small chance fight back.
gun
Oddly enough, but this device and its creators can be proud of their weapons, despite some nuances, the gun at our disposal turned out to be really worthy of respect.
So, at M3 Lee gun it has good one-time damage by the standards of classmates and at the same time it has an excellent rate of fire, which allows us to deal approximately 2200 pure damage per minute, this is almost the best indicator among ST-4s.
In terms of penetration, we are also doing very well, M3 Lee tank WoT can even pierce most level 5 opponents without much difficulty. But as it often happens, for a comfortable battle at the bottom of the list, you will have to have 15-20 gold shells with you.
With accuracy, everything is not so simple, because the dispersion of our gun is large, the stabilization is poor and at the same time there is no rotating turret. However, it comes down medium tank M3 Lee quickly, so that the discomfort is not as strong as it might seem at first glance.
Now let's touch on the issue of comfort inflicting damage on the other hand, and here we must pay tribute to the good vertical aiming angles, after all, the barrel bends down by 9 degrees. But again I repeat, the towers M3 Lee World of Tanks no, the total UGN is 30 degrees and at the same time the gun is located on the right side of the hull, that is, in fact, in our hands is not a medium tank, but a tank destroyer.
Advantages and disadvantages
Although we have considered General characteristics tank and carried out an analysis of its weapons, in view of the fact that the vehicle in front of us is unusual, it would be reasonable to highlight the main advantages and disadvantages M3 Lee WOT separately.
Pros:
Good one-time damage;
Excellent rate of fire and DPM;
Decent penetration;
Fast mixing time;
Comfortable vertical aiming angles.
Minuses:
A truly shed silhouette;
Mediocre booking;
Weak mobility;
The absence of a tower;
UGN are uncomfortable due to the displaced gun.
Equipment for M3 Lee
So we got to the issue of completing the vehicle, and in view of the fact that in fact we have tank destroyers in our hands, the emphasis should be on armament. Of course, additional modules will allow you to improve some parameters well, so on M3 Lee tank equipment let's put the following:
1. is the most requested and reasonable module that will make our damage per minute even more dangerous.
2. - due to some problems with accuracy, this choice is quite justified, because the faster we converge, the more comfortable the shooting process will be.
3. - everything is obviously weak with the review, and this issue needs to be addressed radically, especially in view of the features of this device.
But for those for whom the viewing range and the possibility of the first shot are not so important, if you are not afraid to rely on allies, you can replace the last item with , get even more firepower and other things.
Crew training
Another great opportunity that should never be missed is the choice and distribution of skills among crew members. There are already six tankers in this car, and in order not to get confused, for M3 Lee perks it's better to distribute it like this:
Commander - , , , .
Gunner - , , , .
Gunner - , , , .
Driver mechanic - , , , .
Radio operator - , , , .
Loader - , , , .

Consumables also need to be given a little attention, but as you know, this aspect often remains standard. Our case is no exception, and in order to save money, you can buy a modest set of,,. But if you want to increase your survivability and get a chance to get out of a difficult situation, it’s better to carry on M3 Lee gear from , , , where the last option can be replaced by .
Tactics of the game on the M3 Lee
I repeat once again that due to the lack of a turret, it is rather not a medium tank in front of us, but a tank destroyer, respectively, the style of play should be chosen accordingly. It means that for M3 Lee tactics an ambush is more suitable for combat, after all, our armor is weak, and the silhouette is barn and mobility is mediocre.
So, at the very beginning of the battle, we choose a flank and occupy the most sprawling bush in the chosen direction. From such a position American tank M3 Lee can easily realize the potential of its weapons, while not greatly risking its own margin of safety.
Of course, you must provide cover and escape routes in case your M3 Lee tank WoT discover. For the rest, we just stand, shoot at our own and allied light, target vulnerable zones in the enemy’s armor, and if the enemy is armored in the sight, we charge the gold.
If you don't like this passive gameplay, M3 Lee World of Tanks still can play more contact, but it is important to take the position very correctly. The entire left side of the hull should be hidden, while only the part of the vehicle in which the gun is installed should stick out from behind the shelter. So we not only get a good opportunity for firing, but also make the area of contact with us minimal. Of course, between shots M3 Lee WOT should slightly turn the hull, increasing the angle of the reduced armor, or even hide.
The United States entered the First world war only at the very end of it, which gave them many different benefits. But the American military believed that the war would continue until 1919, and hence the logical conclusion followed that they would need tanks to win: both heavy breakthrough tanks and very light ones - "cavalry". The British Mk vehicles met the first requirement, while the French FT-17 light tanks met the second requirement. On their basis, American engineers (together with the British) developed and then released the Mk VIII tank - in fact, the crown of heavy tank building during the First World War, and then the very light and miniature two-seater tank "Ford M 1918", known in Russia as "Ford-3-ton". Both the one and the other designers created, taking into account both their own combat experience and the experience of the British and French. Knowing the capabilities of their industry, the Americans did not stand on ceremony: they immediately ordered 1,500 Mk VIII tanks, called "Liberti" (Freedom) or "International" (International), since this tank was created on two continents at once, and a whole armada of 15,000 Ford M tanks 1918". But by the time the armistice was signed, only one Mk VIII tank and only 15 Ford M 1918 vehicles had been made. After that, their production ceased, and why is clear.
Tank M3 by the late Vyacheslav Verevochkin. There lived such a man in Russia, at home, with his own hands he created tanks "on the go" and with the quality that you see in this photo. But… people on planet Earth, unfortunately, are dying. Although on the other hand, what remains is what was created by their hands.
General Rockenback made an attempt to reorganize the tank units of the US Army in such a way that they became an independent branch of the military. His proposals were supported by such combat commanders as George Patton, Sereno Brett and Dwight Eisenhower. But ... majors they are majors. Nobody listened to them then. Moreover, in 1920, the US Congress adopted an important document - the National Defense Act, according to which it was forbidden to create tank units as a separate branch of the military. Well, those tank units that already existed were transferred to the infantry.
Nevertheless, new machines were developed, built and tested. For example, in 1930, an experimental T2 tank appeared. With a weight of 15 tons, which corresponded to the assignment issued by the military, they put a powerful aircraft engine "Liberti" in 312 hp on it. This tank was armed as follows: 47 mm gun and heavy machine gun in the hull, and a 37-mm cannon and another rifle-caliber machine gun coaxial with it were installed in the turret. A feature of the tank was the engine in the front and the "door" in the hull at the back, like the British on the Vickers Medium Mk I tank, so it was very convenient to get into this tank.

Indeed, outwardly it was very similar to the English medium 12-ton Vickers Medium Mk I tank, and in fact it was chosen as a promising prototype of the future US medium tank. The completed tanks went to a mixed mechanized unit at Fort Eustis in Virginia. This experimental unit consisted of military vehicles, cavalry and powered artillery. Then another tank unit was created at Fort Knox in Kentucky. But all these experiments did not give real results.

Then the talented designer of armored vehicles John Walter Christie worked in the USA, an "eccentric" - as the American military called him, a man with all his talents, and maybe just because of them, very quarrelsome and extremely addicted. He offered the Ordnance Department a number of models of his wheeled-tracked tanks and self-propelled guns. Army officers, distinguished by their traditional incredulity, purchased only five tanks from him to participate in military trials, but after them his vehicles were rejected. Although Christie's designs in other countries have found their second life! His ideas were used in England, the USSR and Poland. As you know, it was in the USSR that about 10 thousand wheeled-tracked tanks of various modifications were produced, starting with the BT-2 and ending with the diesel BT-7M, which were based on the design of the Christie tanks. After all, even the legendary T-34 had its suspension. And it was used on all British cruiser tanks, including the Covenanter, Crusader, Sentor, Cromwell and Comet.

So, in a long search, the 30s passed. A whole family of medium tanks TK, T4, T5 and also their modifications were built, but none of these vehicles went into production.

This photo here gives a clear example of how crowded it was in this tank.
But then came September 1, 1939, and the tank wedges of the Wehrmacht for some 18 days went through Poland and met with the same tank wedges of the Red Army, which entered Western Ukraine and Belarus, on the other hand. And the further war in Europe, which ended with the swift defeat of the French army and the disaster at Dunkirk, clearly showed the United States that the war was on the verge, and that it would not be possible to sit out overseas. This means that the fight will have to be serious. And how can you fight without having modern tanks?

And then at once all the American military and senators saw the light and saw that their country was very far behind in the development of its tank forces. In fact, they simply do not exist. That's even how! And because the reaction to this followed very quickly. Already in July 1940, General George Marshall and General Staff ordered General Edn R. Chaffee to withdraw all armored units from the infantry and cavalry formations and to form two tank divisions at once, together with support battalions, as soon as possible. On June 30, 1940, the National Army Development Program was adopted, and already on July 10, General Chaffee began the formation of new armor tank units. All issued tanks came to him and no one else. To arm the new divisions, it was planned to produce 1000 tanks at once, while the production was to be 10 vehicles per day.

The M2A1 medium tank of the 1939 model was urgently adopted, which was an improved version of the M2 tank. The vehicle was designed by the Rock Island Arsenal and was a further development of the same experimental T5 tank. With a weight of 17.2 tons, the M2 had armor protection one inch (25.4 mm) thick, armed with a 37 mm M6 gun and seven (and another spare) 7.62 mm Browning M1919 A4 machine guns located along the entire perimeter of the hull, as well as in the tower. The "Wright Continental R-975" engine had nine cylinders and 350 horsepower, which gave the tank a speed of 26 mph (or 42 km/h). M2A1 received armor 32 mm thick - in fact, like German tanks, a larger turret and a 400 hp engine. The weight has increased, but the speed has remained the same. However, all these tricks did not lead to any particularly positive results: the tanks remained old-fashioned, had high straight sides and were not very well armed for vehicles of their class, since light M2 tanks with exactly the same 37 -mm cannon and sufficiently powerful machine-gun armament.
Medium tank M2. Interestingly, the tank had a crew of 7 people: a driver, gunner commander, loader and 4 machine gunners. Moreover, two tripods for machine guns were attached to the tank - to remove, install and fire from the ground, and there were two hatches on the roof of the sponson and two pins for machine guns and anti-aircraft fire! The tank had seven machine guns! A record number for a single-turret tank. Directly on the course, five could fire at the same time!
In June 1940, Lieutenant General William Nadsen, who created the General Motors Corporation, and K.T. Keller, the president of the Chrysler corporation, who concurrently led the national defense program, agreed that they would not produce the M2A1 at their enterprises, as this requires a complete restructuring of the entire production. They decided that they would earn much more on the production of cars for the army. They decided to transfer the order for tanks to two concerns: "American Locomotive company" and "Baldvin". But then, quite unexpectedly, Congress allocated for them production of 21 million dollars, including financing and construction of a new tank factory. Then K. T. Keller hastened to assure General Wesson, the chief of artillery of the US Army, that his corporation was ready to produce any tanks. It was agreed that 1741 tanks would be produced in 18 months. Thus, Chrysler received only 4.5 months to restructure its production and to submit a construction project dependent on other arsenal suppliers.
Then the situation was as follows: in Rock Island, two experimental M2A1 vehicles were built (which differed from the base model in slanted turret armor), and General Wesson allowed Chrysler engineers to study them, which was done. And not just done: the engineers did everything what was required so that their company could produce these tanks!Already on July 17, 1940, the M2A1 produced by the Chrysler concern was valued at 33.5 thousand dollars. The artillery committee accepted this price as "floating". Then, within a month, the contract was carefully worked out and already signed on August 15. The company was supposed to hand over 1000 M2A1 tanks to the US Army by the beginning of August 1940, and their production was to begin no later than September of the following 1941. This period was designated by the Chrysler concern itself, considering one month to be quite a sufficient period to prepare for the release of new products.
First, Chrysler made two wooden mock-ups of the M2A1 from blueprints that were obtained from Rock Island. But already on August 28, 1940, the army canceled the old order for 1000 M2A1 tanks, despite the fact that 18 units still managed to be made. Some of these tanks were sent ... to Western Sahara. It was not possible to find information about their participation in hostilities. It is known that in 1941 one of the tanks received a flamethrower instead of a gun, and a tank with a combustible mixture was installed on it in the stern. The car was assigned the M2E2 index, but it remained a prototype.

At that time, the discussion about the possibility of arming the M2A1 tank with a 75-mm cannon ended (which, by the way, was already provided for in the project of the T5E2 tank), and according to its results, a completely new and "unscheduled" tank was created. The Aberdeen Proving Ground Design Department prepared all the necessary project documentation in just three months. The tank was given the designation M3 and a proper name - "General Lee", in honor of General Robert Edward Lee (1807-1870), who during the Civil War of the North and South of 1861-1865. in the United States he was the commander-in-chief of the army of the southerners.

The creators of the M3 tank put a 75-mm gun in the side sponson on the right side of the hull, like on the French Schneider tank of the First World War. This was the simplest solution, since the installation was like ship guns, the machines for which were well developed. In addition, the 76-mm gun installed in the tank was very powerful, and the designers were not sure whether it would work well in the turret. This showed a certain amount of uncertainty on the part of American designers in their own strengths, but in addition, they also showed their unwillingness to abandon their usual views on tanks as mobile pillboxes that were supposed to fire while standing still. A cast rotating turret was installed at the top, moving it to the left, and a 37-mm gun was installed in it, paired with a machine gun. The small turret on top also received a machine gun, which the tank commander could use both for self-defense against infantry and for firing at aircraft.
(To be continued…)
Official designation: M3 medium tank
Alternative designation: “General Grant”, “General Lee”
Start of design: 1940
Date of construction of the first prototype: 1941
Stage of completion: mass-produced in 1941-1943.
As you know, there are no more permanent solutions than temporary ones, and the American M3 tank, known to us under the names “Grant” and “Lee”, confirmed this theory by 100%. But at first it was planned that the M3 would be produced only before the appearance of the M4 tank ...
May 1940 brought bad news from Europe. It turned out that the Allies seriously underestimated the power of the Wehrmacht. But most importantly, the German tanks Pz.III and Pz.IV turned out to be stronger than the British "cruisers" and most French tanks, with the exception of SOMUA S-35 and Renault B-1bis. Against this background, the presence in the US tank corps of tanks armed only with a 37-mm cannon and machine guns looked like an obvious anachronism. Paradoxically, the most powerful American vehicle turned out to be the Medium Tank M2 with just such a composition of weapons, and it became obsolete literally after it was put into service.
The Americans were not going to put up with this fact, and already on June 5, 1940, the commander of the infantry of the US Army sent a request to the Department of Armaments to install guns with a caliber of at least 75 mm on all medium tanks. Fortunately, the officials reacted immediately - already on June 13, the tactical and technical requirements for the new tank were determined, and on July 11, the preliminary draft was approved under the official designation Medium Tank M3. The Americans were in a hurry, because the war approached the borders of Great Britain, and France suddenly became an ally of Germany. So, the manufacture of individual components and assemblies of future M3 tanks began in advance. In fairness, it should be noted that the M3 medium tank did not differ much from the M2. In fact, the calculation was made precisely for this, and the main differences between these two machines were only the armament and its layout.
The main requirement put forward by the Ordnance Department was the installation of a 75 mm gun. Here the Americans faced two big problems: the complete absence of a tank artillery system of a suitable caliber and the impossibility of placing existing suitable guns in the small turret of the M2 tank. In this situation, I had to go to various "tricks", which later cost the tankers of the countries of the anti-Hitler coalition dearly.
The 75-mm T7 gun with a barrel length of 2134 mm was chosen as the main one, which was a modified version of the T6 gun, adapted for firing unitary shots from a 1897 model gun. This old French-style artillery system turned out to be very reliable and at one time served as a prototype not only for American field guns, but also for the Russian “three-inch gun”. After the next modernization, which consisted in the installation of a semi-automatic shutter, the gun received the designation M2, and the gun mantlet began to be designated as M1. Preliminary tests were carried out on a prototype medium tank T5E2, mounting the gun in a sponson on the right side. The experience was considered successful and the same installation option was used on the M3. This decision significantly increased firepower tank, but the American engineers could not provide the optimal sector of fire. On the horizon, aiming the guns could only be carried out manually and within 15 ° in both directions. In addition, the tank artillery system turned out to be unbalanced in terms of mass distribution, as a result of which a counterweight had to be attached to the barrel, sometimes mistaken for a muzzle brake.
Partially, this design flaw was corrected in the next modification of the gun under the M3 index. The barrel length was increased to 2810 mm, which made it possible not only to increase the muzzle velocity of the projectile from 564 m/s to 610 m/s, but also to abandon the counterweight. However, the production of M3 guns, which were planned to be installed on T6 tanks (the future M4 “Sherman”), was limited and most of the medium tanks of the M3A1 series received M2 guns.
In fairness, it should be noted that in the current situation, the installation of the “main caliber” in the sponson had certain grounds and had previously been tested on tanks of other countries. In 1918, the British considered projects with the installation of 57-mm guns in "diamond-shaped" tanks, but in the end they preferred the lighter Vickers Medium Mk.I, only in 1940 returning to this topic again for one reason only - at that time the main the tank gun was a 2-pounder (40-mm) cannon with a low explosive action of the projectile, although some of the tanks were assembled in the "artillery" version and equipped with a 94-mm short-barreled howitzer with low armor-piercing qualities. Here is such a specificity.
The French did it even easier. From the very beginning of the creation of an infantry support tank, which resulted in the appearance of the Char B1 from Renault, the presence of a 75-mm cannon in the frontal hull plate was a prerequisite. And then no one was embarrassed by the extremely narrow sector of fire on the horizon. Why they did it this way - yes, because in the concept of French strategists, all the main goals should have been just ahead of the course.
Such “hybrid” weapon installation schemes were practiced at that time, and the 75-mm cannon in the sponson of an American tank does not look like such a “savagery” or “design miscalculation”, as they are trying to present now.
The next round of meetings between representatives of the army and officials took place in mid-August 1940 at the Aberdeen tank training ground. This time, the requirements for a medium tank were clarified - the parties agreed that the M3 would be used chassis medium tank M2 with a new hull and a new composition of weapons. The installation of the 75 mm gun was coordinated in the side sponson on the right side of the front of the hull, and the 37 mm gun and the 7.62 mm Browning machine gun coaxial with it were to be installed in the turret. The rotation of the turret together with the gun could be carried out in two ways: manually and using a hydraulic system.
Thus, the “distribution of duties” was carried out: a large-caliber gun had to deal with field fortifications, and a turret gun was well suited for destroying light armored vehicles. But in any case, the M3 tank was then considered as a transitional model from the M2 to the M4. In fact, the release of "triples" continued until 1943.
The approval of the M3 tank project coincided with the reorganization of the US armored forces, during which the Tank Corps became the Tank Forces and on August 26, a model of a new combat vehicle was presented to representatives of the specially created Tank Committee. According to the final specification, in addition to two guns, a commander's cupola with a 7.62 mm Browning machine gun was mounted on the main turret. Reservation of the frontal part of the hull was 50.8 mm, sides - 38.1 mm. Machine-gun sponson mounts, inherent only to the M2, were absent, and only pistol loopholes remained in their place. The volume of fuel tanks was also increased, the radio station was installed in the left sponson, the crew seats became more comfortable and received seat belts.
Two days later, on August 28, 1940, a contract was signed for the supply of 1000 M3 tanks instead of the same number of M2A1 tanks. The Ordnance Department gave only 60 days to complete the design work - during this time it was necessary to produce about 10,000 working drawings, so the Detroit Tank Arsenal faced a non-trivial task. Despite the fact that the plant in Detroit was reconstructed, in September it was possible to start manufacturing individual units according to preliminary sketches, fortunately, the structural similarity with the M2A1 made it possible to do this without any problems.
The assembly of the first prototype began in Rock Island, as drawings and details arrived. In parallel, the tank turret was made and sent to Aberdeen, where it was equipped with a mask and a gun. Preliminary tests were carried out on the M2 tank, and the first demonstration of the “modernized” vehicle to representatives of the Department of Armaments took place on December 20, 1940 and was very successful. Nevertheless, the engineers failed to meet the 60 days allotted by the Department, although, by American standards, the creation of the M3 tank passed an extremely short time. Preliminary design work was completed only by February 1, 194, and on March 13, the first prototype was completed, so far without a turret. On the same day, test drives were carried out at the Rock Island Arsenal and on March 21 the tank was sent to Aberdeen. There, a tower with a commander's cupola was installed on the prototype, which had only one observation slot on the right side, and preliminary tests were carried out. During April, a batch of pre-production vehicles was delivered, and only on May 5 did the first production tank arrive in Aberdeen.
It just so happened that the production of M3 tanks was ahead of the supply of guns to them. Not only long-barreled M3s, but also M2s were lacking, and most of the production vehicles of the first series were operated without them as training ones. True, this only had to do with the tanks that remained in the United States. Products for export went with a full complement of weapons and equipment.
As mentioned earlier, the undercarriage of the M3 medium tank was borrowed with minor modifications from the M2A1 tank of the same class. On each side there were three bogies with spring-loaded track rollers. Structurally, the cart consisted of the following components: two rubber-coated track rollers were suspended on a pendulum with the help of strained horizontal helical springs protected by an armored casing. A roller supporting the upper branch of the caterpillar was mounted on the top of the bogie. the trolley assembly was attached to the lower side armor plate of the hull with bolts. The caterpillar was assembled from steel tracks with rubber inserts, which had a width of 406 mm.
The latest series were equipped with a 421 mm wide track and a new type of support roller installation. Now it was mounted on a bracket moved back, and a skid appeared in its place.
The first version of the hull, used for the production of M3 tanks, had a riveted design and layout with a front transmission, a middle location of the fighting compartment and an engine compartment in the aft.
The shape of the hull turned out to be very exotic, which, however, was not surprising - the Americans once again tried to combine business with pleasure - that is, to ensure comfortable work for the crew with high firepower.
The most unusual was the bow of the hull, assembled from three armor plates 50.8 mm thick, which had a double angle of inclination. In the upper part of the frontal armor plate, a cutout was made for the hatch, which was closed by an armored cover with a viewing slot protected by bulletproof glass. The second hatch, but smaller, was made on the left side. The rear side armor plates of the superstructure, 35.8 mm thick, were beveled towards the longitudinal axis of the hull and connected to the transverse armor plate. The sides and stern armor plates of the same thickness were strictly vertical, but the upper stern plate received a slight angle of inclination. On top of it were attached two boxes with spare parts and tools. The roof of the superstructure with a thickness of 20 mm was installed horizontally. The lower evacuation hatch was missing, since it was concluded that it would be more convenient for the crew to leave the wrecked vehicle through the hatch on the starboard side of the hull. As it turned out later, this decision was not justified.
In general, the picture was favorable, with the exception of a couple of "nuances". First of all (and this was very striking) the tank had a huge height of 3.12 meters. To understand whether this is a lot or a little for a medium tank of the early 1940s, we can compare the Soviet "monsters". For example, the height of the five-turret T-35A tank was 3.34 m, the three-turret T-28 - 2.17 m, and the two-turret SMK and T-100 - 3.15 and 3.41 m, respectively. So in terms of camouflage and low ground, the crews of the "grants" were guaranteed problems.
But that was not all - counting on the M3 tank as a temporary measure, the Americans decided to simplify their lives to the maximum. Almost all armor plates were assembled using bolts and rivets. How this turned out for many tankers, primarily those who served the “lower floor”, was revealed in 1942, when the M3 entered the African front and experienced the effect of armor-piercing shells of the German and Italian anti-tank guns. When a “blank” hit, quite often all these “cogs” were completely torn out and, in fact, turning into secondary fragments, severely crippled the crew.
The layout of the crew seats, taking into account the layout of weapons, was originally designed for 7 people. The driver's seat was located in the left front of the hull. At the level of the head there was a viewing slot protected by armored glass, below there was a dashboard, which included: a speedometer, a tachometer, an ammeter, a voltmeter, an oil pressure gauge, an engine temperature gauge and a clock. The controls consisted of two steering levers, a gearshift lever, a handbrake, and gas and clutch pedals. Two 7.62-mm Browning course machine guns were rigidly attached in front of the driver. Later, one of the machine guns was dismantled, closing the hole under it with an armored plug. The stowage carried an 11.43 mm Thompson submachine gun. After the release of the first series of tanks, they demanded to remove it, but then this decision was considered erroneous. On the right side of the front of the hull, behind the gun, there were gunner's seats (slightly behind the driver's seat) and loader (to the right of the gun lock). Directly, the 75-mm gun (of any variant) in the M1 mask was equipped with a gyro-scoring stabilizer in the vertical plane.
The main part of the fighting compartment, where the tower was installed, was also designed for three people. The commander was located in the center behind the 37 mm gun and served the 7.62 mm machine gun in the commander's cupola. To the left of the gun lock was the gunner's place, to the right - the loader. The maximum elevation angle of the 37-mm gun was +60°, the minimum -7°, which theoretically made it possible to conduct barrage fire on air targets. During testing of prototypes of the M3, it turned out that the M6 gun was also unbalanced and had to be balanced using a metal cylinder attached under the barrel.
However, very soon it was concluded that there would not be enough space in the tank for seven, and the duties of a radio operator were transferred to the driver. By and large, this step turned out to be quite justified.
The means of communication consisted of a VHF radio station SCR 508, which was located to the left of the driver's seat, and an internal intercom (intercom) of the Tannoy type. The external communication antenna was installed on the right side on the beveled rear armor plate of the hull superstructure. The SCR 506 radio station could be installed on command tanks, but the vehicles of the early production series were partially equipped with the SCR 245.
A radial engine was installed in the stern of the hull aviation type Wright R-985EC2 rated at 340 hp, equipped with an air-cooled system. Torque from the power plant was transmitted using a drive shaft and a multi-plate dry clutch, which passed through the fighting compartment to the transmission. Then the torque was transmitted to the steering differential and then to the final drives and drive wheels located in front.
When the M3 tank was just being launched into mass production, Wright was already overloaded with orders, including for export deliveries. In order not to slow down the pace of tank production, the production of R-985EC2 engines had to be placed at the Continental Motors plant.
Electricity was generated by an auxiliary generator with a current strength of 50A and a voltage of 30V, driven by a two-stroke single-cylinder gasoline engine. The current was supplied to the lamps of internal and external lighting.
M3 tanks of all modifications, made in the USA, did not have a single standard color. Depending on the series and year of issue, they could be painted in green in various shades (from dark green to khaki). Later, from about 1943, due to combat experience, it was recommended to apply camouflage color patches, but all American tanks that took part in the hostilities retained standard camouflage, with rare exceptions.
The registration number assigned to each tank by the Department of Ordnance was applied in different colors on the side plate in the engine area on both sides: the name of the USA country is blue, the code W is blue, the six-digit number is white or yellow.
The insignia of the American armed forces was applied to the turret and the front plate of the hull - a white star in a blue circle superimposed on a white stripe. However, this rule was not always observed. Some of the tanks received stars without circles or stars and stripes around the perimeter of the yellow turret.
Also, tactical designations were applied to the turret and hull with white paint: the serial number of the vehicle in the company was the first, followed by the letter designation of the company (for example, 9E or 4B), but in some cases a simple number without a letter was assigned. At the beginning of the war, geometric figures were drawn on the sponson, on the port side next to the door, indicating the number of the company, battalion and regiment in the division. However, since 1942 they also almost completely disappeared. The distinctive signs of the division were applied on the middle sheet of the transmission.
On the tanks that fought in North Africa, instead of a star, the American star-striped flag was on the frontal armor. However, it soon became clear that this unmasks the car, and since 1943 they have almost completely disappeared.
As mentioned earlier, the first serial modification was the M3, the construction of which began in April 1941 at the enterprises of the Detroit Arsenal (Detroit Tank Arsenal), American Locomotive Company and Baldwin Locomotive Works. Further, with the growth in serial production, the number of assembly shops only increased - in July, Pressed Steel Car Company took over the assembly of M3 tanks, and in August Pullman Standard Car Company joined it. By this time, production had been brought to a predetermined level, and the delivery of tanks was now carried out without delay.
The first modification was in serial production for a relatively short period and ended in March-August 1942, but during this time 4924 M3 tanks were built. By enterprises, they were distributed as follows: Detroit Arsenal - 3243 (until August), Pressed Steel - 501 (until March), Pullman - 500 (until March), American Locomotive - 385 (until August) and Baldwin Locomotive - 295 (until March) . As a result, the very first modification was also the most massive.
The sad experience of meeting with anti-tank artillery and armor-piercing shells of tank guns led the Americans to disappointing results. If frontal armor plates did not break through very often (as a rule, if anti-tank guns with a caliber of more than 37 mm were not fired from distances of less than 500 meters), then the mantlet of a 75 mm gun and the sides were struck very confidently. There were still small reserves for increasing armor, but in this case, the load on the suspension increased even more, and in this case it could simply not withstand. The mobility of the tank also decreased, but the main drawback was that when a large projectile hit, the rivets could not withstand and the crew was literally bombarded with secondary fragments of armor and bolts. A way out of this situation was found fairly quickly.
In general, I saw two options - to make the body welded or cast. For new version М3А1 the second path was chosen, since American metallurgists gained enough experience in the production of cast towers. In fact, only the upper part of the hull, covering the transmission, the control compartment and the front of the combat compartment, had to be cast. The shelling tests of the first castings gave very encouraging results, and on October 9, 1941, the Armaments Committee approved a plan for the production of M3A1 tanks with a cast hull.
Externally, the new modification differed from the M3 in the smoother outlines of the hatches on the upper part of the fighting compartment and along the sides. On the cast hull, the upper hatch was shifted with an inclination to the stern and deployed 45 °; On the first M3A1 tanks, hatch hinges were placed on the side of the turret, but all subsequent vehicles received hinges on the opposite side. They also abandoned the pistol loopholes in the rear wall of the superstructure and removed the side door, which was often torn off by a direct hit by a projectile. Of the other improvements, it is worth noting the introduction of three fans of the fighting compartment, as on the M4 Sherman tanks. On later M3A1 tanks, side escape hatches were also abandoned, which made it possible to increase the projectile resistance of the hull.
The production of M3A1 tanks was launched at the American Locomotive Company, where 272 vehicles were assembled from February to August 1942. As an alternative power plant, due to a shortage of Wright gasoline engines, a Guiberson T-1400-2 diesel installation was tested. In general, the tests of the diesel M3A1 were successful, although the Giberson turned out to be very capricious in operation. The Arms Committee considered it necessary to recommend the T-1400-2 for installation on all M3 series tanks, but only 28 vehicles received the diesel engine, which received the name M3A1 (Diesel). However, the main reason for the cessation of production was the cast body - for all its advantages, it turned out to be difficult to manufacture. The cast structure was to be replaced by a simpler welded one, which was done on the M3A2 modification.
The new hull was developed by engineers at the Rock Island Arsenal almost in parallel with the production of cast turrets. In shape and configuration, it practically did not differ from the M3 modification, but welding made it possible to significantly increase manufacturability and reduce the cost of manufacturing hulls. Release of tanks of the series M3A2 lasted at the Baldwin Locomotive company for only four months - from January to March 1942, and ended with the assembly of ... a total of 12 cars. They were replaced almost immediately by a new modification of the M3A3, which had the same body, but with a new power plant.
This time we again decided to return to experiments with diesel engines. The fact is that in addition to certain advantages over gasoline engines (a low-speed diesel made it possible to achieve better cross-country ability with an increased power reserve), there was another subtle nuance. When the M3 tank was created, its designers did not expect that Continental radial engines would be in demand in such large quantities for primary needs - that is, for the aviation industry. For tanks, they became sorely lacking, and in August 1841 it was proposed to use a completely new type of diesel engine on the M3 series machines.
Since the experiments with the Gibersons ended with only partial success, a specific power plant was developed for the medium tank. In fact, the new General Motors 6046 engine was a pair of two 6-71 automobile diesel engines (in-line, two-stroke), located in parallel and connected into one common unit. At the same time, each of the engines retained autonomous fuel, lubrication, cooling and start-up systems. Accordingly, the transmission had to be redesigned. Now it consisted of two single-disk dry friction clutches, a transverse connecting gear, a cardan shaft, a gearbox, a turning mechanism and final drives.
Due to the increased dimensions of the power plant, the length of the engine compartment had to be extended by 300 mm, and this refinement was carried out by reducing the volume of the fighting compartment. The design of the aft hull has also undergone changes. In particular, an armored box of the exhaust air channel was installed at the level of the tracks, where the reflector of the exhaust gases and the air that cooled the engine was located. The vertical aft armor plate was tilted by 10 °, removing the technological hatch doors in it. At the same time, wide double-leaf armored blinds were placed above the engine.
Thanks to the higher efficiency of the diesel, the fuel capacity has been reduced to 652 liters, while the range on the highway has increased to 240 km. A small negative point was an increase in combat weight by 1 ton, but in total this did not play a big role.
The first sample of the M3 tank with a GM 6046 diesel engine was manufactured by the Detroit Arsenal and delivered to the Aberdeen Proving Ground in the early autumn of 1941. The Military Commission, having evaluated the test results, in October approved plans to build a new modification of the tank. Production was again launched at the Baldwin Locomotive company, where the new tank began to be produced under the designation M3A3 - a total of 322 vehicles were assembled.
Shortly thereafter, the design of the tank underwent a regression - the riveted hull, so successfully used on M3A3, was again replaced with a riveted one. This, partly forced step, was the result of increased orders not only from the US Army, but also from the allies. Tanks were required to be delivered to the UK, the USSR, Australia and New Zealand, so the total bill in the contracts went to thousands of vehicles. Give a plan with simultaneous transition in 1941, the Americans could not use the welded hull structure, and in such a difficult situation, it was decided to continue the production of tanks of the M3A3 series, but with a riveted hull. Such a “regression” variant was designated M3A5 and was produced from January to December 1942, becoming the second mass modification after the M3 - a total of 592 tanks were built.
After installing the GM 6046 diesel engine, experiments with the power plant did not end. An inspection conducted at the Chrysler plant by representatives of the military department in June 1941 was forced to state that there were still not enough tank engines. Then William S. Nadsen (who was a member of the National Defense Advisory Commission, which was responsible for coordinating the work of the American defense industry) proposed to create an alternative version of the power plant, based on existing developments.
At the end of 1941, Chrysler introduced a unique power unit under the A57 Multibank index. This design consisted of five 6-cylinder automobile engines connected in a star shape. The power of this power plant was only 370 hp, but in the absence of more profitable options, the A57 was accepted for production and installed on tanks M3A4. As you might guess, the new modification was a continuation of the M3A2-M3A3 line, differing from it only in the hull length increased to 6147 mm. Such an “improvement” was the result of the increased dimensions of the engine, due to which the engine compartment “grew” by 280 mm and the stern of the tank received an overhang 381 mm long. Other features include two convex roofs of the engine compartment: the lower one protected the fan, and the upper one covered the cooling system units. In addition, two fuel tanks had to be removed from the engine compartment. Instead, two additional fuel tanks of 352 liters each were installed outside.
The changes also affected the chassis. Since the center of mass has shifted, the middle and rear bogies have been moved 150 mm back. Accordingly, the length of each caterpillar branch has increased from 79 to 83 tracks. The support wheels were now mounted on brackets attached to the top of the track roller bogies, and were moved back a little.
The production of tanks of the M3A4 modification continued from the end of June to August 1942 at the Detroit Arsenal. A total of 109 vehicles were built, after which the company was reoriented to the production of M4A4 Sherman tanks, also equipped with A57 engines.
The mass appearance of the M3 tanks happened just at the moment when the production of medium tanks T-34 and heavy KV-1 was in full swing in the Soviet Union. Armed with 76.2 mm guns, these vehicles turned out to be very dangerous opponents for the Panzerwaffe, so it was somewhat strange that in the UK they continued to "stamp" cruiser tanks of the A15 type, equipped with only a 40 mm gun and protected by 30 mm armor, by the hundreds. The bitter experience of the battles in Greece and France made British designers think hard, but while they were thinking about further trends in the development of their own armored vehicles, the Crusader, A9, A10, and even more so the Light Tank Mk.VI, were outdated by the middle of 1941.
In this situation, there was only one conclusion - it was necessary to look for a reliable ally capable of providing thousands of tanks and armored vehicles in the shortest possible time. And such allies were then the United States. Initially, the British tried to persuade local manufacturers to expand the production of their own equipment, such as "Matilda" II or "Valentine", but the Americans responded with a categorical refusal, citing a lack of capacity. Actually there were two reasons. The first has already been voiced and I am only partially true - another unpleasant moment for the British was their unenviable position on all fronts. The only success was achieved only in North Africa, and even then, until Rommel appeared there. In the rest of the theater, including even Somalia, the troops of the British Commonwealth suffered, if not a complete fiasco, then at least a significant defeat. Based on this, the UK had no choice but to agree to the purchase of American tanks. The British Purchasing Commission, which included front-line officers, looked at the events with more sober eyes than their American counterparts, and therefore the choice turned out to be very small - the medium M3 became the first tank that was supposed to go to fight on the side of the British Commonwealth.
After evaluating the capabilities of the machine, the British came to the conclusion that North Africa would become the main theater of operations for it, where a major offensive was planned for 1941. The allied tank program at the beginning of the same year provided for the production of 1000 medium tanks monthly, but already in June the plan for 1942 was 2000 tanks. This is not counting supplies for the US Army. At the same time, the opinion of the commission about the M3 was not so rosy.
Now they are trying to present the receipt of the M3 tanks by the Royal Tank Corps as an undoubted happiness - the main argument in this matter is the superiority of the American vehicle over the British "cruisers" in terms of armor and weapons. However, not all British tankers shared this opinion during the war years.
In terms of booking, the “American” was, of course, one of the most “thick-skinned”, but in terms of overall security, any of the M3s was inferior to the Matilda II infantry tank, also differing in the worst side with its huge dimensions. The only advantages of the M3 were the presence of a more powerful cannon armament and a spacious fighting compartment. At the same time, the installation of a 76.2-mm gun in the side sponson could hardly be called a good solution. On the other hand, the American 37 mm tank gun was slightly weaker than the British 2-pounder (40 mm) tank gun.
The A22 “Churchill” Mk.I infantry tank that appeared next (which was more of a heavy class tank) overtook the M3 in almost all respects, including dimensions, but in terms of total muzzle power, the advantage still remained with the M3. In addition, in 1940-1941. tested hard TOG tank, whose armament initially tried to include a 75-mm cannon in the frontal hull plate and two 40-mm cannons in sponsons. Reservation of the frontal and side surfaces was 62 mm. Even taking into account the transfer of the 40 mm gun to the turret and the elimination of the sponsons, the TOG looked more powerful than the M3. Another thing is that the “American” is usually compared with cruising-class tanks (A9, A10, A13 and A15), which he outplayed in all respects, with the exception of speed and mobility. In general, the attitude of the British to the M3 was twofold and there were some improvements.
There was simply no time for a radical change in the design of the tank. The Americans received a requirement to develop a new elongated cast turret, in the niche of which a British-style radio station No. 19 was installed. Closer to the rear, viewing devices were placed (one from each side) and loopholes for firing from personal weapons. The commander's turret was absent as unnecessary, and its place was taken by a low superstructure with a double-leaf hatch, behind which they made an outlet for the antenna. In total, this made it possible to reduce the height of the tower by about 30 mm and, accordingly, reduce the visibility of the tank. Actually, the improvements were completed on this. Modification of the M3 tank for the UK received its own name "Grant" I, in honor of the American General W.S. Grant, who commanded the northerners during the Civil War. The first contracts with Baldwin, Lima and Pullman were signed at the end of 1940, and deliveries of serial products began six months later.
Since 1942, tanks began to be produced for the UK Grant II, which were M3A5s with American-style turrets and minor changes in equipment. Somewhat earlier, in June 1941, the lend-lease law came into force and the British had the opportunity to almost double the number of tanks supplied. This time, an agreement was signed on the supply of standard M3 tanks, called "Lee" I. Subtle British humor was reflected here, as General R.E. Lee once commanded the troops of the southerners (remember the history of the Cromwell and Cavalier tanks) ).
British M3 tanks initially had a "native" color and in this form most of the vehicles that arrived in 1942 were used in battles in Libya and Egypt - there was simply no time left for repainting. Subsequently, by the forces of the crews and repairmen themselves, the tanks tried to completely paint them in sand-colored desert camouflage as soon as possible, or at least apply stripes. The registration numbers were retained, but the letter W was replaced by a T. A standard British cockade of vertical red-white-red stripes was applied on board the hull, although not all British M3s had them.
As a rule, a contour of a geometric figure with a number inside was drawn on the tank turret. The figure: a square, a circle or a triangle, denoted the number of the tank squadron, and the number - the serial number of the vehicle in the squadron. The color of the contour and the number was determined arbitrarily. The division and brigade markings were red eight and a half (216 mm) - nine and a half inches (240 mm) squares with a white number inside and were applied on the front of the left wing and the rear of the right or on the armor cover of the transmission. Emblems of brigades and divisions could be drawn on opposite wings.
A little non-standard for the British army, the tanks that fought in Burma were painted. These vehicles were painted green with large white stars on the hull and turret. Almost all tanks retained registration numbers. Some of them also had individual numbers on the frontal armor, and their own names on the sides (for example, "Cossack").
During 1941-1942. The British Army received 2887 M3 tanks of four variants, which exceeded their total number that entered service with the United States. Only "Grant" Mk.I was delivered 1685 units. Other variants of the M3 received the following British designations and were delivered in smaller quantities: M3 - "Lee" Mk.I(968), M3A1 - "Lee" Mk.II, M3A2 - "Lee" Mk.III, M3A4 - "Lee" Mk.IV(49), M3A5 - "Grant" Mk.II (185).
In addition, after the arrival of more modern M4 Sherman tanks, some of the tanks were converted into various kinds of auxiliary vehicles;
"Grant" ARV- the conversion of the tanks "Grant" I and II in the BREM, carried out in 1943. On all machines, weapons were dismantled, in place of which repair equipment and a winch mechanism were installed. There were two versions of the ARV - without a turret (the niche was welded and a hatch cut out in it) with an anti-aircraft machine gun and with a dummy turret (only a few tanks were redone).
"Grant Command"- modification with dismantled weapons (only a turret with a model of a 37-mm gun was left) and an additional radio station in the hull. The car was intended for use by senior officers.
Grant Scorpion III- modification of the mine trawl percussion series "Scorpion". A massive frame was mounted in front of the hull, on which a rotating drum with chains was installed. At the same time, the 75-mm gun was removed, and the counterweight was loaded aft. Several examples have been built.
Grant Scorpion IV– further development of the previous model. The main difference was the installation of an additional Bedford engine at the rear of the tank, the power of which was used to rotate the drum.
"Grant" CDL- one of the most original modifications of the Grant tank, work on which began back in 1941. The idea was to blind the enemy with beams of powerful searchlights in a night battle. The first experiments were carried out on infantry tanks "Matilda" II, one unit of which was sent to the Middle East at the beginning of 1942, but then there was not enough determination to use them in battles. The appearance of the M3 tanks brought the CDL project to a new level. Improvements were reduced to the installation of a fixed cabin instead of a tower where a searchlight was installed. At the same time, the 75-mm cannon in the side sponson and the bow 7.62-mm machine gun were preserved. Later production vehicles also received a fake 37 mm cannon in the wheelhouse.
Grant CDL tanks were sent in 1943 to the 1st Tank Brigade, but since the war in Africa ended in battles, they did not have time to use them. The tanks were sent to Europe, but even here the CDL remained unemployed for more than a year. Only in the spring of 1945 did several vehicles take part in the night crossing of the Rhine and Elbe rivers.
The “temporary measure”, as expected, turned out to be not so temporary - the M3 tanks served almost until the end of the war due to their technological design and ease of maintenance. Last but not least, this happened thanks to a successful running gear, which, with minor changes, moved from the M2, first to the M3, and then to the M4. Therefore, it is not surprising that the "li" became a kind of "ancestor" of several types of self-propelled guns and armored vehicles for special purposes at once.
Primary attention, of course, was given to self-propelled guns. The experience of fighting in France and North Africa turned out to be simply invaluable, and the Americans briskly undertook to catch up. Most of these self-propelled guns are quite worthy of a separate story, therefore, in the framework of the article about the M3 tank and its modifications, we will limit ourselves to a general description of these vehicles.
M12- one of the first proposals for the development of a heavy self-propelled guns appeared in June 1941 and did not meet with much interest from the side of the "gunners". The proposal was to install on the chassis of the M3 tank a 155-mm T6 gun from the times of the 1st World War, which had long been gathering dust in warehouses. Although such a move promised considerable advantages and the prototype, released in February 1942, successfully passed the tests, the military reacted coolly to it. Despite the fact that between September 1942 and March 1943, the assembly of 100 M12 units was launched by the efforts of the Pressed Steel Car Company, things progressed very slowly. Only in December 1943, before the planned landing in France, did the Americans “suddenly” remember that they had a really effective means to deal with long-term German fortifications. In total, having transferred the order to Baldwin, they assembled 74 self-propelled guns and the same number of M30 transporters.
T6- a variant of a self-propelled gun with the installation of a 105-mm gun on an open platform. One prototype built.
T24- a variant of the 76.2-mm self-propelled gun developed in the fall of 1941. The goal of the project was to obtain an anti-tank self-propelled gun, however, the installation of the gun in the wheelhouse open from above turned out to be unsuccessful and in 1942 work on it was stopped. One prototype built.
T26- the only prototype of a 75-mm self-propelled gun.
T32 \ M7 "Priest"- In October 1941, Major General Jacob Devers (Jacob Devers), anticipating the need to have mobile heavy artillery, ordered the Arsenal in Rock Island to manufacture a prototype self-propelled 105-mm howitzer. An embrasure was cut in the frontal sheet of the cabin to install the gun barrel. A carriage was mounted in the hull, on the starboard side - a turret with a 12.7-mm anti-aircraft machine gun. The crew consisted of 6 people. The initiative was supported and in February 1942 two prototypes were tested. The results were encouraging - the self-propelled gun showed a maximum speed of 40 km / h, a cruising range on the highway - 210 km, on the ground - 140 km. This made it possible to launch mass production of self-propelled guns already in April, when she received an index M7 and title Priest. A total of 4267 cars were produced. In parallel, a similar project was developed in the UK with the installation of a 25-pounder gun, which later became known as Sexton.
T36- the only version of the self-propelled anti-aircraft installation on the M3 chassis. The project, proposed in the fall of 1941 by the Air Defense Committee, provided for the installation of one 40-mm anti-aircraft machine gun in an original turret. Work was stopped in 1942 due to the high complexity of the design. One prototype built.
T40 \ M9- the first version of the self-propelled guns on the M3 chassis, built in series. The project was drawn up at the end of 1941 and assumed that by installing outdated 76.2-mm anti-aircraft guns of the 1918 model on a tank chassis, it would be possible to get a full-fledged anti-tank self-propelled gun. The idea turned out to be rational and even an order for 50 vehicles was issued, but already during the tests it became clear that the T35 project (future M10) has more prospects. However, in 1942, 28 self-propelled guns were built under the designation M9, which were used to a limited extent inside the United States.
Now let's move on to special-purpose armored vehicles. Far from being of secondary importance was attached to this topic in the USA, since the success of many operations depended on good supplies. However, other options were also not forgotten.
T1– a self-propelled trawl equipped with a double disc roller mounted in front and one roller at the rear. Initially, this version of the trawl was intended for the M2A1 tank, but after the appearance of the M3, the priorities changed. The tests were held with varying success, and in the end it was concluded that the disk trawl of this design was unsuccessful.
T16- the first version of the artillery tractor, which appeared in 1942. The turret was removed from the standard M3A5 tank and a winch was installed at the stern. The tests of the T16 ended successfully, but the serial construction of the tractor was abandoned due to the limited internal volume of the hull, where there was not enough space for artillery crew and ammunition for the gun.
M30- transporter of ammunition and other ammunition for 155-mm M12 self-propelled guns.
M31- in the same 1942, it was found out that a good BREM could be made from the M3 tank. To do this, the guns were replaced with dummies, and a lifting beam with a block, a winch with a pulling force of 60,000 pounds (27.21 tons) and tool boxes were installed at the stern. The prototype under the designation T2, released in September 1942, successfully passed the tests, but was accepted for production only as a "limited supply" vehicle. Its modernized version M31, which appeared in September 1943, became truly massive. Despite the fact that this version was also considered a “limited standard” vehicle, by 1944 the number of converted tanks exceeded a hundred. At the same time, converted tanks of the M3A1 modification were designated as M31V1, and M3A5 as M31V2. In the British army, these vehicles were designated ARV I.
M33- A variant of the BREM M31 converted into a tractor for a heavy 155-mm gun. Improvements were reduced to the dismantling of the beam with the block and the tower, instead of which a compressor and pneumatic hoses were installed to control the brakes of the towed gun. To protect against enemy infantry and attack aircraft, a 12.7-mm Colt-Browning anti-aircraft machine gun was installed on the roof of the hull. After construction and successful trials the first prototype under the designation T1 was issued an order for mass production.
M44- a modernized version of the M33 tractor equipped with a commander's cupola over the hull sponson. A small series has been released.
In addition, the chassis self-propelled howitzers M7 and guns "Sexton" with removed weapons were converted into armored personnel carriers (ARS), called Kangaroo(Kangaroo). In the fighting compartment, all weapons and equipment were dismantled, including anti-aircraft machine guns with a turret, the embrasure was closed with armor plates, additional armor plates were mounted along the sides, and seats for 16 soldiers were installed inside. Armored personnel carriers were reduced to special units and attached to armored units, for example, the 79th Armored Division of Great Britain, which fought in North-Western Europe.
At the beginning of the war, with the participation of M3 tanks, active experiments were carried out to install flamethrowers. A fairly successful model of the E2 flamethrower was tested on the M2A1 medium tank, and in 1941 its improved version of the E3 was installed on the M3. In order to make room for the fire mixture tank, the 75 mm gun was removed. The E3 flamethrower itself was installed instead of the 37 mm gun in the turret. After testing the prototype, it became clear that in such a configuration the tank would become too vulnerable, since a single flamethrower was hardly an adequate weapon for its size.
The second version of the flamethrower tank appeared in 1942. Cannon armament was completely preserved, since the E5R2-M3 portable flamethrower was transported in a stowage inside the fighting compartment and installed instead of a turret machine gun if necessary. However, this option turned out to be unclaimed due to cramped conditions when servicing the flamethrower.
M3 tanks were also used for various experiments as testbeds for experimental designs. In 1941, one tank of the M3E1 modification was assembled, on which the Ford AAA engine was installed, which in the future formed the basis of the power plant for the M4A3 tank. Option M3A5E1 It was distinguished by an experimental Twin Hydromatic transmission, and in 1942 the M3A4 tank was tested with a steering wheel mounted on the rear track roller trolley. In the same period, one of the M3A3(?) tanks was equipped with a suspension with horizontal coil springs.
The Americans also created their own analogue of the British version of the CDL. The lighting equipment was housed in a tower with circular rotation, similar in design to the CDL. The tank was named T10 "Shop Tractor" and, although 355 vehicles were converted, none of them were used in hostilities./p>
It just so happened that it was the British "Grant" that were the first to enter the battles of the Second World War. In January 1942, things were still not going well for the Allies. Having defeated the Italians in the Horn of Africa (Ethiopia, Somalia, Eritrea) in other theaters of operations, the troops of the British Commonwealth retreated everywhere. The most critical situation then developed in Libya, where General E. Rommel launched an offensive against the positions of the 8th British Army under the command of General N. Ritchie and the Free French unit. Unable to withstand the onslaught, the allies left Benghazi and retreated to Gazala, where they managed to stabilize the front for four long months with great difficulty. During this time, the British command managed to assemble a significant grouping of 849 tanks of various types, the basis of the strike power of which was 167 M3 tanks. The "grants" were distributed among three armored formations of the XXX Corps: the 4th armored brigade of the 7th armored division, as well as the 2nd and 22nd armored brigade of the 1st armored division. In addition, the troops of the British Commonwealth had 149 M3 Stewart light tanks, 257 A15 Crusader cruiser tanks, 166 Valentine infantry tanks (various modifications with a 57-mm gun) and 110 Matilda II. In addition, there were several dozen light tanks Mk.VIb and cruising A10 and A13, the combat value of which was not estimated too high.
The Italo-German forces were somewhat more modest but, more importantly, they were inferior in quality to the Allies. In total, under the command of E. Rommel there were 332 German and 228 Italian tanks of the M13 / 40 and M14 / 41 types (this number, apparently, also included L3 / 35 tankettes). The main striking force, contrary to popular belief, the Germans were not “fours”, but “troikas”. By type, they were distributed as follows: Pz.Kpfw.II - 50, Pz.Kpfw.III Ausf.J - 19 (variant with a long-barreled 50-mm gun), Pz.Kpfw.III Ausf.F - 223 (variant with a short-barreled 50 -mm cannon), Pz.Kpfw.IV Ausf.E \ F - 40. Light tanks Pz.Kpfw.I were used in small numbers.
The offensive of the Italo-German troops began on May 26, 1942 on a wide (by local standards) front. As expected, Rommel delivered the main blow with his own forces around Bir Hakeim, and the Italians under the command of General Courvelle attacked on a 20-mile flank. The calculation turned out to be correct - the British did not expect such a maneuver, having previously concentrated their tanks in the center of the front, and after only a day, the threat of complete encirclement loomed over them. While the allies, among whom the Free French units bravely fought, were trying to break out of the almost slammed trap, the 3rd RTR (3rd Royal Tank Regiment of the 4th armored brigade) came to the rescue, almost completely equipped with “grants”.
The first meeting with the “triples” of the 8th German tank regiment (8 Pz.Rgt) on May 27, however, ended for the crews of the “grants”, very unsuccessfully. The British tank group of the 8th Royal Irish Regiment (24 medium and 20 light M3) came under an unexpected flank attack, losing 19 "grants" and almost all of the "stuarts". However, it was too early to rejoice. Having received time to deploy 3 RTR launched a counterattack, causing significant damage to the enemy. According to crew reports, German “twos” and “troikas” were hit by armor-piercing shells from a range of 1100 meters, and for Italian tanks they were hit from an even greater distance - 2750 meters (this is not surprising, given that their frontal armor was only 25-30 mm). The situation for 8 Pz.Rgt was further complicated by the lack of StuG.III self-propelled guns from the 33rd Assault Regiment, which did not have time to arrive at the attack site in time. However, help arrived in the form of 5 Pz.Rgt. tanks, which took part of the blow. The tank battle near Gazala ended in favor of Rommel - having lost 30 of their tanks, the Germans managed to disable 16 "grants", after which the British were forced to retreat.
But the events of May 27 did not end there. On the contrary, the denouement of those terrible was just beginning. In the afternoon, the British literally squeezed the Afrika Korps in the area between Maabus er Rigel, El Adem and Bir Hakeim. One 15th Pz.Div (tank division), already battered in battle, was opposed by three tank brigades (1st, 2nd and 22nd), advancing from three directions. The resulting “cauldron” under normal circumstances did not threaten Rommel with anything other than extermination, but the British troops acted separately, without coordination between the branches of the military, which led to a completely natural result. The Germans not only managed to repel all attacks, but also turned the tide of the second part of the battle. Having recovered from the shock, the Germans applied the old solution, proven over the years - against tanks with anti-shell armor, 88-mm anti-aircraft "flaks" came into action, which were soon joined by Marder self-propelled guns equipped with captured Soviet 76.2-mm F-22 guns. The Italians also made their contribution, whose 75-mm self-propelled guns also “shot” the Allied tanks quite well. The commander of the 135th anti-aircraft artillery regiment, Colonel Volz, later recalled how the battle ended on May 27, 1942:
“We drove for a long time and eventually stumbled upon a convoy of corps headquarters trucks fleeing from the enemy, which themselves were crushed by the transport of the fleeing divisional headquarters. In this chaos, I noticed several 88mm cannons. We rushed through the crowds of soldiers and suddenly came face to face with Rommel. He put a “fuse” in me and said that the anti-aircraft gunners were entirely responsible for the whole mess, because they did not shoot. I forced myself to pull myself together and ran to the guns, stopped them and took three 88-millimeter papers: In no time I stopped another half of the heavy anti-aircraft battery of the operational headquarters of the corps. Suddenly, at a distance of 1500 m, enemy armored vehicles appeared - from 20 to 40 tanks. They pursued a fleeing Afrika Korps transport, which had no artillery cover and was defenseless in the face of enemy tank attacks. At the center of the chaos was Rommel, the headquarters of the Afrika Korps, regimental headquarters, reconnaissance trucks - in a word, the nerve center of the forward combat units.
It seemed that now everything would be decided - a catastrophe was inevitable. In record time we brought our guns into position. As soon as I saw that it was possible to shoot, I ordered to open fire. We had to shoot as quickly and accurately as possible. Fire! The shells rushed to the target. First direct hit. The Briton got up. The tanks that were moving towards us turned back. But here they are ready for a new attack. “Anti-aircraft guns - front! shouted General Nering. “Woltz, you must build anti-aircraft guns in front, use all available guns to provide flank defense.” We felt inspired. Fortunately, Major Gürke appeared with a second heavy battery. Half an hour later, the adjutant of the army headquarters arrived with heavy batteries belonging to the army operational unit, which received orders personally from Rommel. In an atmosphere of extreme haste against British armored vehicles an anti-aircraft gun front was formed with a length of about three kilometers.
German anti-aircraft guns fired from a distance of 1500-1000 meters - quite enough for an armor-piercing projectile to pierce even an 80-mm vertical armor plate, so the “grants” had little chance of surviving. By evening, 24 "grants" were left on the battlefield, lined and burned.
Now the Allies could not stand it any more and the retreat soon turned into a flight with heavy losses in equipment - suffice it to say that on June 13 they had only 70 tanks left. The apogee of German success was a short-term siege and capture of the city of Tobruk on June 15th. This defeat was all the more offensive because the city had huge stocks of weapons, ammunition and food, and was defended by its 33,000-strong garrison, which had the ability to support from the sea, where the British fleet reigned supreme. As trophies, the Germans captured 30 tanks, about 2 thousand cars, 1.5 thousand tons of fuel and hundreds of tons of supplies. Accordingly, the local airfield also fell into their hands. In these battles, almost all the “grants” were lost, but a significant number of them were simply abandoned during the retreat. The overall result was simply stunning - with half the strength, Rommel defeated the 8th British Army, simultaneously advancing 600 km deep into Libyan and Egyptian territory. Allied losses amounted to 80,000 soldiers killed, wounded and captured. The command of the British Commonwealth did not know such a failure since May 1940.
However, Rommel's troops were also not in the best shape. As of July 1st, 1942, only 26 combat-ready tanks remained in the Afrika Korps, compared to about 100 British tanks remaining in Egypt as a reserve. From the current situation, the attack of Cairo and Alexandria looked like pure suicide, but the British, succumbing to panic, had already begun the evacuation of rear units and headquarters. If Rommel had known what was going on behind the lines and the enemy, the war in Africa could have taken a completely different turn.
Unable to move on, the Italo-German troops tried to capture El Alamein, while waiting for reinforcements for the tank units, which only arrived by sea. In many respects, the Allies owed their victory precisely to the fact that in 1942 the British fleet seized the initiative in the Mediterranean Sea, and the aviation of the British Commonwealth countries began to predominate in the air. The supply of tanks was greatly reduced, although transports were still arriving in Libyan ports, transferring improved Pz.Kpfw.IV Ausf.F2 from Italy.
The supply of the allies was much better. After the change of command, British Generals Alexander and Montgomery assembled 935 tanks, among which were the M4 Sherman. For example, in August 1942, the 8th Tank Brigade had 57 "Grants", 31 "Shermans" and 52 "Crusaders", and in the 9th Tank Brigade there were 37 "Grants", 36 "Shermans" and 49 "Crusaders". ". A qualitative improvement became possible after the decision in July 1942 by the US government to send 300 M4 tanks and 100 M7 self-propelled guns as material assistance to the British, who were frankly unsuccessful in Africa.
Against them, Rommel was able to put up 440 tanks of all types (including captured M3s, Matildas and Valentines) and on August 31 a new major offensive began, the purpose of which was to destroy the enemy group at El Alamein. This time the Allies managed to hold out, losing 65 tanks and 1,750 men. The losses of the Germans in armored vehicles were smaller - 50 tanks, but the Afrika Korps lost 3,000 people killed and wounded, without breaking through the defense.
Both sides again went on the defensive, but time clearly played into the hands of the allies. During August-September 1942, significant reinforcements arrived in Egypt, including the 1st American armored division. As a result, the total number of tanks increased to 1441 units, a significant part of which was concentrated near the Libyan border failed. In addition to British vehicles, more than a third of the tanks were now M3 and M4 (253 and 288 units, respectively). The Germans, despite significant losses, were able to collect 540 tanks, of which almost 60% were Italian. Despite the numerical superiority, the allies for a long time did not succeed in inclining the course of the battle in Libya to their side.
Having launched an offensive near El Alamein on October 23, the allied forces advanced very sluggishly, although they managed to push the enemy back from the city. The newly formed 10th Tank Corps, mostly equipped with "grants" and "Shermans", was withdrawn from the battles on October 27, having lost most of its equipment. Particularly fierce battles broke out on November 3-4, when the Germans still had to start a retreat - by this time, the German tank divisions had retained 35-40 combat-ready vehicles, mostly "triples" and "fours", and the total losses left 320 tanks of all types and 55.000 people.
Despite the success achieved, the Allied forces advanced very slowly. The pace of their offensive was only 1.5 km per day, so they reached the Libyan-Tunisian border only in February 1943. This looks somewhat strange considering that on November 8, 1942, Anglo-American troops landed in Morocco and over the next two months occupied not only that country, but also Algeria. Thus, the Afrika Korps was squeezed into the “Tunisian pincers”. The only consolation for Rommel was the arrival of the 5th Panzer Army under the command of General J. Arnim, consisting of only one infantry and one tank division. The advantage of this army was to equip it with new equipment, including six Pz.Kpfw.VI "Tiger" heavy tanks (the only "Tiger-Kompanie" squad in the sPzAbt 501).
In the meantime, the number of tanks "Grant" was increasingly reduced both in combat conditions and for technical reasons, and on December 23 the total number of irretrievably lost tanks reached 350. In this regard, at the beginning of January 1942, 131 remained in the British army. grant”, and in February there were already 88.
Fighting in Tunisia, which began in late December 1942, was initially limited. The Allies were very cautious, but did not hesitate to throw French troops into battle with outdated equipment (suffice it to mention the Renault D1 medium tanks, which had long been taken out of service in the metropolis), which had recently defended Algeria from them. Over the next month, neither side took active action, which created the illusion of the Anglo-American command's inability to attack the enemy. This delusion cost the Allies dearly - already on February 14, the Germans launched a powerful counteroffensive with the forces of three tank divisions (10, 15 and 21 Pz.Div) in the area of the Kasserine passage. German tankers covered a distance of 150 km in five days, destroying and capturing about 200 M3 and M4 tanks. It would seem that military luck was again on the side of Rommel, but it was just the “swan song” of the African Corps, which completely depleted its reserves. After several counterattacks and the pulling of significant forces to the places of breakthroughs, the Allies managed to stop the offensive by February 23, and on March 3 the Germans had to retreat to their previous positions. Now the stay of the remnants of the Italo-German troops in Tunisia was only a matter of the coming months, although there was still no talk of a complete defeat. Having a fourfold superiority in tanks (for other branches of the military, the indicators were slightly more modest), the Allies were able to force the enemy to capitulate only on May 13, 1943. At the same time, by the end of the battles, the Germans still had 120 tanks against 1100 Anglo-American!
The British Grant fought quite a bit during the landing in Sicily. The main tanks of this campaign were, respectively, the medium M4 "Sherman" and the heavy infantry "Churchill". Also, several old Bishop self-propelled guns arrived from North Africa. Somewhat later, already during the landing on the continental part of Italy, M10 and Priest self-propelled guns were used in large numbers, some of which were transferred from Sicily.
Since the "grants" were no longer regarded as full-fledged combat vehicles, they were assigned other tasks. More precisely, it was Sicily that became the first theater of operations, where various auxiliary vehicles based on the M3 tank were used most massively. For example, before the landing, a significant number of Grant Scorpion and BREM minesweepers were prepared.
Also, as armored units were saturated with M4 tanks, older M3s began to be used as command vehicles. Moreover, the improvements were carried out by field workshops, and therefore the tanks were obtained in various configurations. Some of them retained the tower, but without the 37-mm gun, the tower was completely dismantled from others.
The most notable of the "grants" was, quite naturally, the commander's tank, which drove General Montgomery. They say that he has not changed this M3 since the days of El Alamein and literally kept it as a talisman. The tank wore a camouflage pattern of medium sand and olive green patches, somewhat standing out from the rest. The British general did not change this “grant”, at least until the beginning of October 1944, which once again served as an example of the durability of the tank design (however, it practically did not participate in real battles).
True to its obligations, the United States, back in 1941, was considering the possibility of a joint landing with the forces of the British Commonwealth in North Africa, where it was supposed to open a “Second Front” and finally solve the problem with the Italo-German presence on this continent and withdraw France from the war. The final version was approved a few months later - the goal was the Algerian port of Oran, where on November 8, 1942, a large landing of allied forces was landed as part of the Central Operational Group. The American armored forces on this sector of the front were represented by several formations, among which the 1st Armored Division was the largest. The plans of the allies really came true, but not immediately.
Only one unit was equipped with M3 medium tanks - it was the 13th tank floor, formed on July 15, 1940 on the basis of the 13th cavalry regiment of the 7th cavalry brigade.
Of course, the Americans did not immediately enter the battles. After a series of local battles with the French troops, who surrendered a day later, there was a long pause while the Allies regrouped. American tanks from the 2nd battalion received their baptism of fire on November 26, when a battalion of M3 light tanks entered the battle with German tanks from the 190 Pz.Abt.
Further, on November 28, the Americans were given the task of "supporting with fire and maneuver" the Northamptonshire regiment of English infantry, which attacked enemy positions at Jedea. The Americans, who had no combat experience, did not show their best side - some of the tanks were shot by several disguised German anti-tank guns, and the rest had to retreat to their original positions. The following clashes with the Germans for the 13th regiment also did not end in anything good. Suffice it to say that by December 1942, the total losses amounted to 84 light tanks of both battalions and 40 medium tanks of the 2nd battalion. In the same period, the gradual re-equipment of this battalion with M4 tanks began, but they managed to equip only one company with them. Even the American tankers themselves admitted that the medium M3s were clearly weaker than the German Pz.IVs with any gun.
The real defeat was inflicted on the 1st armored division during the battle of Kasserine, where it was opposed by units of the 10th and 21st German tank divisions. Only during February 14-15, 1943, during the battles at Sbeitla, the Germans managed to destroy almost all medium tanks M4 of both battalions of the 1st Tank Regiment and M3 from the 3rd Battalion of the 13th Tank Regiment. Relatively lucky was the 3rd battalion, which until then had remained in the rearguard. The ambushed M3 tanks during the battle on February 17 knocked out five German Pz.III and Pz.IV. Four days later, the battalion, with the support of British units, was thrown to repel enemy attacks near Jabal el-Hamra.
Despite the brutal (by American standards) losses, the use of M3 tanks continued until May 1942, until the remnants of Italian and German troops surrendered in Tunisia. As of the beginning of the month, the 1st division still had 51 medium tanks M3 and 178 M4. "Lee" were part of only three tank battalions and, a small number, in the 2nd battalion of the 13th regiment. The last major operation with their participation took place in March 1943, during the assault on Bizerte - here the M3 tanks supported the offensive of the 34th division. The remaining cars were subsequently transferred to parts of the Free French.
The M3 tanks served quite a bit in the Pacific. The first and last to “sniff the gunpowder” were the tankmen of the 193rd tank battalion of the 27th infantry division, who participated on November 20-23, 1943 in the battles for the Tarawa atoll and the nearby islands of the Gilbert archipelago. Actually, the units of the battalion did not attack Tarawa itself, but the Makin Atoll, located next to it. The operation was planned very carefully, since the landing force had to overcome a wide sandbank, where tanks and soldiers were at a glance in front of Japanese machine-gun nests and artillery.
The medium tanks of Company A (Company A) were part of the second wave of landing and were supposed to support the infantry attacking the Japanese fortifications with the fire of their 75-mm guns, as well as cover the LVT amphibious vehicles with fire. The Japanese were ready to attack and long before the arrival of the Americans managed to build a whole network of defensive structures. The most powerful of them was the Western Tank Barrier (West Tank Barrier), almost impassable for light "Stuarts". However, the 193rd battalion had both types of vehicles.
On the morning of November 23, 1943, medium tanks of the M3A5 modification went into battle, quickly breaking the resistance of the Japanese troops, although the operation did not go exactly as the Americans had planned. Between 09:10 and 09:23, two medium tanks from the Belle Grove transport were first to unload on the shore - they were to provide fire cover for the light tanks, amphibians and infantry that had already unloaded from the first transport vessel. Soon a third transport with 16 amphibians arrived. The first wave of attackers lay down without even passing 100 meters - the situation for the tankers was complicated by the type of terrain - in fact, the tanks moved along a flat beach flooded with water. At the same time, the LVTs were able to advance a little further and the medium tanks of A Company were between them. Despite the fact that the attacking group was moving in shallow water, two M3s hit shell craters that were indistinguishable in muddy water, and stalled. The crews tried to get out of the stopped cars, but were immediately mowed down by machine gun fire. The rest of the tanks tried to maneuver among the reefs, being under constant fire from the 37-mm anti-tank guns of the Japanese. The battalion commander, Captain Robert S. Brown, later admitted that at that moment the battle entered a critical stage. The situation was also complicated by the fact that the tankers were firing at the Japanese fortifications, literally through the discordant ranks of the LVTs, and some of the amphibians were damaged by tank guns. However, the defense was still able to break through in several places. The crew of one of the M3s managed to bypass the line of fire from anti-tank guns and, avoiding an explosion in a minefield, suppressed one machine-gun nest. According to the tank commander, a total of 100 shells were fired, of which at least 30 hit the target, killing many enemy soldiers.
As soon as the situation stabilized, the LVT and M3 crews began a total cleanup of the beach. In fact, between 10:58 and 11:30 the Americans had already taken control of the situation and further, as they say, was a matter of technique. An hour later, the ring around the Barrier was closed, in which the timely approach of the Stuart light tanks played a significant role.
After 12:00, the Japanese began to retreat into the forest, leaving only small groups of soldiers and snipers on the front lines. At this time, the tanks of companies A and F made an advance deep into the island, without engaging in combat with the enemy. At about 12:30 the tank group came under fire from 37 mm anti-tank guns and the F Company commander requested support. Five medium M3s moved forward, beginning to methodically clear the area of machine-gun emplacements. An hour later, the tanks reached the southern end of the island, where they met strong resistance from the Japanese infantry. At this time, G Company, supported by three medium M3s, advanced along the road - here the Japanese equipped two long-term firing points with heavy machine guns and was also intended for a 37-mm gun, but was equipped only with machine guns. The first two bunkers were destroyed fairly quickly, but there were problems with the third one. Nevertheless, by 16:00 the “box” slammed shut. Two American groups squeezed the Japanese troops without any possibility of a breakthrough, and the final chord was the attack of four M3 medium tanks, which suppressed the last large centers of resistance with the fire of their 37-mm and 75-mm guns. The other four M3s were no less successful on the eastern side of the island, and they were actively supported by 105-mm field guns, unloaded after the paratroopers.
In total, by 17:00, the Japanese resistance on Makin began to be of a focal nature, and by the end of the day, the remnants of the defenders began to surrender. The actions of the tankers of the 193rd tank battalion could be assessed as successful, however, the island lacked powerful anti-tank weapons, and there were no Japanese tanks at all. After that, the American army did not use M3 medium tanks in battles (except for vehicles based on them), since in 1943 the basis of the US tank forces were the newer M4 “Sherman”.
While fighting was going on with the German-Italian armies in North Africa, thousands of kilometers away, the “grants” for the first time in their history had to engage in battle with the Japanese. Somewhat strange is the fact that it was not the Americans who fought on them, and not even the British, but the Indians. As we know, until 1947, India was part of the British Commonwealth and its army was obliged to take part in all hostilities conducted by the mother country. For a long time, the Indians, who were under the strict control of the British, received only "recyclables" and then in extremely limited quantities.
Everything changed in February 1942, when the Japanese "suddenly" landed troops in the British colonies of Southeast Asia. The first on the way of the 15th Japanese army was Burma (now Myanmar), under the blows of which three Chinese divisions (5th, 6th and 66th), retreating deep into China, and the British army under the command of General Alexander did not survive. It cannot be said that the capture of Burma was lightning fast, but on May 1 Mandalay was taken, after which almost the entire country was under the control of the Japanese.
General A. Wavel, who commanded the defense of India, formed one British and six Indian divisions, which he brought into two army corps. Also, as a matter of urgency, the organized Indian Tank Corps, by coincidence, received modern equipment in the form of M3 “Stewart” light tanks and medium M3 tanks of various models.
The 251st and 252nd tank brigades received both “native” and export versions of the M3 tanks, but the first of them managed to rearm on the M4A4 “Sherman” even before entering Burma. At the same time, the 252nd brigade, two regiments of which were equipped with "grants", was already sent to the Middle East in June 1942 and placed at the disposal of the 31st Armored Division (31st Armored Division), to reinforce the British contingent. The tanks were unloaded in one of the ports of Iran and sent to Basra (Iraq), closer to the African front. They never had a chance to take part in the battles, and in May 1943 the brigade was re-equipped with M4 tanks and sent to Egypt, where the fighting had long ended.
In total, as of June 30, 1942, about 390 medium tanks were delivered to the Far Eastern borders of the British Empire: 212 were stationed in India, 114 in Burma, and another 57 were sent to Iraq. In April 1943, the situation changed somewhat - 896 tanks were listed only for India.
One of the most distinguished was the 254th Indian tank brigade(254th Indian Tank Brigade), formed on April 1, 1941 in the city of Risalpur and then called the 254th armored brigade. The renaming, carried out on April 1, 1942, was timed to coincide with the supply of new tanks, which were distributed between the 3rd Carabiniers, 149th Royal Armored Corps and 150th Royal Armored Corps Regiment. Another unit (7th Indian Light Cavalry) was equipped with Stewart tanks. Being part of the 14th Army, the brigade was alternately subordinate to the 5th and 7th Indian Infantry Divisions, from the spring of 1943, constantly being in battle.
With "grants", not to mention the "Shermans", the Japanese army had practically nothing to oppose. The main tank on the Burmese sector of the front was the light Ha-Go, whose short-barreled 37-mm cannon could only penetrate the side armor of the M3 from an extremely short distance (no more than 300 meters). The Indians and the British hit the Japanese tanks at a much greater range. Here is how the actions of the Japanese against the Indian "grants" are described:
“In impotent rage, Japanese officers rushed at the tanks with sabers, trying to hit the crew through the viewing slots. In the infantry, suicide squads were organized, who, with mines or Molotov cocktails in their hands, rushed under the tanks or, hiding in the thickets, tried to put mines on bamboo poles under the tracks of the tank.”
Indeed, in the jungles of Burma, the Japanese actively used magnetic mines. In 1943, the British managed to capture several of them and conduct extensive tests. As it turned out, they were ineffective against the side armor of the M3 tanks, but the thinner bottom and roof of the hull were destroyed without much difficulty. To counteract in the first case, the option was chosen with the laying of sandbags, which extinguished the inertia from the mine explosion. Against mines laid on the ground, only mine clearing helped, since the coating of the zimmerite type was not used on British tanks in Burma.
The most difficult trials continued to fall on the lot of the 254th brigade, commanded by Brigadier General R. Skunks. He was the brother of Lieutenant General G.P. Skunks, who strongly opposed the mass use of tanks in the jungle. In his opinion, in areas difficult for tanks to reach, preference should have been given to infantry and artillery, and tanks were given a supporting role. The “brigadier”, in turn, proved the fallacy of this opinion and, in the end, turned out to be right.
In January 1944, during the second battle near Arakan on the Burmese coast, the actions of infantry units were supported by tankers. Among them was the 25th Dragoon Regiment (25th Dragons), equipped with M3 tanks. A few weeks later, in February 1944, the Japanese received reinforcements in Ha-Go tanks and launched a counteroffensive, reaching the positions of the headquarters of the 7th division. Having an advantage in technical support, the British Commonwealth forces then managed to defend a "patch" measuring 800x1500 meters. A role in this success was played by the actions of the M3 tank crews, who provided fire support to the defending units. Air support had no less influence - throughout the entire period of fighting in the encirclement, transport aircraft constantly dropped provisions and ammunition to the besieged troops, while the Japanese units were actually cut off from their supply bases.
After the failure of the counter-offensive, the Japanese General Staff developed a larger operation called "U-Go", the purpose of which was to defeat the intruding British-Indian units. To strengthen the group, Indian units subordinate to Azad Hindu, the self-proclaimed government of India under the control of the Japanese, were also involved. The operation began at the end of March 1944, and one of the most significant objects was the capture of the road from the Impala to Kohima. This time, Skunk had the opportunity to test the theory of using a large mass of tanks in the jungle. The 3rd Regiment of Carabinieri on M3A1 tanks and the 7th Indian Light Cavalry Division on Stuarts went into battle. As a result, there were several tank battles, and the first of these took place on March 20, when a column of "li" tanks of "A" company was attacked by six Japanese "Ha-Go" tanks. The result of this small battle was the destruction of five (according to the Americans, all burned down) and the capture of one Japanese tank. The British lost only one "li", which was destroyed after breaking through the fuel tank and detonating gasoline vapors. In this case, the side 35-mm armor from an armor-piercing projectile of 37 mm caliber at an extremely close distance turned out to be weak protection. However, this was the exception rather than the rule. Further, the crews of the Li tanks provided effective assistance to the British infantry, while the Japanese had practically no anti-tank weapons, with the exception of a few 47-mm anti-tank guns.
This success made it possible to attract larger forces to defeat the enemy, and soon the 149th and 150th RAC regiments, also equipped with Li tanks, were brought up to Kohina. In addition to supporting infantry, M3 tanks were actively used to destroy long-term fortifications and bunkers, which was important in difficult terrain. In fact, in a number of cases, "li" were used as assault guns, since the high-explosive shells of their 75-mm guns were the best suited for destroying all sorts of obstacles.
Ultimately, the operation "U-Go" did not bring the expected results. The Japanese side lost over 60,000 killed and wounded, while the losses of the British Commonwealth forces amounted to just over 16,000 people. By the first days of July, it became clear that the plan to defeat the enemy troops had completely failed, and from that moment Japanese forces fought constant battles to hold the remaining bridgeheads, until the surrender in 1945. In particular, in the winter of 1945, the crews of the 3rd Carabiniers fought at Shwebo and Saganga, and in March they participated in the liberation of Mandalay. After the campaign in Burma ended, the M3 series tanks were decommissioned, and some of the formations that fought on them (such as 3rd Carabiniers) were sent to the metropolis for re-equipment and transfer to more "hot spots" of the British Empire.
So, as mentioned earlier, several dozen M3 tanks of various modifications were handed over to the Free French tankers in the spring of 1943. Continuing to remain in Tunisia and not representing great combat value, the French decided to use the former American “li” to train crews, which they successfully did during next year. French tanks did not take part in the hostilities and messages like "... during the landing in Normandy and in the south of France, the British and American troops were armed with the latest tanks, and the MZ tanks were in the French and Polish divisions that were part of the American army" must be evaluated critically . Of course, there were tanks with such a designation in the French army, but this is not about medium “li”, but about light “stewarts” of the M3 and M5 type.
However, there is another interesting fact. It is generally accepted that the French M3s were not used beyond Africa, however, on the Der Zweite Weltkrieg forum there is a photo of a wrecked tank of this particular brand. The commentary states that this "li" was blown up by a Vietnamese mine during the battles of 1952. So, this issue is still not clear.
Oddly enough, but the fourth place in terms of the number of M3 was Australia. Being one of the most distant British dominions, this island nation constantly needed new technology, which came very late. While things were going on in Europe and Africa, the British were having a tight time in Australia, but at the end of 1942 the situation changed radically. After the delivery of the M4 tanks, the older M3s were sent in mass quantities to the “periphery” and by December the Australians had 502 “grants” and 255 “li”.
One could say that the metropolis clearly deprived its dominion, but this was not entirely true. American tanks were indeed not considered the best, but the Japanese, who occupied the Pacific islands, often had no tanks at all. The strongest opponent for the M3 was perhaps the Shinhoto Chi-Ha medium tank, which had 25 mm frontal armor and an upgraded 47 mm gun. As you can see, in terms of its parameters, the “Japanese” in many respects corresponded to the Italian tanks of the M13 \ 40 type, and we know perfectly well how the meetings with the “grants” ended for them. However, for the most part, Japanese tank formations were equipped with older Chi-Ha and Ha-Go light tanks.
The Australians were not easy guys. Although the front every year moved away from the borders of Australia for thousands of kilometers, this did not stop them from implementing new ideas and experiments. One of such interesting projects was equipping the M3 tank with equipment for overcoming deep fords and swamps. The work was carried out by specialists and technicians of the 4th tank brigade. The solution, from a technical point of view, was absolutely simple. A special casing was attached to the stern of the tank by welding in order to provide air access to the engine. A 12-inch (30.5 cm) high pipe was installed on the roof of the commander's cupola. In trials in 1943, a tank equipped with this equipment was able to ford a depth of 9 feet (2.75 meters), which was only slightly inferior to its full height.
Similar work was carried out in the 5th tank regiment. The idea was similar, but the implementation was somewhat different. To supply air to the engine, a pipe was used, one end of which went out through the commander's cupola, and the other was attached to a hole in the engine compartment. Exhaust gases were removed using a long pipe. Thanks to the almost complete sealing of the hull, it was possible to literally achieve an underwater course - now the tank could overcome water obstacles up to 4.5 meters deep.
Another option involved the installation of two wooden pipes (for air inlet and exhaust outlet) and was the simplest. Of course, such an effect as in previous cases was not achieved, but such a “modernization” was available to any field maintenance team. On trials, the tank easily crossed a ford up to 1.5 meters deep.
In spite of progress made Australian armored forces never acquired underwater tanks. In the presence of well-equipped engineering troops, there was practically no need to re-equip the M3, and besides, since 1943, this tank began to be actively replaced by the M4 Sherman. The cars that were “retired” began to be converted into various auxiliary equipment. So, several M3s were disarmed and converted into M1 and BREM bulldozers. After September 1945, the Australian "li" and "grants" equipped with gasoline engines hastened to write off, but the tanks with diesel engines remained in service. So, by August 1947, 149 more “grants” remained in service, but most of them needed repairs.
During the reform of the Royal Australian Tank Corps, which took place in 1948, it left only one tank floor equipped with "Churchill" and two tank brigades - on "grants" and "matilds", respectively. It is quite understandable that it was difficult to call the presence of tanks of the last two types other than scrap, but in the conditions of a total reduction in the military budget, there was simply nothing to replace them with. In the end, the "grants" were finally withdrawn from service only in 1955. Several tanks were saved and are now on display in museums of armored vehicles.
Separately, it is worth highlighting the order for the Canadian Army. At the end of 1940, an order was received from the Canadian government for 1,157 M3 tanks in a slightly modified version. Changes included the installation of mudguards between the wheeled carts, which were designed to evacuate mud and snow, and additional jettisonable fuel tanks at the stern. In order not to load American enterprises, the order was placed at the factories of the Montreal Locomotive Works, owned by the American Locomotive Company.
M3 tanks made in Canada, unlike the American ones, had a single khaki camouflage. Canadian red-white-red flags were applied to the front on the middle sheet of the transmission and along the sides of the hull. On the sides, and on the front sheet above the flag, a five-digit registration number starting with the letter T was applied with white paint.
Among the other countries that received the M3 tanks was, oddly enough, distant Brazil. Being aloof from the great tank battles, the Brazilians did not disdain not even the newest equipment, especially since it was almost for nothing. Since 1943, under Lend-Lease, 104 tanks of various modifications (M3A3 and M3A5), including several M31s, have been delivered from the USA. At the beginning of 1944, there were plans to send them to Italy, to help the allied forces, who were clearly "stalled" in the mountainous Apennines, but this idea was soon abandoned. After the war, the Brazilian M3 remained in service until the early 1950s, and some vehicles underwent modernization in the same period - instead of diesel engines, they installed Continental radials. The work was carried out by the Central Park of Mechanization on its own. Now one of the surviving M3A5 is installed as a monument in Sao Paulo.
After receiving newer technology, the Brazilians did not send the obsolete M3 for scrap, but sold them to Paraguay. In particular, it is indicated that the Paraguayans received several modernized M3A5s with radial engines. However, there is no detailed information on this. According to official data, only the M4 Sherman and M3 Stewart tanks were in service with the Paraguayan army in the 1940s and 1950s.
The failures of the first months of the war against Germany and its allies by September 1941 put the Red Army in a very difficult situation. Having lost during this time, according to the most conservative estimates, about 25,000 tanks Soviet troops constantly rolled back, leaving the enemy huge industrial areas. The occupation of Ukraine and the blockade of Leningrad looked especially hard against the general background. Military enterprises had to be urgently evacuated, including the Kharkov Locomotive Plant, which was the main one for the production of T-34 tanks. Deliveries to the front heavy tanks KV also decreased - the Leningrad Kirov Plant turned out to be blocked. It was possible to restore the number of tanks of this type only by the beginning of 1942, after the deployment of evacuated factories in the Urals.
But the front did not wait. Tanks were required immediately, and it was difficult to fight on the T-40 and T-60 alone, produced at the Moscow plant No. 1. The way out was seen in the supply of equipment from abroad. Soviet military commissions went to Great Britain already in August 1941, where they quickly managed to agree on the supply of the following tanks: the infantry A12 “Matilda’ II”, the infantry “Valentine” Mk.I and the landing A17 “Tetrarch”. Following them, a contract was signed for the purchase of heavy infantry tanks A22 "Churchill" and transporters "Universal Carrier".
Much more modest was the story of the Americans, whose “range” turned out to be not so wide. As in the case of the British Lend-Lease, the Soviet representatives were offered M3A1 light tanks and M3 medium tanks. The latter were produced in significant quantities and were quite affordable for export deliveries. Although by this time more modern variants like the M3A1 and M3A3 were available, the choice was made in favor of the earlier M3. Perhaps the mass character of this modification played a role. In any case, 1386 tanks were shipped to the Soviet side, but military acceptance GBTU accepted only 976. Considering that the Americans considered 417 M3 and M4 tanks to be “drowned”, the Soviet Union received less than was stipulated in the contract.
The tanks were delivered in convoys via Murmansk, but some of them arrived via Iran. Such an unusual route was due to the presence of “extra” M3s in the American tank units that fought in North Africa. Since the spring of 1942, active rearmament with the M4 Sherman began, and older tanks were gradually withdrawn from combat. As a result, part of the M3 was sent to the USSR, despite the fact that delivery by land routes through the Middle East was somewhat faster.
The Soviet tankmen did not like the American tank. This is not an unfounded statement - for the entire period of operation, the M3 practically did not deserve good reviews. Of course, in 1942, the "American" was clearly more comfortable for a crew of six, had a smoother ride and was not difficult to manage. According to these parameters, the M3 looked clearly better than the same “thirty-fours”, the workmanship of which left much to be desired. But let's not forget that the production of tanks in the United States was carried out in "greenhouse" conditions, while the Soviet industry literally worked to the point of wear and tear under the most unfavorable circumstances. However, six months later, the quality level of the T-34 was raised to the required levels, and the M3 turned out to be an “outsider” among the exported tanks.
In the Soviet nomenclature, designations such as A12 or their own names did not take root. Instead, various abbreviations were used, which still causes confusion when analyzing the types of tanks used in a particular operation. Let's deal with this issue in more detail:
A12 Matilda – Mk II or MK II
A22 "Churchill" – Mk IV or MK IV(sometimes even MK.IU, where "U" is a substitute for the Latin numeral "V")
M3 and M3A1- light tank M3l or M3L
M3- medium tank M3s or M3S
"Universal" – "Universal"
In the case of American tanks, the letters “C” and “L” sometimes completely disappeared from the reports, so in some cases it is now very problematic to determine which of the M3s was used in battles. In addition, in our writers, these tanks are commonly referred to as "grants", which is not entirely true, since most of them still belonged to the "native" modification of the M3 for the US Army and it would be more appropriate to use the name "Lee". However, in order not to introduce confusion, we will also adhere to this tradition.
The M3 and M3A1 tanks sent to the Soviet Union were also not repainted and retained American registration numbers. Moreover, American stars were simply repainted red. The only striking difference was the names on the sides and front sheets, which were not proper names, but rather slogans: “For our Soviet Motherland”, “Death to fascism”, “We will avenge the tortured Soviet people”, “Soviet heroes”, “Under the banner of Lenin forward to victory”, etc. However, the first M3s that arrived in the USSR received only tactical numbers. white color, which could be applied both to the frontal hull sheet and the turret, and to the sides in the engine area. So far, it has not been possible to trace any general scheme for applying these numbers. Tanks operated in winter were repainted with washable white paint.
In addition, by agreement with the allies, since 1945 on soviet tanks on top of the tower around the perimeter, a white stripe of recognition began to be applied. In turn, the Americans and the British drew two stripes. This was done for a reason - the fronts were approaching and not all fighters on both sides knew what a Soviet or American tank looked like - in such a situation, the stripes helped to more accurately determine the identity of the vehicle.
Among the first units to receive M3 medium tanks was the 114th Tank Brigade. Its formation began in February 1942 in the city of Slobodsky (Kirov region), but the material part was received in the city of Gorky over the next two months. It is very interesting that almost all the equipment used in the 114th brigade was American: Dodge, Ford-6 and Chevrolet trucks, Harley-Davidson motorcycles, etc. The basis of the brigade was the 319th and 320th tank battalions - in total, the 114th brigade had 69 M3s and M3l tanks.
It was not until mid-May 1942 that the formation of the brigade was completed in full, when the Soviet offensive began on the Barvenkovsky ledge. The American tanks took the first battle on May 16 - on this day, the brigade entered the battle in the area of \u200b\u200bSavintsev, Muzorov Bayrak and Malaya Komissarovka. After the failure of the operation, the 114th brigade was urgently transferred to the area of Valakleya, V.-Burluk, Barvenkovo to release the encircled formations of the 6th and 12th armies. Based on the current situation, on May 23, the brigade was transferred to the control of the Consolidated Tank Corps, which also included the 64th brigade and the 92nd separate tank battalion, which brought its total strength to 102 tanks. The first success was achieved on May 25, when, in cooperation with infantry formations, the corps participated in the liberation of the city of Csepel. There were no losses in American tanks 25, but during the day the Soviet troops lost 29 tanks, knocking out and destroying 19 German ones. On the morning of May 26, a new order was received - to break through the defensive orders of the German units from the outside, squeezing the Soviet grouping into "pincers". The reports noted that during May 26-27, tankers fought stubborn battles with the enemy and, having overcome his resistance, were able to break through the encirclement, providing assistance to units of the 300th Infantry Division.
The total losses in the tanks also turned out to be rather big. Despite the fact that not a single tank was lost on the 26th, as of the evening of May 27th, the 114th brigade had only five M3s and five T-60s. According to unspecified data, along with the M3s, older medium tanks M2A1 were also used, so the total number given includes these vehicles. The last major battle with the participation of M3s took place on that very day in the area between the settlements of Krasnaya Gusarovka and Gusarovka, where the remaining American tanks by that time were knocked out.
The 5th Guards Tank Brigade took part in the unsuccessful offensive near Barvenkovo, but unlike the 114th brigade, its battle path turned out to be more thorny. Before the start of the operation, the guards had only Soviet-made tanks, mainly T-34s and T-60s. After a successful breakthrough of the German defense, the 5th Guards Brigade. was surrounded, having lost most of her equipment. The breakthrough, undertaken on the morning of May 26, was led by the tanks of the 5th Guards Tank Brigade, led by its commander, Major General Mikhailov - at that time, 7 T-34s, 6 T-60s and one KV-1 remained in the brigade. The largest tank group from the 21st Tank Corps (60 vehicles of various types) was concentrated in the Lozovenka area. In total, 74 tanks and 22 thousand people went on the attack, of which only 5000 and five tanks of the 5th Guards Brigade came out to their own.
After that, the 5th Guards Brigade. was reorganized and equipped with foreign technology. A few months later, the brigade was transferred to the North Caucasian Front, where the Soviet offensive was more successful. Further, tracking the quantitative composition is somewhat problematic, since modern sources provide conflicting data.
For example, you can find a mention that after the reorganization, the place of the "thirty-fours" was taken by English and American tanks: 18 "Valentine", 16 M3l, 4 M3s and 2 M4A2. However, the monograph “Breakthrough of the Blue Line” (“Military Chronicle” No. 3-2004) provides other information as of September 13, the brigade had 21 T-34 and M4A2 medium tanks, as well as 14 “Valentine” (not counting eight self-propelled guns SU-76) . As of September 26, the total number of tanks is estimated at 44 units, but there was not a single "American" among them (40 "Valentine", 3 T-34, 1 BT-7). Based on these data, we can conclude that if the "grants" were operated as part of the 5th Guards. tbr., then an extremely short time.
The only tank unit that took part in the liberation of the Caucasus and was equipped with "grants" in a sufficient number of operations was only the 257th tank regiment, subordinate to the command of the 56th army. The first battle in the framework of this large-scale operation, "grants" and "stuarts" took place in the early morning of September 14, 1943. The tankers, in cooperation with the rifle units, had to break through the front line of the enemy’s defense in the area of \u200b\u200bNovyy and heights 95.0. The Germans resisted very fiercely, in which the minefields contributed a lot. However, by the middle of the day, the infantry managed to find a passage between the fields, and three tanks immediately slipped through this narrow "gallery". Having broken into the outskirts of the New settlement, the tankers failed to gain a foothold, since the infantry could not pass behind them - all three tanks were hit by artillery, the rest retreated to regroup. The total losses that day amounted to six M3s tanks.
The offensive resumed on September 15, when the front line of the enemy’s defense was nevertheless managed to break through, it was decided to postpone further advance for the next day due to darkness. The task assigned to the 257th regiment was to force the Psif River and reach the Pebeps River. Having established interaction with the infantry, by 10:00 a.m. the tankers managed to break through the intermediate line of defense and by the end of the day captured the height of 149.8. During September 18-21, the regiment, having crossed the Psif river, fought stubborn battles in the area of \u200b\u200bthe settlement of Ilyichevsky, Osnva, Kars. Although the combat mission was partially completed, however, irretrievable losses amounted to only 5 M3l and M3s tanks. One of the reasons for the slow advance of the tanks of the 257th TP was the complete absence of their own artillery.
After the regrouping, the offensive of tank formations resumed on September 22-23, when the Chekups River was forced. In the afternoon, Soviet tanks came under fire from four camouflaged self-propelled guns, after which they were attacked by German tanks. Having repelled this sudden attack from the enemy, the Soviet tankers temporarily went on the defensive and all day on September 24 they were regrouping. Losses for the previous two days amounted to 5 "grants". In total, when the Soviet troops prepared for the liberation of the Taman Peninsula (October 2, 1943), only 13 vehicles remained in the 357th tank regiment. Other tank formations also did not differ in complete equipment: the 63rd brigade - 17 T-34s, the 85th tank brigade - 13 T-34s, the 1449th sap - 9 SU-122s. Nevertheless, it was they who were given the task of capturing the Vyshestebliyevskaya field and preventing the enemy from reaching the Kiziltash estuary. In the most difficult battles from October 2 to 9, the tankers, being under constant fire from long-range artillery and anti-tank weapons, managed to fully complete the task, after which a long respite was obtained.
After the Caucasus, the 257th separate tank regiment was transferred to the west and included in the Separate Primorsky Army. The new task was even more difficult than the previous one - it was necessary to liberate the Crimea. Being on the Kerch bridgehead, the 257th detachment advanced together with the 85th and 244th tank regiments, as well as the 1499th sap, equipped with SU-152 self-propelled guns. In total there were 80 tanks and 20 self-propelled guns. Here is how the actions of the regiment are described in the book "Difficulties of Liberation" (given with abbreviations):
“On the morning of April 11, by order of the commander, he set out from waiting positions in the Adzhimushkay area and an army mobile detachment, in whose head the first battalion of the 257th tank regiment moved with a landing of submachine gunners and two army reconnaissance companies. The army mobile detachment received the task, moving along the Kerch-Sultanovka highway behind the mobile detachment of the 16th rifle corps, to capture the forces of the corps in the village of Mikhailovka, turn around to the south of the mobile detachment of the 16th corps and, in cooperation with it, go into a rapid pursuit of the enemy along paths parallel to the withdrawal the main forces of the 5th army corps of the enemy in the general direction of the settlements of Marfaka, Dzhav-Tobe, Uzun-Ayak, Arma-Eli with the task of reaching the flank and rear of the retreating Kerch group of Germans and, together with the troops of the army pursuing the enemy from the front, encircle and destroy it.
Having deployed at the indicated line and having as a forward detachment one tank battalion with a landing of machine gunners and two army reconnaissance companies in vehicles, the 257th tank regiment on the move shot down small enemy units defending along the Turkish Wall, and by 14.00 on April 11 bypassed from the north west captured the village of Marfovka, defeating the 9th cavalry regiment of the 6th cavalry division of the Romanians and inflicting heavy losses on the 4th artillery regiment of the same division. Most of the soldiers and officers of the 9th cavalry regiment were taken prisoner, including the commander of this regiment with his headquarters ...
... The army mobile detachment during the night of April 13 completed the liquidation of the small enemy groups remaining in the Feodosia region and, having replenished with fuel, in the first half of the day made a forced march along the Feodosia - Karasubazar highway. Due to the lack of fuel, the army detachment continued to advance in the direction of the village of Zuya with only one tank company of the 257th tank regiment, which had machine gunners on its armor. By the end of April 13, a tank company, in cooperation with the forward detachment of the 32nd Guards Rifle Division, captured the village ...
... On April 23, the main forces of the 11th and 16th rifle corps approached Sevastopol, and the front commander decided to launch a second offensive with larger forces. Up to 5 rifle divisions and tank units of the Primorsky Army (one tank brigade - 63rd Tamanskaya and 3 tank regiments - 85th, 257th and 244th) and the 19th tank corps, which by that time numbered a total of 42 tanks and 28 self-propelled guns. Artillery preparation was set to last one hour. The 8th Air Army was supposed to support the offensive ...
The 257th separate tank regiment, with 30 tanks in service, on the orders of the commander of the 16th rifle corps, interacting with units of the 383rd rifle division, attacked the enemy in the direction of the northern outskirts of the village of Kadykovka, a fork highways and mountain heights. At 11.30, the tanks of the regiment passed the front line of the enemy's defense and reached the Nameless Farm, 1.5 km northwest of Kadykovka. Here the tanks were met with heavy anti-tank fire, and attempts to move forward through the hollow were unsuccessful. By the end of the day, the regiment, having lost 5 tanks burned out and 6 damaged, returned to its original positions.
The offensive on April 23 showed that, despite the excellent work of artillery and aviation, it was not possible to destroy the defensive structures, although in some directions the infantry advanced 2–3 km and occupied the enemy’s front trenches. According to intelligence, the enemy still had 72,700 soldiers and officers on the bridgehead, 1345 artillery pieces, 430 mortars, 2355 machine guns, as well as 50 tanks and self-propelled guns.
On April 24, the tank units of the Primorsky Army and the 19th Tank Corps were once again used to break through to Sapun Gora through the Bolshevik collective farm, having suffered heavy losses, but were not successful. During the two days of the battle, 97 tanks and self-propelled guns were lost (burned out and lined). After a series of unsuccessful attacks, by order of the chief of staff of the front and the commander of the Primorsky Army, the corps was withdrawn to the area of \u200b\u200bthe village of Kamara, where it began repairing tanks and preparing for further hostilities.
Indeed, the losses in technology were very large. As of May 7, 1944, the OTA had only 166 tanks and 30 self-propelled guns, while there were practically no replenishments over the above period of time. The number of the 257th detachment also decreased, but did not look catastrophic - at that time there were 22 tanks left in the regiment. The operation carried out on the same day to destroy the German troops, who occupied a tough defense on Sapun Gora, was successful. As a result, by the end of the day, the 242nd Mountain Rifle Division with the 257th Tank Regiment were 300 meters from the eastern outskirts of the Karan settlement and, with the support of the 16th Corps, captured it on the afternoon of May 8th.
Now the time has come for the liberation of Sevastopol - on the morning of May 9, let the enemy pull up reserves and regroup, Soviet tankers and infantry units broke into the city. The resistance of the German troops was very strong - suffice it to say that the remnants of tank and assault regiments operated in the city, equipped with Pz.III and Pz.IV of various options, as well as 75-mm StuG III anti-tank self-propelled guns. And yet, the tankers of the 257th detachment and the infantry of the 83rd marine rifle managed to drive the enemy out of the Georgievsky monastery area, completely clearing the area by 17:00. After the completion of the operation to liberate the Crimea, the remaining Grant and Stuart tanks were taken to the rear, and the 25th separate tank regiment received new T-34-85 tanks.
The operation to withdraw troops from the encirclement near Kharkov did not have time to end, when in June 1942 a new, no less large-scale operation began on the Bryansk Front. The Voronezh direction was chosen as a priority, in which both sides concentrated significant tank forces. The command of the Red Army, having received in mid-June information about the regrouping of enemy troops and the concentration of troops in the area of \u200b\u200bthe cities of Kolpny, Shchigry and Kursk, decided to form an "adequate counterweight". The Soviet “armored fist” outnumbered the German one, numbering about 1640 tanks against 795: 191 KB, 650 T-34-76, 42 BT and T-26, as well as 757 light and infantry tanks of other types (T-60, T -70, "Valentine", etc.) There were 12 tank brigades alone, but only one of them was equipped with American tanks.
As part of the 192nd brigade by the end of June 1942, there were 30 ((according to other sources - 31) M3l and 14 M3s, divided between the 416th and 417th separate tank battalions, and before the start of the offensive, all tanks were in good order (which is impossible It was said about the T-34 and KV). The brigade was part of the 61st Army and actually spent most of the time on the rear lines. Considering the unique design of the M3s, this tank could be more useful as a weapon to fight enemy armored vehicles from ambushes or shelters. The power of the 75-mm gun was just enough to effectively combat the German tanks Pz.Kpfw.III Ausf.G\H, equipped with 50-mm cannons with a barrel length of 60 calibers and 30-mm frontal armor. the basis of the German tank units in the battle in the Voronezh direction. Actually, it is difficult to say anything definite about the success of the use of "grants" in the summer of 1942 on the Bryansk Front, since reliable information regarding their combat work is still not found. Statistics By August, the number of combat units in the brigade increased to 64 tanks by adding five heavy KV-1 and eight infantry "Churchill". However, on October 1, 1942, the 192nd brigade retained only 38 vehicles: 14 M3l, 25 M3s and 3 Universal armored personnel carriers. Thus, there were no losses among the “grants” at all, or they were replenished at the expense of reserves, which is very doubtful.
The last peak in the activity of using the M3 in the ranks of the Red Army came in the summer of 1943. As you might guess, the largest grouping of American tanks was concentrated to carry out a defensive operation on the Kursk Bulge. As of July 1, the Central Front had at least four tank units equipped with "Americans": So, only in the 48th Army of the Central Front there were 85 "grants": 30 M3s, 8 M3l and 8 SU-76s, in the 193rd detachment - 55 M3s and 3 SU-76s. The Voronezh Front had a slightly smaller number of M3 medium tanks: the 245th detachment - 26 (according to other sources 27) M3l and 12 M3s, the 230th detachment - 6 M3s and 32 M3l.
The most difficult test fell on the lot of the 230th detachment, which was in the reserve of the 52nd Guards Rifle Division. On the afternoon of July 5, the infantrymen repulsed several powerful attacks of the 2nd SS Panzer Corps, but by 15:00 an acute shortage of ammunition began to affect. The situation became critical when German aircraft burned 13 vehicles with shells urgently delivered to the front line. The division was fragmented into several parts, but even then the guards did not retreat, continuing to fight in a partial environment. In order to prevent the enemy from completing the pursuit and completely closing the ring, the command of the 52nd Guards Rifle Division issued an order to withdraw and concentrate in the area of the village of Bykhovka, where three companies of the 230th detachment were in reserve. The fourth company buried its tanks in the ground at a height of 227.4, in anticipation of a German breakthrough. The tankers also received the task of covering the infantry units at about 15:00. Subordinating to the command of the infantry division, the commander of the tank regiment D.A. Shcherbakov sent one company of tanks against the armored group of the Das Riech division, and the other two against the avant-garde of the Leibstandart division. The first battle took place about 6 km north of Berezov at a height of 233.3. Second, more large group"Americans" met the enemy 1.5 km south of Bykhovka. In both cases, both the qualitative and quantitative advantage was on the side of the Germans, whose armored groups were based on Pz.IV tanks. Armor-piercing shells fired from long-barreled guns successfully pierced the frontal armor of "grants" and "stuarts" from a distance of more than a kilometer. In fact, the oncoming battle did not work out - the Germans simply shot the Soviet tanks that attacked them. The battle at Hill 233.3 ended between 15:45 and 16:00 with the loss of seven M3 tanks, although it is not specified which type they belonged to. Judging by the surviving photographs, at least two "grants" were completely destroyed. There is no data on losses from the German side. Nevertheless, the death of almost an entire company of the 230th detachment was not in vain - the tankers completed their task, delaying the advance of the enemy and giving the infantry formations the opportunity to regroup.
No less difficult was the fate of the "grants" of the 245th rep. During the fighting in the area of the villages of Cherkasskoye and Korovino (Yakovlevsky district of the Belgorod region), from July 4 to August 28, 1943, the regiment lost all materiel and was assigned to reform.
Probably the most "variegated" was the composition of the 91st separate tank regiment of the 4th Army of the Karelian Front. At the beginning of 1943, Soviet divers raised 12 M3 tanks from a sunken vehicle, which were then repaired in the workshops of the 297th repair battalion. However, the regiment received only 11 vehicles, since the 12th had to be dismantled for spare parts. Unfortunately, information about the combat use of these machines has not yet been found. From the report on May 27, 1944, it is known that the 91st detachment had 14 BT-7 tanks, five BT-5s and one M3s - it is possible that some of the American vehicles failed for technical reasons.
After the completion of operations near Kursk and Kharkov, the number of M3 medium tanks began to steadily decline. In the southern direction, the remaining "grants" were gradually withdrawn to the rear, and in the central sectors of the front they disappeared due to natural attrition (combat losses, impossibility of repair, lack of spare parts, etc.) Apparently, the last formation that used M3s tanks on Soviet-German front, became the 41st Tank Brigade of the 5th Tank Corps of the 1st Baltic Front. According to the summary for the evening of November 13, 1943, the brigade had 61 "thirty-fours". However, by the beginning of March 1944, the 41st brigade had only 24 T-34-76 and 38 (!) "Grants". Where the American-made tanks were transferred from is not specified. It is possible that the "sources" were formations of other fronts, which at that time were being retrained for new equipment. It is also known that by the time the 5th TC was transferred to the 2nd Baltic Front (in April 1944), 204 T-34s of various modifications and 20 "grants" remained in it. They finally broke up with the M3s only at the end of May 1944, when the 41st brigade mastered the much more modern T-34-85, on which it ended the war.
The Soviet M3s played its last "chord" in the summer of 1945. The only tank of this type was part of the 267th Tank Regiment of the Trans-Baikal Front. Apparently, the “grant” got to the Far East a little later than the others, and due to a combination of circumstances, he managed to successfully survive until August 1945, when Soviet troops entered Manchuria. By this time, the regiment was based on the British "Valentine" in the amount of 40 units, but there was also one "Churchill" and M3l each. It is possible that it was here that the M3s “shaken the old days” for the last time in battles with the Japanese.
Of the other compounds that used "grants", the following can be noted:
92nd Tank Brigade of the 31st Army
101st Tank Brigade of the 31st Army(Western Front), as of August 1942, had 30 M3s and 30 M3l;
15th tank brigade(Transcaucasian Front), as of November 1, 1942, had 1 M3s, 16 M3l and 22 "Valentine";
21st Training Tank Regiment(Transcaucasian Front), as of November 1, 1942, had 1 M3s, 4 M3l, 12 T-26s and 31 T-60s;
196th tank brigade(Kalinin Front), as of November 1942, had 4 M3s, 4 M3l, 4 T-60s, 10 Matilda IIs and 1 Valentine;
241st tank brigade(Don Front), as of February 1943, had 3 M3s and 3 M3l;
separate tank battalion of the 53rd Army of the North-Western Front(formed from repaired equipment), as of February 1943, had 13 tanks: 7 T-34, 4 T-70, 1 KV-1 and 1 M3s;
37th Tank Regiment of the Shock Army, in February 1943, had 10 M3s and 7 M3l (by April, their number was reduced to 4 and 3 vehicles, respectively);
39th Separate Tank Brigade of the 4th Shock Army, as of March 1944, there was 1 M3s;
41st Tank Brigade, 5th Tank Corps, as of March 1944, there were 38 M3s (another 20 M3s belonging to the 5th shopping mall operated on the 2nd Baltic Front);
5th Army(2nd Belorussian Front), as of June 1944, it included 3 M3s tanks.
Outdated "grants" periodically tried to find another use. For example, in the spring of 1943, the possibility of using a certain number of M3 tanks as armored personnel carriers was seriously discussed. The Soviet version of "Kangaroo" differed significantly from the British-American counterpart, if only in that the dismantling of weapons and the turret was not provided. In fact, a variant of an armored personnel carrier tank was proposed, inside the fighting compartment of which it was possible to place an assault force of 10 infantrymen with PPSh assault rifles. The negative point was the impossibility of firing from both guns. Apparently, while the discussion was going on, the strength of the M3s managed to decrease and the issue of the transfer of troops disappeared by itself. However, it is possible that in front-line conditions "grants" could be used in this way.
As for the use of M3 tanks on the side of Germany and its allies, then unequivocal assessment no. The first trophies appeared in the Wehrmacht after the unsuccessful offensive of the British Commonwealth forces in North Africa. As you know, not all the "grants" burned down on the battlefield - some of the tanks were abandoned for technical reasons and, after a small repair, went back into operation, but on the other side. Apparently, at least two dozen fully combat-ready vehicles fell into the hands of the Germans, but not all of them were used in battles. At least in modern sources there is no mention of encounters with captured M3s. There is also no information about “secondary” trophies, when previously captured tanks were again transferred to the previous owners. Most likely, the Germans used the “grants” as anti-tank weapons or as infantry fire support vehicles. AT german army American tanks were designated Pz.KpfW.M3 744(a) "Lee".
It is authentically known that one of the captured tanks (judging by the footage of the newsreel it was M3A3 - the body was welded) was being tested in Germany. Interestingly, in 1943, the obviously outdated American vehicle was compared with the latest Pz.Kpfw.V "Panther" and Pz.Kpfw.VI "Tiger". Of course, the M3 lost to them in all respects.
Also, more than a hundred tanks of the M3 type went to the Germans in 1942-1943. on the Eastern Front. They managed to return some of the vehicles to service - judging by the German photographs, single copies were used in the battles near Mtsensk and in the occupied territories to reinforce the rear units.
There is no exact information about the coloring of captured tanks captured by the Germans. According to German photographs, it can now be established that all captured M3s (regardless of the theater of operations) retained their previous color. Apparently, the Germans did not apply tactical numbers, or they did it with rare exceptions (sometimes they simply painted numbers on the sides of the turret and hull with light paint). hallmark there were large crosses on the sides, turret and frontal hull plate. In some cases, the height of the crosses reached the full height of the sponson.
It is possible that in the fall of 1942, M3 tanks were captured by Italian troops, both in Africa and in the Soviet Union. Regarding the Soviet M3, we can definitely say that the Italians did not receive a single machine in working condition. But in Libya and Egypt, there may have been precedents for the short-term use of British ‘grants’ and ‘li’.
The Romanian army received at the beginning of 1943 from the good-natured Germans a whole "assortment" of Soviet captured equipment. To make up for the losses and strengthen the grouping of the Romanian troops in the Crimea, 4 amphibious tanks T-37A and T-38, 4 M3s, 5 M3l, 4 "Valentine IV" and 19 other tanks were sent, including several T-34 and T-60. It is claimed that all this technique was used only for training purposes.

The only medium tank adopted by the US Army between the two world wars was the M2, which was actually an oversized M2A4 light tank.
M2 - this unremarkable combat vehicle - became a milestone for American tank building, since it was on its basis that the massive M3 medium tank was created, which became the "school desk" of the US Army tank forces.
CREATION
The first version of the tank, which began production in the summer of 1939 at the Rock Island State Arsenal, was armed with a 37-mm M6 cannon mounted in a multi-faceted conical turret and eight Browning M1919A4 machine guns (four in the corner sponsons of the hull, two in the front plate corps and two - anti-aircraft). The crew consisted of six people. On the second version - M2A1 - they used the turret from the M2A4 light tank, slightly increased the armor and boosted the engine. The mass production of the latter - 1000 units - was supposed to be deployed at the new arsenal in Detroit, but on August 28, 1940, the order was canceled.
Events in Europe had a strong influence on this decision: the defeat of Poland and France, the amazing successes of the German tank forces. A great impression was made on the American military and the technical characteristics of German tanks. Against their background, it became quite clear that, in general, a good 37-mm gun as a weapon for a medium tank is completely unpromising. It was impossible to place the available 75-mm gun in a turret borrowed from a light tank. It was then that the idea arose to install it in the right side sponson of the M2A1 tank, of course, having made the necessary finishing touches. The idea was implemented quite quickly - on June 13, 1940, the tactical and technical requirements for the new tank were approved by the department of armaments, and a month later it was standardized under the designation M3. A full-size wooden model for display to representatives of the armored forces (Armored Force) and industry was made at the Rock Island Arsenal only at the end of August 1940. The first prototype handed over for testing at the Aberdeen Proving Grounds (Aberdeen Proving Grounds) in March 1941.
FROM "LI" TO "GRANT"
The defeat of the British troops on the European continent and the loss of almost 2/3 of their tanks forced the British to turn to their overseas ally for help. Great Britain could not quickly make up for the losses due to its own production. At the end of June 1940, a special mission arrived in the United States from the shores of Foggy Albion. The proposal to expand the production of British tanks at American factories did not arouse any enthusiasm among the Americans. This was explained by quite pragmatic considerations. In the context of the impending German invasion of the British Isles, the Americans did not have any confidence in the development of events in favor of England, therefore, they did not want to load their factories with the production of military equipment that did not meet American standards. It could only be about the supply of American combat vehicles. This was facilitated by the adoption of the Lend-Lease Act on March 11, 1941, which extended to Great Britain on the same day.
Nevertheless, the British insisted on making changes to the original design of the tank. In particular, they were not satisfied with the too high height of the M3. According to the English project, a new cast tower was made, lower and wider than the standard one, but having the same ring diameter. Instead of a commander's turret, they limited themselves to a round rotating double hatch. At the same time, the height decreased by only 102 mm.
An English radio station was placed in the aft niche of the tower, boxes for equipment - along the sides of the aft hull. Since the tanks were intended mainly for combat operations in Africa, they were equipped with specially shaped wings that reduced the dust cloud from the tracks. The M3 converted in this way received the official English name General Grant I. At the same time, the British, who were not devoid of humor, called the standard American model General Lee I, thus assigning the names of American generals who fought each other during the US Civil War to variants of the same tank.
MODIFICATIONS
In addition to the main and most numerous modification - M3, there were others. From February to August 1942, the American Locomotive company produced 300 М3А1, which differed from the basic version only in a cast body. It should be mentioned that a certain number of M3 and M3A1 were equipped with a Guiberson T-1400-2 diesel engine. In January 1942, another locomotive building enterprise, Baldwin Locomotive, manufactured 12 M3A2 tanks with a welded hull, and then switched to the production of the M3A3 variant. It differed from the M3A2 in the General Motors 6046 G-71 diesel power plant with a capacity of 375 hp. With. On some machines, the landing hatch in the left side of the hull was welded. Until December 1942, 322 M3A3s were manufactured. From June to August 1942, Detroit Tank Arsenal produced 109 vehicles of the M3A4 version with a Chrysler A57 Multibank engine with a capacity of 370 hp. s, which was a power unit of five automobile motors. The length of the riveted hull had to be increased to 6147 mm. The hatch on the left side of the hull was completely eliminated. The number of caterpillar tracks has increased to 83.
The design of the suspension bogies has been improved. Finally, from January to December 1942, Baldwin Locomotive produced 591 M3A5-M3s with a General Motors 6046 G-71 diesel engine.
All these modifications did not fundamentally differ from the basic version in terms of their tactical and technical characteristics. The reasons that prompted the factories to start producing them were more of a technological nature, taking into account the capabilities of a particular enterprise, traditional allied factories, etc.
M3 TANK DESIGN
The M3 received its baptism of fire in North Africa, in the battle of Gazala on May 27, 1942 as part of the 7th British Panzer Division. 167 "Grants" turned out to be an unpleasant surprise for the Germans and Italians due to their 75-mm guns.
The battle at El Alamein in October 1942 in the British 8th Army, the number of "Grants" reached 600. As part of the British troops, these tanks fought in Africa until the complete defeat of the German-Italian army of Rommel. At the same time, American crews also took part in the hostilities.
A small number of M3s were also delivered to the UK. As early as March 1945, the Lees fought against Japanese troops in Burma as part of the 150th Regiment of the Royal Tank Corps.
M3 IN BATTLE
American M3s first saw action in the Philippines as part of the 192nd Tank Battalion. Basically, they were used for educational purposes both in the United States and abroad. For example, regiments of the 1st Panzer Division of the US Army, deployed in the spring of 1942 to Northern Ireland, were armed with combat vehicles of this type. One of them - the 13th - took part in the landing of American troops in Morocco and in subsequent battles in Tunisia, by the end of which almost all Lees were replaced by Shermans. In November 1943, the M3, as part of the 193rd tank battalion, was used to a limited extent in battles in the Pacific Islands on the Mekin Atoll - with the 27th Infantry Division and on Tarawa - with the 2nd Marine Division.
M3 In the USSR
A story about the M3 tank would be incomplete without mentioning that these combat vehicles also came to the Soviet Union under the Lend-Lease program. True, the delivery figures are different: the American press reported about 1386 M3 sent to the USSR (it is not known how many of them reached their destination), but according to the Soviet archives, a little more than 900 vehicles were received. Soviet tankers did not like this bulky and, in comparison with domestic tanks, completely awkward in appearance. In the Red Army, the tank received the designation M3s ("s" - medium), but tankers with black soldier humor called it "a mass grave for seven." In general, the combat qualities of the tank, which were not high for 1942, were exacerbated by the inability to adapt to new operating conditions. On the Soviet-German front, M3s were used mainly in 1942, and then were replaced by Shermans.
DESIGN FEATURES
The M3 medium tank was created on the basis of the M2 tank, using almost all components and assemblies of the power plant, transmission and chassis of the latter. The hull was riveted, assembled from flat armor plates on a frame made of corners, and the front plates had relatively large angles of inclination, while the side ones were located vertically. The bow of the hull was cast, consisting of three parts, interconnected by bolts. The casting of the bow simultaneously served as the housing for the differential and final drives. Bolting made it easier to dismantle the bow to dismantle these units and the gearbox. For boarding and disembarking the crew, there were rectangular doors with hatches and viewing devices on the sides of the hull. The roof over the engine compartment was removable. In addition, to facilitate engine maintenance, a double hatch was provided in the aft hull sheet and a hatch in the bottom.
In the sponson, which was a special-shaped casting riveted to the frontal hull plates and the turret box, a 75-mm M2 gun was installed in the armor mask on the trunnions. This gun had ballistics and ammunition identical to the French 75 mm gun of 1897. The latter was adopted by the American army during the First World War. To arm the tank, the M3 cannon was also used, similar to the M2, but with a longer barrel, higher muzzle velocity and better armor-piercing characteristics of the shells. Since the installation of the gun was balanced based on the mass and dimensions of the M3, a counterweight had to be attached to the shorter M2 barrel. The gun was serviced by two crew members: a gunner and a loader. The sighting device for the 75 mm gun was an M21A1 telescopic sight mounted in an M1 periscope sight. A similar design was used on almost all American tanks during World War II. The horizontal pointing angle of the gun was 32 °, vertical -9 ... + 18 °.
A cast cylindrical turret was mounted on a ball bearing above the fighting compartment with an offset to the left from the longitudinal axis of the tank. A 37-mm M5 or M6 cannon, a 7.62-mm Browning M1919A4 machine gun paired with it, and an M2 periscope viewing device with a built-in M19A1 telescopic sight were mounted in the heavily sloping front of the turret. On the roof of the tower there was a commander's cupola with a Browning machine gun and a prismatic observation device. The elevation angle of the 37-mm cannon and machine gun in the commander's cupola reached 56°. Some of the guns had a guidance stabilizer in the vertical plane, to balance which a cylindrical counterweight was attached to the mask under the gun barrel.
In the control compartment of the tank in a fixed armored mask, two twin machine guns were mounted on a bracket. The bracket had a lever with which the elevation angle changed up to 9 °, declination - up to 4 °. Horizontal guidance was carried out by turning the tank. The fire control of machine guns was carried out by a driver. For this, the control levers were equipped with electric triggers.
The German blitzkrieg in France allowed the American generals to more or less soberly assess the deplorable state of their tank forces. It could be stated that at that time there were practically no tank forces in America, the tactics of using a few obsolete tanks was archaic, tank building vegetated for primitive level, and the design idea could not offer a single worthy project of a medium tank. The long economy of the American Congress on its army and the policy of isolationism bore their gloomy fruits. In order to urgently correct the dangerous situation on June 30, 1940, the American National Armaments Program was adopted, which, in particular, spoke of the need to produce 2000 medium tanks in the next 18 months. By the end of 1940, according to the plan, it was supposed to produce 14.5 tanks per day (8 vehicles for American customers and 6.5 for British). The next important step was the establishment in April 1941 of the Joint Tank Planning Committee, which raised the production rate to 1000 tanks per month, and by July they were already thinking about 2000 vehicles. After the meeting between Prime Minister Churchill, President Roosevelt and Lord Beaverbrook, the planned figures jumped to 25,000 medium tanks in 1942 and 45,000 tanks in 1943. However, the tank reform in America immediately ran into a lack of a medium tank that should have been produced.
In fact, the US had a new medium tank, the M2, standardized in August 1939. However, by the time the M2 tank was ready for mass production, its 37mm gun was already considered too weak for a vehicle of its class. On June 5, 1940, the Commander of the US Army Infantry Forces expressed the desire that medium tanks now be armed with 75mm guns. Therefore, as a temporary measure, from November 1939 to August 1940, only 92 M2A1 tanks were produced, which were immediately distributed among training and research centers. The weakness of M2A1 was too obvious, which was outdated before it appeared.
On June 13, 1940, the Artillery Department issued new requirements for a medium tank. On July 11, 1940, the tank was standardized as the Medium Tank M3 (medium tank M3). The urgent need for tanks forced the Americans to standardize and issue an order for production long before the finished design of the vehicle appeared.
To finally determine the characteristics of the future medium tank, the Commander of the Tank Forces, General Chaffee, on August 26, 1940, held a meeting at the Aberdeen Proving Ground with representatives of the Artillery Department and production workers who were part of the Tank Committee. By the way, the Tank Forces were established only a month and a half ago, on July 10, 1940. As a possible model, the meeting participants were shown a wooden model of a tank hull with a short-barreled 75mm T6 gun in the right sponson. It was a remake of an extremely unsuccessful anti-aircraft gun with a low muzzle velocity. Adapted for the tank, it received the designation T7, but in comparison with the weak 37mm gun of the M2A1 tank, it was a noticeable progress. During the consultations, it was finally decided that a modern medium tank should be armed with a 75mm gun. The catastrophic situation with the tanks required quick solutions, but the designers did not have a turret capable of receiving a 75mm cannon. Solely for the sake of gaining time, the US military agreed to not very a good option- install a 75mm gun in the sponson of a tank created on the basis of the M2A1. Moreover, one of the main requirements of the new project was the maximum technical similarity of the new machine with the M2A1. The military believed that such a machine would not last long in the army and would serve as a temporary measure until a tank with a 75mm gun in a full-rotation turret appeared. According to the military, about 360 M3 tanks were to be produced, until the time when the designers were able to develop a new tower. After that, the production of the M3 was supposed to be suspended and rebuilt for the production of a tank with a 75mm gun in the turret. Everyone agreed on this decision.
The development of a new machine was started by designers from Aberdeen. The basis for the project was the T5E2 prototype, which in turn was the T5 Phase III prototype, converted in March-May 1939 into a self-propelled gun with a 75mm M1A1 howitzer in the right front of the hull. The new tank had the same suspension as the M2 and a Wright R975 EC2 radial engine, 400 hp, but with a wider and longer hull. The rolled homogeneous armor of the new M3 tank was slightly enlarged and put on rivets inherited from the M2. Sponson, turret and commander's cupola - cast. Inside, the fighting compartment was pasted over with porous rubber to protect the crew from small secondary fragments and scale splashes that could occur when the projectile did not penetrate the tank's armor.
The engine was at the rear, and the transmission with synchronizer and differential at the front, under the protection of a three-piece armored cap, which was connected and bolted to the body. The transmission was located directly under the driver's seat, and was connected to the engine by a cardan shaft. Engine control rods went under the shaft. The Synchromesh gearbox had 5 forward gears and 1 reverse gear, with the following gear ratios:
1st gear - 7.56:1
2nd gear - 3.11:1
3rd gear - 1.78:1
4th gear - 1.11:1
5th gear - 0.73:1
rear - 5.65:1
The undercarriage consisted of three support bogies on board and a rubber-metal track. The bogie had two rubberized support rollers on a rocker arm, which was attached to a vertical spring in a welded frame. On top of the frame there was a roller that supported the caterpillar. Driving wheels with 13 teeth were in front.
The electrical system is 24 volts DC. There were two generators. The main generator was powered by a power take-off from the main engine and provided 24 volts, 50 amps. The spare generator was powered by the spare engine, producing 30 volts, 50 amps. In addition, there were two electric batteries of 12 volts.
The SCR 508 radio station was located to the left of the sponson, and the SCR 506 radio station was located to the right of the sponson in the command tanks, and the SCR 245 could be on the early commander's vehicles. For negotiations inside the tank, an interphone was used for 5 stations with headphones for each crew member.
In case of fire, the tank was equipped with two fixed 10-pound carbon dioxide fire extinguishers and two portable 4-pound fire extinguishers.
The first M3 pilot was armed with a 75mm T7 gun, 84 inches long, which was a modification of the 75mm T6 gun. The T7 had a vertical semi-automatic breech and could fire ammunition from a French WW1-M1897 gun borrowed by the Americans. The muzzle velocity of the T7 projectile reached 1850 feet per second. The T7 was standardized as the 75mm M2 gun. For balance, there was a counterweight in the front of the M2 barrel, and from the very beginning it was planned to replace the M2 with a longer gun in the future, so the counterweight was added not to the carriage, but to the barrel. The M2 gun was later replaced by the longer T8, standardized as the M3.
The cast turret was located on the left rear of the fighting compartment. She was armed with a 37mm M6 cannon and a coaxial machine gun. 30cal M1919A4. The tower had a manual and hydraulic rotary drive and made a full turn in 20 seconds. At the beginning of mass production, there were not always enough M6 guns, so 37mm M5 guns were sometimes put instead. The commander's cupola had another machine gun.30cal. Both tank guns - 37mm and 75mm were equipped with a gyro stabilizer in the vertical plane. In addition, two rigidly fixed .30cal machine guns were installed in the glacis, which were controlled by the driver. Ammunition load of 75mm guns was 65 rounds, 37mm guns - 126 rounds, 4000 rounds for machine guns, 20 magazines for machine guns, 6 hand grenades, 8 smoke grenades, 12 flares.
At first, the crew consisted of 7 people: the driver was in front, in the middle of the fighting compartment; radio operator - to the left and slightly behind the driver; gunner 75mm guns - on the right; loader - to the right of the gunner; commander - in the turret, behind; gunner - at the bottom of the tower, on the left; loader - below, on the right.
The crew could climb in and out of the car through two side doors (one per side), a hatch on top behind the 75mm cannon in the sponson and through a hatch in the commander's cupola.
All tankers had good review: driver's hatch and viewing holes, 2 viewing slots in the commander's cupola, 2 periscopes. The tank had 4 pistol embrasures: one near the driver, one on each door, one behind and one on the left of the turret.
The weight of the machine was about 31 tons.
It should be noted that the creation of an acceptable medium tank project was only part of the solution to the huge problem of mass tank building. America met the beginning of WW2 not only without a normal medium tank, but also without production facilities capable of producing it in large quantities. At that time, only one small state-owned enterprise, Rock Island Arsenal, was responsible for the production of American tanks. Naturally, it was not necessary to seriously count on him, therefore, it was necessary to urgently reform the country's production potential. Responsible for coordinating American industry and defense needs was William S. Knudsen, member of the National Defense Advisory Committee and president of the General Motors Corporation. To increase production, it was necessary to attract private contractors, but serious disagreements arose here. The Artillery Department believed that heavy engineering enterprises, which had previously specialized in the production of locomotives and large cranes, should receive the main contracts. However, Knudsen took the exact opposite view. He was convinced that although heavy engineering enterprises have sufficient potential, the specifics of their production lies in the relatively long and small-scale production of products. At the same time, the newly emerging Tank Forces demanded urgent mass deliveries of armored vehicles. Based on this, Knudsen insisted that tank building should be taken up by automotive companies that were accustomed to producing products quickly and in large quantities. He put forward a proposal to urgently build a specialized tank plant in Michigan on the basis that Chrysler takes on half the costs, and the state takes the other half. The Arsenal was to be owned by the state and run by Chrysler. This idea found understanding among the authorities and the president of the Chrysler Corporation - Keller. On August 15, 1940, Chrysler received a contract for 1,000 M2A1 medium tanks. In September 1940, construction began on a new factory in Warren, north of Detroit, on a 100-square-acre site. The building originally measured 1,380 x 500 feet and was designed by architect Albert Kahn in the Art Nouveau style.
Meanwhile, the Ordnance Department signed contracts with two of the largest heavy engineering companies - the American Locomotive Company for 685 tanks and the Baldwin Locomotive Company for 535 tanks. Rock Island Arsenal was constantly communicating with them so that contractors could immediately start production when the design of the tank was ready.
During the design work on the future M3 tank, Rock Island Arsenal worked closely with Chrysler to ensure that the equipment of the plant under construction corresponded to the technology of the future tank. In addition, Rock Island Arsenal was in constant consultation with other contractors. In addition, in June 1940, the British Tank Commission headed by Michael Devor arrived in the United States. The British, having lost a significant part of their tank forces in France, were very interested in acquiring American tanks and willingly shared their combat experience with the M3 developers.
In February 1941, the tank project was generally ready, and the plant in Michigan was almost completed.
March 13, 1941 Rock Island Arsenal completed the first pilot of the future tank, and on March 21 the prototype was delivered to the Aberdeen Proving Ground. In April 1941, three contracting firms finished their template pilots of the M3 tank and they gradually arrived at the training ground. In August 1941, one prototype was sent from Aberdeen to the Panzer Troops at Fort Bening and two more were handed over to the British. Tanks were shipped to England on September 20, 1941 by Lend Lease. It is noteworthy that at that time many M3 tanks supplied to the Tank Forces did not have 75mm guns.
Based on the feedback from the British and their military, a number of serious flaws were identified in the design of the tank.
Hycon hydraulics in the steering system proved too unreliable. The first M3s were equipped with a Hycon hydraulic system, but on 26 August 1942 the Detroit Tank Arsenal switched to a fully mechanical system. In February 1942, the Ordnance Department recommended that all manufacturers switch from hydraulic to mechanical variant.
Tests in Aberdeen stated a strong gas contamination of the fighting compartment with carbon monoxide, when firing with closed hatches. To solve the problem, new fans were installed in the tank: on the roof of the turret, on the roof to the left of the driver, in the hatch above the 75mm gun. Soon the fan in the hatch above the 75mm cannon was moved behind the hatch for convenience.
Another drawback was the weak VSS suspension borrowed from the M2 tank. To prevent the suspension from spoiling quickly, the springs were reinforced in it. The support roller has been moved back.
Ballistic tests showed that both cannons could be jammed by enemy small arms fire. The designers developed additional protective shields, which, however, were rarely installed.
It turned out that the side doors were too vulnerable to shelling, not only armor-piercing, but also high-explosive shells. Specialists from Aberdeen recommended removing the doors and making an escape hatch in the floor. The hatch in the floor in the right rear of the fighting compartment appeared on later tank models.
But the power drive for turning the tower and the gyro stabilizer in the vertical plane showed their best side. With the tank moving in zigzags at 10 miles per hour, the gunner easily acquired targets at a distance of 200-700 yards in any direction. Based on test results, the Ordnance Department in June 1941 recommended standardizing stabilizers for 75mm and 37mm guns. By November 1941, the Detroit Tank Arsenal began to install stabilizers on production vehicles, and from January this innovation was to be installed by all M3 manufacturers.
In the engine compartment, they put a box on the sides. The radio operator was removed from the crew, and his duties were transferred to the driver. In June 1942, the Artillery Committee advised that both driver's fixed course machine guns should be abandoned; two machine guns and one of two .45cal submachine guns. The constructors agreed to remove only one course machine gun and one machine gun. Later, during serial production, the pistol loopholes were removed on the left side, but left on the right.
Over time, the tankers accumulated dissatisfaction with the fact that the periscope sight did not provide sufficient accuracy for the 75mm gun. Instead of a periscope, they put a telescopic sight.
By August 1941, finally, began a full-scale serial production M3 tanks at three enterprises. Rock Island Arsenal did not participate in the release of M3. On August 28, 1940, the production of the M2A1 medium tank, the predecessor of the M3, was finally curtailed.
Chrysler produced 3352 tanks,
American Locomotive Company - 685,
Baldwin Locomotive Company - 1220,
Pressed Steel Car Company - 501
Pullman Standard Car Company - 500
The average cost of an M3 series tank was $55,244.

The British, who bought tanks of the M3 series, gave him two names, depending on the British or English modification of the vehicle:
M3 Grant (M3 Grant) for the British modification
M3 Lee (M3 Lee) - for the American version.
In October 1941, a new M4 medium tank was standardized in the USA, and the M3 became the "substituted standard" (replaced standard). In April 1943, the M3 was already a "limited standard", and a year later, in April 1944, the M3 was declared obsolete.

modifications of the M3 tank
All later models of tanks, regardless of modification, had a longer 75mm M3 gun.
M3. Riveted hull, cast turret, side doors, Wright Continental R-975 radial engine, 340hp It was produced from April-August 1941 to August 1942. A total of 4,924 M3 tanks were manufactured.
Detroit Tank Arsenal produced 3,242 M3 tanks
American Locomotive Company - 385
Baldwin Locomotive Company - 295
Pressed Steel - 501
Pullman-500.
Some cars, due to a shortage of Continental engines, were equipped with Guiberson diesel engines, and "(Diesel)" was added to the name of the modification.
М3А1. The successful service of cast towers made us think about a cast hull. Ballistic tests showed satisfactory results for cast armor, although it had to be made thicker to achieve the strength of rolled homogeneous armor. The somewhat greater weight of the cast hull was fully compensated by a smoother surface and the absence of rivets so unloved by tankers. In June 1941, the Artillery Committee authorized the production of a cast upper hull. The lower part remained riveted. October 9, 1941 this version of the tank received the name M3A1. The mechanics of the M3A1 is identical to the M3 tank. The upper hatch on the right side of the hull roof was different. At the cast hull, the hatch was on a plane tilted back, and the hatch fastening loops were in front. To make the hatch easier to open, the hatch hinges were moved back on later machines. Also on late models there were no side doors, and an escape hatch was added in the floor on the right rear. The pistol embrasure on the rear wall of the fighting compartment was removed.
М3А1 was produced by American Locomotive Company in February-August 1942. 300 pieces were produced.
From July 2 to October 8, 1941, the Guberson T-1400-2 diesel engine was tested in Aberdeen for the M3A1 series tank. This tank was sent as a sample for production, and instead continued testing with another M3A1. April 30, 1942 the first tank was returned to Aberdeen and tested until June 23, 1942. Then the engine was dismantled and inspected. Although the tank's range almost doubled, the Guberson T-1400-2 required frequent repairs and proved to be unreliable. Aberdeen did not recommend the use of this engine and offered to continue to refine it. A decree was issued that Guberson should be abandoned as soon as other engines become available. For this reason, the American Locomotive Company produced only 28 M3A1s with the Guberson T-1400-2. These cars had in the name - "(Diesel)".
M3A2. The mechanics are identical to the M3. The entire hull was welded, which met the new requirement of the Ordnance Department of September 1941. Ballistic tests showed that the welded hull, with slightly less weight, provided better protection than the riveted one. Even when the shell did not penetrate the armor, rivets flew dangerously inside the tank. A welded hull was cheaper and assembled faster. The Baldwin Locomotive Company began production in January 1942, but in March, when 12 cars were produced, a new engine was adopted.
M3A3. Due to the fact that the Continental air-cooled engine was required not only for tank building, but also for aviation, there was a shortage of engines for the M3. In August 1941, a successful attempt was made to install in the M3 a block of two conventional General Motors 6-71, 375hp diesel automobile engines. The new power plant was named Model 6046. Each motor in the block worked independently and could independently move the tank if necessary. The new engine took up more space than the radial, so to protect the radiators installed at the rear, it was necessary to increase the aft and side armor down to the level of the tracks, and the rear foxes were tilted 10 degrees from the vertical. The rear one-piece armor plate replaced the access doors to the engine compartment. Since the air flow and exhaust gases were now raising a lot of dust from the ground, reflectors had to be installed. Cooling air entered through two louvered hatches above the engine compartment. The larger size of the new engine forced the engine compartment to be enlarged by 12 inches at the expense of the fighting compartment. The efficiency of the diesel has reduced the fuel capacity to 148 gallons, while the range has increased to approximately 160 miles. The new diesel engine was tested on the M3 tank with serial number 28 from the Detroit Tank Arsenal. In October 1941, a new engine was approved as an alternative to the Continental R-975. The diesel engine dramatically reduced the fire hazard associated with the Continental R-975 aircraft, which ran on 92 octane gasoline.
Initially, the Artillery Committee standardized the diesel-powered tank as the M3A3, but then only vehicles with a welded hull fell under this designation.
The tank has a welded hull. On later models, the side doors are welded or missing. Weight increased to 28,600kg, top speed increased to 29 mph (about 47 km/h). From January to December 1941, the Baldwin Locomotive Company produced 322 tanks.
M3A4. Worried about the lack of engines, William Knudsen commissioned Chrysler to develop a new engine that could be quickly brought into production using existing production capacity. November 15, 1941 the first trial engine was installed on the M3. It was the Chrysler A-57 Multibank, a multiblock of five 6-cylinder car engines connected in a star configuration, with a total power of 425 hp. at 2850 rpm. To accommodate the power multiblock, the engine compartment had to be lengthened by 11 inches, while the rear upper armor plates of the hull were pushed back by 15 inches. The entire multiblock was cooled by a single radiator at the top rear of the engine compartment. The two vertical fuel tanks had to be removed, but instead each of the two tanks in the sponsons was increased to 80 gallons. The new longer hull forced the middle and rear bogies with road wheels to be moved back. The distance between them increased by 6 inches, and the track was lengthened from 79 to 83 tracks. The weight of the tank has increased to 29,000kg. There were no side doors, there were three fans on the roof, and the supporting rollers, which used to be in the middle at the top of the frame of the wheel pair support bogies, were moved back behind the bogies.
In December 1941 the Artillery Committee standardized the tank as the M3A4.
In February 1942, the M3A4 was delivered to the Aberdeen Proving Ground for testing. After 42 hours of operation on different types of roads, the engine was replaced with a serial one and tests continued. In total, until October 1942, three engines were tested, and the test results influenced changes in serial samples.
In June-August 1942, the Detroit Tank Arsenal produced 109 M3A4 tanks, after which it switched to the assembly of M4A4 medium tanks. On the new tank, this company installed a multiblock engine from the M3A4.
M3A5. Identical to the M3A3 modification, but with a riveted hull instead of a welded one. The side doors were welded on or removed on later machines. In January-November 1942, the Baldwin Locomotive Company produced 591 tanks.
special purpose vehicles based on M3 series tanks
Mine Exploder T1 (for M3 Medium Tank)- trawl to undermine mines. It consisted of two rollers attached to the front of the tank and one to the rear. Initially, a mine sweep was developed for the M2A1 at the beginning of 1942. In practice, it turned out to be unsuccessful.
M3 with E3 Flame gun- instead of a 37mm gun, a flamethrower was installed, and a 75mm gun was dismantled. Initially, the E2 flamethrower was developed for the M2 medium tank. Development did not progress beyond testing.
M3 with E5R2-M3 Flame gun- a portable flamethrower for quick installation in the field instead of a machine gun in the commander's cupola. Initially, the flamethrower was designed to be placed in a ball mount of a kuros machine gun on an M3A1 light tank. A container for 10 gallons of flammable liquid was inside the tank. This flamethrower could also be installed in the M5 light tank.
Shop Tractor T10- British CDL tank made in the USA. In May-December 1943, the American Locomotive Company converted 355 M3A1 tanks. They did not participate in the battles.
Heavy Tractor T16- M3 converted into an artillery tractor. The turret and sponson were dismantled, and a winch was added at the rear to tow the gun. In early 1942, tests showed that there was little room in the car for artillery crews and ammunition. The project did not progress beyond the prototype.
Tank Recovery Vehicle T2 (M31)- BREM based on the standard M3. The armament was dismantled, replaced with dummies of trunks, a winch, a crane boom and tool boxes were installed at the back. In September 1942 it was produced as "limited procuremet" (limited production), and in December 1943 it was renamed to M31 and standardized as "limited standard" (limited fit). ARVs converted from M3A3 tanks were called M31 B1, and M3A5 conversions were called M31V2.
Full Track Pime Mover M33- tractor for 155mm guns. Converted from M31 ARV in 1943-44. The turret and crane were removed, but an air compressor and hoses were added to connect to the brake system on the artillery carriage of the towed gun. A .50cal anti-aircraft machine gun was installed on the roof of the tractor hull. The pilot was called T1.
There was a similar tractor - Tractor 44, which was distinguished by a commander's cupola on the sponson.
3in Gun Motor Carriage T24- an attempt to convert the M3 tank into a tank destroyer with a 3-inch (76mm) gun. The turret, sponson and hull roof were removed from the M3 tank, but the vehicle turned out to be too high and complex for rapid mass production. The development of the T24 began in September 1941, and in March 1942 the project was closed.
3in Gun Motor Carriage T40 (M9)- an attempt to install a decommissioned anti-aircraft 3-inch M1918 gun on the T24 GMC. Since only 50 guns were available, in December 1941 it was proposed to manufacture only 50 of these tank destroyers. In April 1942 the car was standardized as the M9 GMC "limited standard" (limited fit) and an order was issued for the production of 50 pieces. In addition, only 28 obsolete anti-aircraft guns remained in stock, and even before the final fulfillment of the order for the M9 GMC, the industry mastered more modern fighter tanks M10 GMC. As a consequence, the M9 GMC was abandoned in August 1942.
40mm Gun Motor Carriage T36- a project of an anti-aircraft installation with a 40mm gun on the M3 chassis. It was created at the suggestion of the Air Defense Directorate, published in October-November 1941. The vehicle turned out to be too weakly armed and difficult to manufacture, so the project was closed.
experimental vehicles based on the M3 tank
M3E1. The M3 tank was actively used to test various components before being installed on the M4, with a technically similar design. Since one of the main problems of American medium tanks was the frequent shortage of engines, they decided to test the Sherman engine on the M3. For installation in the tank, they adapted a Ford aircraft engine, liquid-cooled, V12. After the modification, the number of cylinders was reduced to 8, and the power was 50hp. at 2600 rpm. On December 19, 1942, the Artillery Committee assigned the designation M3E1 to the M3 tank with the tested engine. Tests in Aberdeen were successful and the engine adopted for service began to be installed on M4A3 tanks. A 4-stroke Ford GAA, V8, with a volume of 18 cubic liters, provided a normal power of 450 hp. at 2600 rpm and a maximum of 500 hp. at 2600 rpm.
M3A5E1. Specialists from the Aberdeen Proving Ground recommended installing automatic transmissions on medium tanks. In early January 1942, such a machine appeared, which received the designation M3A5E1. The prototype had a twin General Motors diesel engine and two Hydramatic hydraulic transmissions. Tests in Aberdeen showed the advantages of the M3A5E1 over the M3 and M3A5 tanks. The new transmission provided greater acceleration, better driving comfort and greater gun platform stability.
As a result, the M3A5E2 tank appeared with one powerful Hydramatic transmission.
Tank M3 with serial number 935 used for suspension tests. The M3 and M4 initially used a reliable VVSS scheme with a vertical suspension spring. However, at high speed, the ride became very stiff, so the spring in the support cart was placed horizontally, which allowed the use of shock absorbers. The scheme with a horizontal spring was called HVSS and began to be installed on tanks of the M4 series.
In addition, experiments were carried out with a change in the sloth, to increase the contact of the caterpillar with the ground and, accordingly, reduce the specific pressure of the tank on the ground. The project did not progress beyond testing.
M3A1E1. The constant shortage of engines for medium tanks led to the creation of the Lycoming T1300 engine, which consisted of three 6-cylinder engines in a single block, with a total volume of 1300 cubic inches and an output of 560 hp. For testing, this multiblock was installed on the M3A1 tank with serial number 1986. In February 1942, the prototype was named M3A1E1. Tests showed that the Lycoming T1300 provided the highest speed at that time - 40 miles / hour. Nevertheless, the power plant turned out to be very complex and extremely inconvenient, for example, the engine had to be dismantled to replace the spark plug. When the tests came to an end, other engines were already available, so the project was closed.
M3 and Lend-Lease
Almost two-thirds of the M3 Lee produced by the Americans were sent under Lend-Lease to Great Britain and the USSR. The Soviet Union received 812 M3 Li in 1942 and 164 tanks in 1943. It is worth noting that in 1943, 12 M3s tanks were raised from a sunken transport in the Arctic Ocean, after which one tank was dismantled for spare parts and 11 entered the troops of the Karelian Front. Tanks raised from the bottom of the sea did not appear in any way in the Soviet documents of the selection committees of the GBTU KA. Together with these machines, in 1943 the USSR received 175 M3 Li. In total, out of 1,386 sent M3 tanks, the Land of Soviets received 976 vehicles, and in 1942 several M2 tanks arrived under the M3 brand.
In 1942-43, American M3 Lee tanks were actively used on almost all fronts as part of separate tank battalions, regiments and brigades. The culmination of the combat use of the M3 Lee came in the summer-autumn of 1942. The M3 Lee also took part in the legendary tank battle near Kursk. On July 1, 1943, the 48th A of the Central Front had 83 of these tanks: 30 in the 45th separate tank regiment in the Saburov area and 55 M3 in the 193rd separate tank regiment near Petrovka. One M3 Lee participated in the war with Japan as part of the Trans-Baikal Front.
Tanks raised from the bottom of the Arctic Ocean, after a year spent under water, were repaired and sent to the 91st separate tank regiment of the 14th Army of the Karelian Front.
The Americans sent 2,653 M3, 49 M3A3, 185 M3A5 tanks to the UK.
In addition, America sent 77 М3А3, 23 М3А5 to other countries.
