SU-100 - Soviet self-propelled guns of the period of the Second World War, belongs to the class of tank destroyers, medium in weight. The self-propelled gun was created on the basis of the T-34-85 medium tank by the designers of Uralmashzavod in late 1943 and early 1944. At its core, it is a further development of the SU-85 self-propelled guns. It was developed to replace the SU-85, which had insufficient ability to deal with German heavy tanks. Serial production of the SU-100 self-propelled guns began at Uralmashzavod in August 1944 and continued until March 1946. In addition, from 1951 to 1956, the self-propelled guns were produced in Czechoslovakia under license. In total, according to various sources, from 4,772 to 4,976 self-propelled guns of this type were produced in the USSR and Czechoslovakia.

By the middle of 1944, it became completely clear that the means of combating modern German tanks available to the Red Army were clearly not enough. It was necessary to qualitatively strengthen the armored forces. They tried to solve this issue by using a 100-mm gun with the ballistics of the B-34 naval gun on the self-propelled guns. The draft design of the vehicle was presented to the People's Commissariat of Tank Industry in December 1943, and already on December 27, 1943, the GKO decided to adopt a new medium self-propelled gun armed with a 100-mm gun. The place of production of the new self-propelled gun was determined by "Uralmashzavod".

The development deadlines were very tight, however, having received the drawings of the S-34 gun, the factory was convinced that this gun was not suitable for self-propelled guns: it has very impressive dimensions, and when pointing to the left it rests on the second suspension, not allowing it to be placed on the former place the driver's hatch. In order to install this gun on a self-propelled gun, serious changes in its design were required, including its sealed hull. All this entailed a change in production lines, a displacement of the driver's workplace and controls by 100 mm. to the left and changing the suspension. The weight of the self-propelled guns could increase by 3.5 tons compared to the SU-85.

In order to cope with the problem that had arisen, Uralmashzavod turned to plant No. 9 for help, in which, at the end of February 1944, under the guidance of designer F.F. Petrov, a 100-mm D-10S gun was created, developed on the basis of a naval anti-aircraft gun B-34. The created gun had a lower mass in comparison with the S-34 and was freely mounted in a serial self-propelled gun body without any significant changes and an increase in the mass of the machine. Already on March 3, 1944, the first prototype of the new self-propelled gun, armed with the new D-10S gun, was sent for factory testing.

The performance characteristics of the new SU-100 self-propelled guns allowed it to successfully fight modern German tanks at a distance of 1500 meters for Tigers and Panthers, regardless of the point of impact of the projectile. Self-propelled guns "Ferdinand" could be hit from a distance of 2000 meters, but only if it hit the side armor. The SU-100 possessed exceptional firepower for Soviet armored vehicles. Her armor-piercing projectile at a distance of 2000 meters pierced 125 mm. vertical armor, and at a distance of up to 1000 meters it pierced most German armored vehicles almost through and through.

Design features

The SU-100 self-propelled guns were designed on the basis of the units of the T-34-85 tank and the SU-85 self-propelled guns. All the main components of the tank - chassis, transmission, engine were used unchanged. The thickness of the front armor of the cabin was almost doubled (from 45 mm for the SU-85 to 75 mm for the SU-100). The increase in armor, combined with an increase in the mass of the gun, led to the fact that the suspension of the front rollers was overloaded. They tried to solve the problem by increasing the diameter of the spring wire from 30 to 34 mm, but it was not possible to completely eliminate it. This problem reflected the constructive heritage of the backward suspension of the Christie tank.

The body of the self-propelled gun, borrowed from the SU-85, has undergone, albeit a few, but very important changes. In addition to an increase in frontal armor, a commander's cupola with MK-IV viewing devices (a copy of the British ones) appeared on the self-propelled guns. Also, 2 fans were installed on the machine for better cleaning of the fighting compartment from powder gases. In general, 72% of the parts were borrowed from the T-34 medium tank, 7.5% from the SU-85 self-propelled guns, 4% from the SU-122 self-propelled guns, and 16.5% were redesigned.

The SU-100 self-propelled guns had a classic layout for Soviet self-propelled guns. The fighting compartment, which was combined with the control compartment, was located in front of the hull, in a fully armored conning tower. Here were located the controls for the mechanisms of the self-propelled guns, the main armament complex with sights, the gun ammunition, the tank intercom (TPU-3-BisF), and the radio station (9RS or 9RM). The bow fuel tanks and part of the useful tool and spare parts (SPTA) were also located here.

In front, in the left corner of the cabin, there was a driver’s workplace, opposite which there was a rectangular hatch in the frontal hull plate. In the cover of its hatch, 2 prismatic viewing devices were mounted. To the right of the gun was the seat of the vehicle commander. Immediately behind the driver's seat was the gunner's seat, and in the left rear corner of the conning tower, the loader. In the roof of the cabin there were 2 rectangular hatches for the landing / disembarkation of the crew, a fixed commander's cupola and 2 fans under the caps. The commander's turret had 5 viewing slots with armored glass, the MK-IV periscope viewing devices were located in the hatch cover of the commander's turret and the left wing of the gunner's hatch cover.

The engine compartment was located immediately behind the combat and was separated from it by a special partition. In the middle of the MTO, a V-2-34 diesel engine was mounted on a sub-frame, developing a power of 520 hp. With this engine, the self-propelled guns weighing 31.6 tons could accelerate on the highway up to 50 km / h. The transmission compartment was located in the stern of the self-propelled gun body, there were the main and onboard clutches with brakes, a 5-speed gearbox, 2 inertia-oil air cleaners and 2 fuel tanks. The capacity of the internal fuel tanks of the self-propelled guns SU-100 was 400 liters, this amount of fuel was enough to make a 310-km march along the highway.

The main armament of the self-propelled gun was a 100-mm rifled gun D-10S mod. 1944. The length of the gun barrel was 56 calibers (5608 mm). The initial velocity of the armor-piercing projectile was 897 m/s, and the maximum muzzle energy was 6.36 MJ. The gun was equipped with a semi-automatic horizontal wedge gate, as well as mechanical and electromagnetic descent. To ensure smooth aiming in the vertical plane, the gun was equipped with a compensating spring-type mechanism. The recoil devices consisted of a hydropneumatic knurler and a hydraulic recoil brake, which were located above the gun barrel on the right and left, respectively. The total mass of the gun and recoil mechanisms was 1435 kg. The SU-100 self-propelled guns included 33 unitary shots with BR-412 armor-piercing tracer and OF-412 high-explosive fragmentation rounds.

The gun was installed in the frontal slab of the cabin in a special cast frame on double trunnions. Pointing angles in the vertical plane ranged from -3 to +20 degrees, in the horizontal 16 degrees (8 in each direction). The aiming of the gun on the target was carried out using two manual mechanisms - a rotary screw-type mechanism and a sector-type lifting mechanism. When firing from closed positions, the Hertz panorama and the side level were used to aim the guns; when firing direct fire, the gunner used the TSh-19 telescopic articulated sight, which had a 4x magnification and a field of view of 16 degrees. The technical rate of fire of the gun was 4-6 rounds per minute.

Combat use

The SU-100 self-propelled guns began to enter the troops in November 1944. In December 1944, the troops began to form 3 separate self-propelled artillery brigades of the RGVK, each of which consisted of 3 regiments armed with SU-100 self-propelled guns. The staff of the brigade included 65 self-propelled guns SU-100, 3 self-propelled guns SU-76 and 1492 people of the average composition. The brigades, which received the numbers 207th Leningradskaya, 208th Dvinskaya and 209th, were created on the basis of existing separate tank brigades. In early February 1945, all the formed brigades were transferred to the fronts.

Thus, brigades and regiments armed with SU-100 self-propelled guns took part in the final battles of the Great Patriotic War, as well as in the defeat of the Japanese Kwantung Army. The inclusion of ACS data in the advancing mobile groups significantly increased their strike power. Often SU-100s were used to complete the breakthrough of the tactical depth of the German defense. The nature of the battle at the same time was similar to an attack on the enemy hastily prepared for defense. The preparation of the offensive took a limited time or was not carried out at all.

However, the SU-100 self-propelled guns had a chance not only to advance. In March 1945, they took part in defensive battles near Lake Balaton. Here, as part of the troops of the 3rd Ukrainian Front, from March 6 to March 16, they participated in repelling the counterattack of the 6th SS Panzer Army. All 3 brigades formed in December 1944, armed with SU-100s, were brought in to repel a counterattack, and separate self-propelled artillery regiments armed with SU-85 and SU-100 self-propelled guns were also used in defense.

In the battles from March 11 to March 12, these self-propelled guns were often used as tanks, due to the large losses of armored vehicles. Therefore, an order was given along the front to equip all self-propelled guns with light machine guns for better self-defense. Following the results of the March defensive battles in Hungary, the SU-100 earned a very flattering assessment of the Soviet command.

Without a doubt, the SU-100 self-propelled guns were the most successful and powerful Soviet anti-tank self-propelled guns of the Great Patriotic War period. The SU-100 was 15 tons lighter and at the same time had comparable armor protection and better mobility in comparison with the identical German Jagdpanther tank destroyer. At the same time, the German self-propelled guns, armed with the 88-mm German cannon Pak 43/3, surpassed the Soviet one in terms of armor penetration and the size of the ammo rack. The Jagdpanther gun, due to the use of a more powerful PzGr 39/43 projectile with a ballistic tip, had better armor penetration at long distances. A similar Soviet projectile BR-412D was developed in the USSR only after the end of the war. Unlike the German tank destroyer, the SU-100 had no cumulative and sub-caliber ammunition in its ammunition load. At the same time, the high-explosive fragmentation action of a 100-mm projectile was naturally higher than that of a German self-propelled gun. In general, both of the best medium anti-tank self-propelled guns of the Second World War did not have any outstanding advantages, despite the fact that the possibilities of using the SU-100 were somewhat wider.

The SU-100-Y is an experimental heavy Soviet self-propelled gun based on the T-100 tank, produced in a single copy in 1940.

The history of the creation of the SU-100U

Even during the Winter War, the Red Army felt an urgent need for armored engineering vehicles. In 1939, it was decided to create an engineering tank based on the T-100 with anti-ballistic armor to carry explosives and sappers, build a bridge, evacuate damaged tanks, and perform other similar tasks.

During the design, an order was received - they demanded to put a cannon on the T-100 base in order to fight the enemy fortifications. As a result, the plant was asked to change plans, that is, to start designing not an engineering vehicle, but self-propelled guns. Permission was obtained, and in January 1940, the drawings of the T-100-X, the prototype of the SU-100-Y, were transferred to the Izhora plant.

During the manufacture of the machine, the cabin was replaced with a simpler one in order to speed up assembly, and by March 1940, the SU-100-Y or T-100-Y, as it was also called, went to the first exit.

Use in combat

In March 1940, the SU-100-Y was sent to Karelia, but by that time the fighting there had already ended, and it was not possible to test the car in combat conditions. Self-propelled fired at the defensive lines of the Finns. The machine performed well, but due to its large mass and size, it was too difficult to transport it by rail.

When the KV-1 and KV-2 were put into service, all work on machines based on the T-100 was completed. In the summer of 1940, the self-propelled gun was transferred to Kubinka, and in 1941 it participated in the defense of Moscow along with the SU-14-1 and SU-14. There is no other information about the use of the SU-100-Y.

tank memory

The SU-100-Y, unlike its base, the T-100, is today preserved and exhibited in the museum in Kubinka.

More powerful than the SU-85 self-propelled artillery mount. In 1944, such an installation was put into service under the name "SU-100". To create it, the engine, transmission, chassis and many components of the T-34-85 tank were used. The armament consisted of a 100 mm D-10S cannon mounted in a wheelhouse of the same design as the SU-85 wheelhouse. The only difference was the installation on the SU-100 on the right, in front, of a commander's cupola with observation devices for the battlefield. The choice of gun for arming the self-propelled gun proved to be very successful: it perfectly combined rate of fire, high muzzle velocity, range and accuracy. It was perfect for fighting enemy tanks: its armor-piercing projectile pierced 160-mm thick armor from a distance of 1000 meters. After the war, this gun was installed on new T-54 tanks.
Just like the SU-85, the SU-100 was equipped with panoramic tank and artillery sights, a 9R or 9RS radio station, and a TPU-3-BisF tank intercom. The SU-100 self-propelled unit was produced from 1944 to 1947, during the Great Patriotic War 2495 units of this type were produced.

The self-propelled artillery mount SU-100 ("Object 138") was developed in 1944 by the UZTM design bureau (Uralmashzavod) under the general supervision of L.I. Gorlitsky. The leading engineer of the machine was G.S. Efimov. During the development period, the self-propelled unit had the designation "Object 138". The first prototype of the unit was produced at UZTM together with plant No. 50 NKTP in February 1944. The machine passed factory and field tests at the Gorohovets ANIOP in March 1944. Based on the test results in May - June 1944, a second prototype was made, which became the prototype for serial production. Serial production was organized at UZTM from September 1944 to October 1945. During the Great Patriotic War from September 1944 to June 1, 1945, there were 1,560 self-propelled guns that were widely used in battles at the final stage of the war. A total of 2,495 SU-100 self-propelled guns were produced during serial production.

self-propelled installation The SU-100 was created on the basis of the T-34-85 medium tank and was intended to fight the German heavy tanks T-VI "Tiger I" and T-V "Panther". It belonged to the type of closed self-propelled units. The layout of the installation was borrowed from the self-propelled gun SU-85. In the control compartments in the bow of the hull on the left was the driver. In the fighting compartment, the gunner was located to the left of the gun, and the vehicle commander was to the right. The loader's seat was located behind the gunner's seat. Unlike the previous model, the working conditions of the vehicle commander were significantly improved, the workplace of which was equipped in a small sponson on the starboard side of the fighting compartment.

On the roof of the cabin above the commander's seat, a fixed commander's cupola was installed with five viewing slots for all-round visibility. The hatch cover of the commander's turret with a built-in viewing device MK-4 rotated on a ball chase. In addition, a hatch was made in the roof of the fighting compartment for setting the panorama, which was closed with double-leaf covers. An MK-4 viewing device was installed in the left hatch cover. There was a viewing slot in the stern leaf of the felling.

The driver's workplace was in front of the hull and was shifted to the port side. The layout feature of the control compartment was the location of the gear lever in front of the driver's seat. The crew boarded the car through a hatch in the rear of the roof of the cabin (on the cars of the first releases - double-leaf, located in the roof and aft sheet of the armored cabin), the hatches of the commander and the driver. The landing hatch was located on the bottom of the hull in the fighting compartment on the right side of the vehicle. The manhole cover opened down. For ventilation of the fighting compartment, two exhaust fans were installed in the roof of the cabin, covered with armored caps.

The engine compartment was located behind the combat and was separated from it by a partition. In the middle of the engine compartment, an engine with the systems that provided it was installed on a sub-engine frame. On both sides of the engine, two radiators of the cooling system were located at an angle, an oil cooler was mounted on the left radiator. On the sides, one oil cooler and one fuel tank were installed. Four batteries were installed on the bottom in racks on both sides of the engine.

The transmission compartment was located in the aft part of the hull, it housed the transmission units, as well as two fuel tanks, two Multicyclone type air cleaners and a starter with a starting relay.

The main weapon of the self-propelled gun was the 100 mm D-100 mod. 1944, mounted in a frame. The barrel length was 56 calibers. The gun had a horizontal wedge gate with semi-automatic mechanical type and was equipped with electromagnetic and mechanical (manual) descents. The electric shutter button was located on the handle of the lifting mechanism. The swinging part of the cannon had a natural balance. Vertical aiming angles ranged from -3 to + 20 °, horizontal - in the 16 ° sector. The lifting mechanism of the gun is of a sector type with a donating link, the swivel mechanism is of a screw type. When firing direct fire, a telescopic articulated sight TSh-19 was used, when firing from closed positions, a Hertz gun panorama and a side level. The direct fire range was 4600 m, the maximum - 15400 m.

The ammunition of the installation included 33 unitary shots with an armor-piercing tracer (BR-412 and BR-412B), a fragmentation-sea grenade (0-412) and a high-explosive fragmentation grenade (OF-412). The initial speed of an armor-piercing projectile weighing 15.88 kg was 900 m/s. The design of this gun, developed by the design bureau of plant No. 9 NKV under the leadership of F.F. Petrov, turned out to be so successful that for over 40 years it was installed on serial post-war tanks T-54 and T-55 of various modifications. Additionally, two 7.62-mm PPSh submachine guns with 1420 rounds of ammunition (20 discs), 4 anti-tank grenades and 24 F-1 hand grenades were placed in the fighting compartment.

Armor protection - protivosnaryadnaya. The armored body is welded, made of rolled armor plates 20 mm, 45 mm and 75 mm thick. Frontal armor plate with a thickness of 75 mm with an angle of inclination of 50° from the vertical was aligned with the front plate of the cabin. The gun mask had armor protection 110 mm thick. In the frontal, right and aft sheets of the armored cabin there were holes for firing from personal weapons, which were closed with armor plugs. In the course of mass production, the nose beam was eliminated, the connection of the front fender liner with the front plate was transferred to the "quarter" connection, and the front fender liner with the aft plate of the armored cabin - from "studded" to "butt" connection. The connection between the commander's cupola and the cabin roof was reinforced with a special collar. In addition, a number of critical welds were transferred to welding with austenitic electrodes.

In all other respects, the design of the SPG hull was similar to the SU-85 hull, with the exception of the roof structure and aft vertical sheet of the armored cabin, as well as individual engine compartment roof hatches.

To set up a smoke screen on the battlefield, two MDSH smoke bombs were installed at the stern of the vehicle. The ignition of the smoke bombs was carried out by the loader by turning on two toggle switches on the MDS panel mounted on the engine bulkhead.

The design and layout of the power plant, transmission and chassis were basically the same as on the T-34-85 tank. A four-stroke twelve-cylinder V-shaped V-2-34 diesel engine with an HP 500 power was installed in the engine compartment at the rear of the car. (368 kW). The engine was started using a ST-700 starter with compressed air; 15 HP (11 kW) or compressed air from two air cylinders. The capacity of six main fuel tanks was 400 liters, four spare - 360 liters. The range of the car on the highway reached 310 km.

The transmission included a multi-plate dry friction main clutch; five-speed gearbox; two multi-plate side clutches and two final drives. Side clutches were used as a turning mechanism. Control drives - mechanical.
In connection with the front location of the cabin, reinforced front rollers were mounted on three ball bearings. At the same time, the front suspension units were strengthened. In the course of serial production, a device was introduced for tensioning the caterpillar with a guide wheel, as well as a device for self-pulling the machine when it got stuck.

The electrical equipment of the machine was made according to a single-wire circuit (emergency lighting - two-wire). The voltage of the on-board network was 24 and 12 V. Four 6STE-128 rechargeable batteries connected in series-parallel with a total capacity of 256 Amph and a GT-4563-A generator with a power of 1 kW and a voltage of 24 V with a relay-regulator RPA- 24F. Consumers of electrical energy included a ST-700 starter with a starting relay for starting the engine, two MB-12 fan motors that provided ventilation for the fighting compartment, outdoor and indoor lighting devices, a VG-4 signal for external sound alarms, an electric trigger for the gun firing mechanism, a heater for the protective glass of the sight, an electric fuse for smoke bombs, a radio station and an internal intercom, telephone communication devices between crew members.

For external radio communications, a 9RM or 9RS radio station was installed on the machine, for internal communications - a TPU-Z-BIS-F tank intercom.
The large barrel reach (3.53 m) made it difficult for the SU-100 to overcome anti-tank obstacles and maneuver in limited passages.

Hey tankers!!! Let's talk about the Soviet tier 6 tank destroyer: the SU-100.

Development history

The SU-100 was created on the basis of the medium tank T-34-85 by the design bureau of Uralmashzavod in late 1943 - early 1944 as a further development of the SU-85, due to the latter's insufficient capabilities in the fight against German heavy tanks. Serial production of the SU-100 was launched at the Uralmash plant in August 1944 and continued until early 1948. In addition, in 1951-1956, its production under a Soviet license was carried out in Czechoslovakia. In total, 4976 self-propelled guns of this type were produced in the USSR and Czechoslovakia. The first combat use of the SU-100 took place in January 1945, and later the SU-100 was used in a number of operations of the Great Patriotic War and the Soviet-Japanese War, but in general their combat use was limited. After the war, the SU-100 was repeatedly modernized and remained in service with the Soviet army for several decades. SU-100s were also supplied to the allies of the USSR and participated in a number of post-war local conflicts, including the most active during the Arab-Israeli wars. By the end of the 20th century, the SU-100 was decommissioned in most of the countries that used it, but, nevertheless, in some of them, as of 2007, it still remains in service. The main weapon of the SU-100 was a 100-mm rifled gun. D-10S arr. 1944 (index "C" - self-propelled version), which had a barrel length of 56 calibers / 5608 mm. The gun provided the armor-piercing projectile with an initial velocity of 897 m/s. The cannon was installed in the front plate of the cabin in a cast frame on double trunnions, which allowed it to be aimed in the vertical plane in the range from -3 to +20° and in the horizontal ±8° (in the game we have ±12°). The technical rate of fire of the gun was 4-6 rounds per minute. During the Great Patriotic War, the armor penetration of the D-10S allowed it to hit the frontal armor of most German tanks and self-propelled guns. The D-10S proved to be capable of penetrating the frontal armor of the Tiger and Panther, including the latter's upper frontal plate, which penetrated at a distance of 1,500 meters, exceeding the calculated capabilities of the gun. The side armor of German tanks, even on the heaviest production models, was vertical or located with insignificant angles of inclination and did not exceed 82 mm, like the frontal armor of the main massive medium tanks and self-propelled guns - Pz.Kpfw.IV and StuG.III / IV, made their way from a distance 2000 meters or more, that is, at almost all real combat distances. A certain problem for the 100-mm gun was only the frontal armor of the Tiger II tank and the Ferdinand and Jagdtigr self-propelled guns produced in small series. At the same time, as shown by shelling tests of the armored hull of the captured "Tiger II", carried out in Kubinka, hitting the frontal armor with 3-4 armor-piercing or high-explosive fragmentation 100-mm shells from a distance of 500-1000 meters led to the formation of cracks, chips and destruction of welds, which ultimately led to the failure of the tank. Uralmash engineers L. I. Gorlitsky, A. L. Kizima, S. I. Samoilov; engineers of plant No. 9 A. N. Bulanov, V. N. Sidorenko and mechanical engineer P. F. Samoilov for the creation of self-propelled guns in 1946 were awarded the title of laureate of the Stalin Prize of the first degree.

Any gun is installed on the stock chassis. If you, while riding the SU-85, explored the 85 mm D-5S-85BM gun, then we ride with it, if not, then we suffer with the stock gun and save up 16,500 stars for the historic 100 mm D-10S gun (this gun is a worthy representative SU-100, but I will write about this below). Next, we research the 122 mm D2-5S gun for 17,000 experience. Well, at the end, the top engine, top suspension, and 85 mm D-5S-85BM (if not investigated). We get the top radio from the SU-85. I advise you to immediately research the SU-152 and SU-100M1 (even if your goal is any one branch of the Soviet tank destroyers, an open tank of the 7th level will never hurt).

(guns from top to bottom: 85 mm D-5S, 85 mm D-5S-85BM, 100 mm D-10S, 122 mm D2-5S)

Crew and perks

Commander, gunner, driver, loader.
The first perk to the commander is a light bulb, the rest are repairs. Repairs for the second commander, disguise for the rest, and then we drop it and take the combat brotherhood for everyone. The third is downloading what was originally the second. The fourth perk is for the radio interception commander, the sniper gunner, the virtuoso mech-water, which charges the non-contact BC.

Modules

Naturally, we put the horns, rammer and drives / ventilation to choose from.

tank in game

The SU-100, like its predecessor the SU-85, is a classic example of a tank destroyer. There are no features that allow this machine to do "unusual" things in combat. And how to play this technique, I think, any tanker who has from 1k battles knows. We find a bush and work on someone else's light. Naturally, you need to know all the bushes where you can inflict damage and the principles of disguise, which will allow you not to receive unnecessary damage (all this comes with the growth of combat experience). The safety margin of the SU-100 is 580 units, so remember the rule of "three splashes". Contrary to the armor, the upper frontal part is 75 mm. and a slope of 50 degrees, the level tanks pierce us without problems. If you put the body in a rhombus, thereby increasing the reduced armor, you can avoid damage. NLD has 45 mm. and a slope of 55 degrees, i.e. I'll get us there for sure. The strongest place in the forehead is the junction of armor plates (120 mm) and the gun mantlet (75 mm). Well, the well-known hatch in the VLD, where 65 mm., And where everyone who gets through breaks through us.

The entire back of the tank is the engine and tanks, if they fire at the sides or stern, then there is a high probability of a crit or fire. Also often "pleased" ammo rack, located in front of the tank.
But in this section, I would like to pay more attention to the topic of gun selection for the SU-100. Which is better: 100 mm. historical gun or 122 mm.? I warn ardent fans of this birdie: all of the following is purely IMHO. Let's start.

As a result, we get that 122 mm. the gun won only in one indicator: average damage. But without a doubt, this is enough to surpass all the advantages of 100 mm. tools. Imagine a situation: you are standing in the bushes, and a KV-1S with 350 HP is driving at you, he does not see you. If you shoot with a 122 mm gun, then the KV-1Ca will probably shoot. With a 100 mm gun. You'll need a second shot to finish off the KV-1Ca, but the KV-1C will spotlight you and finish you off by then. But it is worth remembering that the enemy’s rep is not next to you, but on the other side of the map, and while he is coming towards you, you will work on him from long and medium distances, standing in the bushes and staying out of light. With the role of a sniper 100 mm. the tool works better. Penetration of 175 units. both guns have enough bbs for level 6 and 7, but if you get thrown into level 8, then it is very difficult to penetrate the same Lowe in the NLD with a penetration of 217 mm., provided that it stands in a rhombus. But 235 is enough to punish the entire 8th lvl. After interviewing 20 of my friends who rode the SU-100, I found out: 16 of them drove all the battles with 122 mm. gun and not about any 100 mm. the guns did not even want to hear. But the other 4 friends claimed: “Everyone who rides with 122 mm. tool - noobs. Personally, having skated a couple of battles with the top gun, I noticed that my average damage on the tank had dropped sharply, and the rest of the battles went through with 100 mm. cannon. And, of course, the conclusion: 122 mm. and 100 mm. guns are equally good. Yes, in some specific game situation 122 mm. the tool will perform better, and in the other - vice versa. But in general, the choice of weapons should depend on the style of play. To do this, you need to play with that weapon, and with another, and then just compare the results. Where the results are better, there is your tool . And finally, according to tradition, I suggest you familiarize yourself with this WOD:
