Description

The SU-76M (5th Guards Cavalry Corps) is a premium gift rank II Soviet tank destroyer with a battle rating of 2.0 (AB/RB/SB). It was introduced during Update 1.49 "Weapons of Victory". The vehicle was made available during the WW2 Chronicles and "Tanker's Day Specials!" events in 2015, and again in the Victory Day Tournament and "Happy tanker's day!" events in 2017.

The finest example of a so-called "glass cannon", SU-76M is a small, nimble SPG, but its strongest trait is its gun – the 76.2 mm (3-inch) ZiS-3 possesses a good rate of fire, is able to frontally penetrate and destroy any opposition at the given BR spread, and its shrapnel round is extremely effective against self-propelled anti-aircraft guns and other lightly armoured vehicles, making the HE shell somewhat redundant.

The SU-76M shares a similar hull armour profile with the T-70 light tank on which it is based. The hull, with a large, well-angled 25 mm upper front plate, might bounce some shells when the hull is angled, but high-penetrating guns such as 5 cm Kwk 39 can still penetrate it easily. Once penetrated the driver will get knocked out, or the transmission/engine will be broken, immoblising the tank. On the back of the hull, the SU-76M has a lightly armoured open-topped superstructure to accommodate the 76 mm gun. With a maximum thickness of only 25 mm and poor angling, the superstructure will not stop much more than heavy machine gun fire. Common tanks such as Pz.II, M3A3, AB 41, etc are all able to penetrate the front of the fighting compartment with ease, and knock out any crew in the shell path. The crews are quite cramped together too, further decreasing the survivability against explosive-filled rounds. It is only able to resist rifle-caliber rounds or heavy machine gun fire from far away.

The open top also makes the SU-76M very vulnerable to aircraft strafing runs from above or behind.

Main article: ZIS-3 (76 mm)
The SU-76M is armed with the 76 mm ZiS-3 field gun, a versatile artillery piece that is very capable of performing in the anti-tank role at this BR. It has a decent rate-of-fire and a wide traverse arc, but the mounting has very poor gun depression due to the obstruction of the hydraulic recoil cylinder below the gun barrel.

It has a very wide selection of ammunition, though only a few are worth using regularly. The stock BR-350A APHEBC shell is adequate enough for most purposes, although it will struggle against heavy tanks like the Churchill at long ranges. The BR-350B APHEBC shell is arguably the best all-round projectile available, combining decent penetration with excellent lethality, allowing it to frontally penetrate almost all tanks it will face. Against particularly heavy armour, the BR-350P APCR shot is available, though its poor lethality and performance against sloped armour will tend to disappoint, for example against a M4A3(105). The BR-350SP APBC shot is a solid shot round with no filler, but it creates more spalling than the APCR and is somewhat more lethal. The BP-350A HEAT round is occasionally useful for long-range fighting since it does not lose penetration with distance, but the Soviet 76 mm guns generally do not perform very well at long range, and work better at medium to close range. The Sh-354T shrapnel round creates a lot of fragments when it penetrates, but is only effective against lighter vehicles.

Due to the rather curved shell trajectory, the SU-76 is best used at close to medium ranges (0-800m) where the trajectory does not impact the accuracy too much. Beyond 800m, it is still viable, though considerably harder for new players to aim.

Usage in battles

As is common with Tank Destroyers, the SU-76M needs to be handled with care. Not only does it not have a rotating turret, it has an open top and practically no protection from behind. Therefore, when an engagement's complexity evolves and the Su-76 is surrounded, there is little that can be done to survive. One well placed hit to its rear will knock out a good part of the exposed crew, even machine guns can do the job of eliminating both loader and gunner.

Therefore, it is crucial to remain at a distance from the enemy, perhaps even seek the cover of trees for protection against low-level attack aircraft, and to only ever give the front side to an enemy. The fact that this vehicle does not have a turret not only means that it is not effective when fighting more mobile enemies attempting to flank, it also means that placing the armour at an angle is not a viable strategy to increase relative armour thickness and stay more protected, since the gun's limits for horizontal traverse mean that any significant angle of the hull towards an enemy will make make it harder to keep the enemy in sight. What can be done is to fire a shot and, immediately after, angle the hull whilst reloading, to then return to facing the enemy to fire another shot. However, hiding whilst reloading is the most sensible choice.

Unfortunately, the SU-76 has fairly poor mobility, handling, and a vastly different gun when compared to its smaller and more mobile cousin, the ZiS-30. However, the gun on the SU-76 is definitely more powerful than the ZiS-30's 57 mm. The sheer force of the 76 mm shells will cause huge amounts of trauma to a target upon penetration. The SU-76 is also more well armoured than the ZiS-30 and provides much more protection to the gunner crew, especially from smaller caliber rounds (Unless fired from the rear). Given its poor gun depression and velocity, the SU-76 should be used as a mobile brawler and ambusher. It is well suited to performing ambushes in urban areas. The high HE filler of the 76mm shell makes it capable of OHK'ing nearly all enemy armour at its 2.3 BR. A minor issue with the SU-76 is that it has no defensive machine gun, meaning that responding quickly to SPAA is difficult.

The gun in itself is what makes the SU-76M a good vehicle, all its other characteristics are less than impressive. The variety of ammunition is a definite pro for this SPG, its APCR and HEAT shells being effective even at higher ranks, giving this humble tank destroyer the ability to down higher-ranking tanks like the Tiger H1. Recently, the much more effective late-war BR-350B ammunition has been added to the SU-76M's ammunition options. It features noticeably more penetration and a better fuze in exchange for somewhat less explosive mass. Despite this, the SU-76M will often destroy most enemies in one shot when the shells penetrate. Once unlocked, the SU-76 is quite capable of dealing with any tank it is likely to see from the front, though there may be a need to swap ammunition often to deal with different targets.

Enemies worth noting:

M4A3 (105): This low-rank Sherman posts a huge threat to every of its opponents due to its superior armor and destructive firepower. Its armor is overall quite tough to penetrate with your short 76mm gun, but it can be solved by careful aiming. If the M4 is within 200m, use default APHE to shoot at the vertical part of its gun mantlet or its side if exposed. If it's hull down within 100m, only target the gun mantlet with either APHE or APCR to disarm it. When the M4 is further than 400m away, all of your shells will perform poorly at penetrating its armor, so disengage or wait until it gets closer. Remember to not get hit by it, its HE or HEAT is likely to knock the SU-76 out with ease.

Pros and cons

Pros:

  • Decent horizontal gun traverse of 30 degrees-no need to constantly adjust hull position
  • Great cannon, its deadly APHEBC packs a heavy blow for common opponents like the Pz.IIIs, Crusaders and Stuarts
  • Offers a wide range of ammo to deal with various opponents: APHEBC for normal targets, HE / shrapnel for soft targets and APCR for the hard ones
  • Small profile makes it easy to hide and set up ambushes
  • Adequate acceleration and hull traverse
  • Carries up to 60 rounds of ammo which is plenty even for a long battle

Cons:

  • Open topped, very vulnerable to strafing aircraft
  • Thin armour struggles to protect the crew from even .50 cal
  • -3 degrees of gun depression isn't enough for hill combat, and this flaw is sometimes fatal
  • No MG, so killing vehicles with light armor / exposed crew is rather ineffective, for example SPAAs
  • Poor reverse speed of only 5 km/h might get the player killed
  • Cannon penetrates poorly at more than 700m. Will struggle to pen hard targets like the Matildas, early Churchills and Sherman

History

Development

During the interwar years, the development of self-propelled artillery was practically nonexistent in the Soviet Union. Those few projects, based on the chassis of T-26 light tank, such as SU-1, AT-1 or SU-26, were eventually cancelled, and the Red Army entered the Second World War entirely without a dedicated self-propelled gun.

The situation changed after the German invasion in 1941, and vehicles such as the SU-152 or SU-122, based on the KV-1 and T-34 tanks respectively, were developed. In November 1942, the State Defense Committee then ordered the production of a light self-propelled gun, built on the chassis of a light tank and armed with a 76.2 mm gun. The T-70 light tank chassis was chosen, as the other light tanks, the T-50 and T-60, was already out of production. The chassis had to be modified for this role, so it was lengthened and had one additional pair of road wheels added to the design. The armament, the 76.2 mm divisional M1942 gun (also designated ZiS-3), was mounted in a fully enclosed case mate. The gun was positioned at the rear, with the transmission being mounted frontally.

The vehicle was designated SU-76 (Samokhodnaya Ustanovka, "Self-Propelled Gun"), and the production was issued to the No.38 Factory in Kirov and started in December 1942. However, after only a couple of hundred vehicles were produced, the production was halted due to serious mechanical problems and other issues. The power train consisted of two GAZ-202 automobile engines, with each powering one track. However, there was no synchronization gear, so the driver has to control both engines simultaneously, which was an extremely difficult task. This arrangement also caused strong vibrations, which were the cause of frequent engine and transmission failures. The second biggest issue was the enclosed crew compartment, as it was very cramped and offered only a little space for crew members to work properly. The vehicle thus had to be modified, firstly the roof of the crew compartment was removed, improving the access to the gun. The power train was also changed, receiving the more powerful GAZ-203 engines, each producing 85 horsepower, which were now mounted in tandem on the right side of the vehicle, propelling a single drive-shaft. The modified vehicle was designated SU-76M, and its production was resumed in early 1943. More than 14,000 SU-76M's were produced between 1942-1945, making it the second most produced armoured vehicle in Soviet Union after the T-34 tank.

Combat usage

In its intended role, the SU-76M replaced earlier infantry support tanks and was very welcome to Soviet infantry units as it provided them with a light and mobile universal support weapon. The vehicle was meant to be part of three battlefield roles - a light assault gun, a mobile tank destroyer, or a mobile artillery gun as the weapon could be fired indirectly at a range of 17 km. The vehicle was fairly lightweight and produced low ground pressure, enabling it to pass through terrain unsuitable for heavier vehicles. Tts gun could utilize multitude of ammunition types, aside from standard high explosive ammunition, it could use fragmentation, shrapnel, incendiary and smoke rounds. As a tank destroyer, the gun was sufficient against German light and medium tanks such as Panzer III or Panzer IV. The introduction of the APCR and HEAT rounds then enabled SU-76M units to engage even heavier Panther and Tiger tanks with some success, though crew manuals instructed the gunner to try to hit the tracks or gun barrels before these rounds were made.

The vehicle also proved itself effective in an urban environment, where it was used as an assault gun for direct fire against enemy strong points and fortifications. The open-topped casemate made the crew vulnerable to snipers and hand grenades, but it also made the communication between vehicle commander and any accompanying infantry easier. Plus, it was found that the open compartment actually helps against the German infantry anti-tank weapon Panzerfaust, where a closed space would ensure the death of the crew members from the blast concussion amplified in the closed space. The SU-76M's low ground pressure from its weight made it one of the only Soviet vehicles able to operate in swampy terrain, which was extremely helpful during the Belarus Campaign in 1944, allowing the vehicle to attack through swamps in raids. This allowed the Soviets to bypass German defensive areas on more suitable terrain with support of an assault gun accompanying the light infantry. This vehicle was commanded by the units of the 5th Guards Cavalry Corp, equipping it with the necessary camouflage paint and insignias consistent with their unit. The 5th Guards were created in November 20, 1942 and consisted of the 11th and 12th Guards 'Don' Cossack Cavalry Division and the 63rd Cavalry Division. These were ordered to support the Transcaucasus Front and so participated in the Iassy-Kishinev Offensive, Battle of Debrecen, Budapest Offensive, and the Vienna Offensive.

After the end of World War II, the SU-76M was phased out of production, but many of them were exported to other countries, such as China, Cuba, North Korea, North Vietnam or Czechoslovakia, where they would be used in conflicts such as the Korean and Vietnam War against the US and their allies.

Survivors

Due to the large quantity produced and usage after World War II, many are found in intact conditions today in various locations around the world. Some could even be found as war monuments for the Soviet and German memorials.
