T-34 medium tank Hoodie

The T-34, a Soviet medium tank, had a profound and lasting effect on the field of tank design. At its introduction in 1940, the T-34 possessed an unprecedented combination of firepower, mobility, protection and ruggedness. Its 76.2 mm (3 in) high-velocity tank gun provided a substantial increase in firepower over any of its contemporaries while its well-sloped armor was difficult to penetrate by most contemporary anti-tank weapons.
