The T-34E STZ is an armoured modification of the T-34 (1941), which is the second variant of the T-34 medium tank family. When the Germans were confronted with the significantly better-protected T-34 medium tanks during Operation Barbarossa, they promptly began improving their current designs to combat it. In response, many early T-34 variations, such as the T-34E STZ ("ehkranami" - screened), had additional armour plates welded to the front in an attempt to improve the tank's protection. The frontal hull protection was significantly increased over the original T-34 (1941) variant. This modification was principally performed in the STZ factory in Stalingrad in January 1942.

Introduced in Update 1.49 "Weapons of Victory", the T-34E STZ is essentially an armoured derivative of the T-34 (1941) variant. It is not a distinct variant in and of itself since nothing was modified from the T-34 (1941) variant, except the addition of a thin armour plate to the frontal hull. The gameplay is nearly identical to those of the other early T-34 variants (1941 and 1942). With the same long-barrelled 76.2 mm F-34 tank gun and an extensive selection of ammunition, players will be glad to discover that the T-34E STZ is significantly better protected against adversaries from the front. While the T-34E STZ's increased armour substantially improves frontal protection, it does slow the tank down.
