GarageImage T-34E STZ.jpg

The T-34E STZ is a rank II Soviet medium tank with a battle rating of 4.0 (AB/RB) and 3.7 (SB). It was introduced in Update 1.49 (1.70.1945) "Weapons of Victory". An up-armoured version of the T-34 (1941) tank, the T-34E STZ utilizes much improved frontal hull armour in comparison to the standard T-34 tank.

This tank has great front protection and while not invulnerable, many enemy tanks will have difficulty knocking it out. The rest of the armour of the tank is decent, but nothing that is too difficult to penetrate. While the extra armour of the T-34E STZ greatly increases frontal protection and it does slow the tank down. This combined with a great gun and a large selection of ammunition types makes this tank a jack of all trades.

Main armament

Main article: F-34 (76 mm)

The T-34E STZ has the same gun and ammunition selection as the preceding T-34 (1942). The BR-350B APHEBC shell should be the main round of choice due to its good penetration and explosive filler. The others are more situational but can still be nice to have.

  • BR-350SP APBC has better penetration and can be useful when facing slightly more resilient targets like welded hull Shermans and uparmored Panzer IVs, which are less consistently penetrated by the BR-350B shell at medium ranges, though its lack of explosive filler means that follow up shots may be required.
  • BR-350P APCR shell is helpful for attacking heavily armored targets but has poor post-penetration damage and is nearly useless against sloped or angled armor.
  • OF-350M HE shell can be used to hull-break light targets such as SPAAs and armored cars.
  • Sh-354T shrapnel shell has limited utility; it may be useful against thinly-armored targets resistant to hull-break, but most of the time the APHEBC shells are effective enough in these situations.
  • BP-350A HEAT shell has poor ballistics and mediocre penetration, but actually has more explosive filler than the HE shell — better for hull-breaking if you can make your shots connect.

Lastly the D-350A smoke shell is available. Since the T-34 series lacks smoke grenade launchers, it is good to carry a few of these for covering advances and blinding entrenched enemies.

Usage in the battles

There are two main ways to utilize this tank. The first is by staying at long range, and using the frontal armour and good gun to pick off enemies. When at long range remember that the front turret is the greatest weakness of this tank so try to not look directly at the enemy during reloading. The second is as a close-range brawler when using the tank in this manner make sure to watch the flanks. Both of these methods are equally viable, at close range seems to be where this tank does a little better.

The first option is to go straight for a cap point and find a good position just outside or just inside the point. Any position that has a good overwatch of the cap point or the approaches to the cap point will do. Once in position try to knock out any tank that tries to approach the point, make sure to properly angle the armour to maximize protection. If aware of where the enemy is coming from, it is easy to maximize the armour protection and engage enemies with an advantage. Always engage in the most favourable conditions, these means don't hesitate to retreat if starting to get overwhelmed. If the enemy follows through while retreating, they could expose themselves to allies to take them out.

The second option is to try to flank around them and approach the enemy from an angle they might not expect. When doing this try to make sure to have a good knowledge of the terrain, since choosing the wrong path means a bad encounter and demise. A good path is one where enemies appear in a predictable location and allow for disengagements with easy withdrawal. Ideal paths have a hill between the T-34E and the enemy, allowing the T-34E to manoeuvre slowly around the hill until the enemy is in sight. Once the enemy is sighted, engage if applicable. If the enemy starts charging, fight a fighting retreat using the hill as cover. However remember if moving around the flanks, it will be harder to receive team support if away from the main body of allies.

  • Urban

Urban settings can be challenging for the T-34E STZ. The reason for this is while the frontal armour is great, in the chaos of urban combat means that no one may know where the enemy is at. Another problem; while the front armour is good it does have a number of weak spots which can be easily targeted at point blank range. With that in mind, play the STZ as in a 1941 or 1942, and do not rely on the armour as with a KV-1. Try to use the flanks and side streets to get into firing position where enemies can come from a predictable path. This will allow maximum usage of the T-34E's mobility and protection to the fullest. The T-34E's agility is its main defence in these settings.

  • Open Field

In this type of environment, tank destroyers will always reign supreme. Their combinations of high-power guns, low profile, and tough frontal armour make them great long range combatants. However, the T-34E's armour allows the tank to play along, but always remember that it is not invulnerable, and while the F-34 gun cannot match those of tank destroyers', it can still get the job done. This means that the T-34E should not position itself in the open and take shots, try to find a location where the tank is protected from most angles and focus on one enemy at a time. By focusing on one tank at a time, it will minimize the odds of a lucky shot hitting weak spots.

  • Hill Country

This is the type of environment where T-34 STZ can really shine. The reason for this is that unlike in urban environments flaking can be a little more difficult. The average distance of engagement is longer, meaning the enhanced armour can do more than in urban environments. The more open nature allows the T-34E to make full use of the tank's mobility. When in this environment, there is a range of options and tactics to take on the enemy.

Some enemies to be concerned about:

  • M4A3E2 Jumbo - The frontal armour on the Jumbo is difficult to penetrate even with APCR shells, the only weak point being the machine gun port. If encountered, get out of its line of sight and try to flank it if possible. A good location to target is the lower hull side, behind the tracks. This section has not been uparmored and a good shot below the crew compartment can detonate the ammo racks and send the Jumbo back to the hangar.
  • Pz. IV F2 - Despite its thin armour, the Pz. IV F2 has a gun fully capable of penetrating the T-34E's armour easily. If encountered, move to a safe position where it is still observable. Wait until it is not targeting directly at the T-34E, then shoot it in the main hull. Often one shot is all it takes. Alternatively, if feeling lucky, try to get the first shot off into the front of the tank. It should, if not an instant knock-out, at least disable a few crucial crew members and/or modules.
  • M10 - This tank destroyer will comfortably destroy the T-34E with the 3-inch gun if it gets a chance to. Treat it like the Pz. IV F2, fragile but powerful. Make sure it isn't looking towards the T-34E's way, then shoot it in the main hull and it will, at the very least, fatally incapacitate it.
  • M18 GMC - Fight similarly to the M10 or Pz. IV F2. Be wary of close quarters engagements due to their outstanding mobility. Vulnerable to hull break, consider using HE or HEAT rounds.
  • Achilles - An M10 with a more powerful gun. Treat like the M10, except more carefully. However, the poor turret traverse and long reload mean that if it's facing in a different direction or if it just fired, there is the possible risk of exposing the T-34E STZ and taking a shot into the main hull.
  • Sherman Firefly - A Sherman with a more powerful gun. Its frontal armour, like all Shermans, is difficult for the F-34 gun to penetrate. Its gun is also more powerful than the traditional Sherman, making it even more problematic to deal with. If possible, engage from the side and fire into it. Otherwise, treat like the Jumbo and avoid entirely.
  • M4A3(105) - Treat like a Sherman Firefly, an up-gunned Sherman. Avoid getting hit, as its 105 mm shells can cause major damage and perhaps send the player back to the garage. Try hitting the side or the gun mantlet to OHK or disable the gun respectively.

Pros and cons


  • A smaller turret than the previous T-34 (More difficult to hit flat parts)
  • Turret cheeks have a relatively flat and angled edge compared to the pronounced curve of the 1940/1941 T-34 variants, slightly harder to penetrate
  • Better front armour (60mm) than the previous T-34
  • Good gun
  • Lots of ammunition variety
  • Good mobility


  • The added armour does not cover all the front armour, machine gun port is still a large weak spot in close quarters engagements
  • Turret armour, especially the cheeks, are still big weak points
  • Weak side armour
  • Slower reload than the 1942 variant
  • Bad gun depression


The T-34 was beginning to become the main tank of the Soviet Army by 1941, however, the initiation of Operation Barbarossa by the Germans postponed most manufacturing deadlines due to the relocation of various factories to the Ural Mountains to keep them safe from the Germans. During the movement, only the Dzherzhinski Tractor Factory in Stalingrad (STZ) stayed in production and produced most of the T-34s during the relocation.

To increase the survivability of the tanks, the T-34 design in the STZ factory was up-armoured by use of applique armour plates. These applique armour variants of the T-34 were called T-34E, with "E" meaning ekranami translates to "with screens" in Russian. These tanks were given applique armour throughout the entire vehicle, on all sides of the turret, one the front, on the sides, and even side skirts on the tracks. Some of the applique armour was placed in a way to act as spaced armour against enemy fire, which proved quite effective against the Panzer III's 50 mm KwK 39 cannon where the armour applied were on areas once vulnerable on the T-34 to the cannon. However, it was found that this additional armour did not help the T-34 against larger calibres such as the 75 mm PaK 40 and the 88 mm FlaK cannons. Due to the gradually growing number of tanks with the 75 mm and 88 mm, such as the up-gunned Panzer IV and the Tiger I that could easily destroy the T-34 even with the armour application, the armour configuration was not placed into mass production and thus only the testing batch of 47 units were made from the design.

However, one armour applique model produced in STZ did see more widespread use in the production line, though it still had the name T-34E as its main nomenclature (called the T-34E STZ in-game). This up-armoured model was more successful than the previous due to not drastically changing the design and only focusing on front armour protection by welding 15 mm of armour onto the front hull, thus minimizing weight gain by only focusing on the area most expected to be hit. The tank also featured redesigned road wheels and track designs. These T-34Es saw more widespread use and have photographs showing it being used in the Leningrad Front.

In-game description

A version of the T-34 medium tank with enhanced combat capabilities, especially in terms of armor. Additional armor plates were added to the body and turret. This was made necessary by the appearance and widespread use by the Wehrmacht of new, more powerful anti-tank weaponry.
