The T-34 was a Russian tank of the Second World War, which was first produced in 1941. The first models weighed 26.7 tonnes, carried a five-man crew and were protected by sloping armour up to 60 mm thick, armed with a 76. 2 mm gun capable of firing both AP and HE rounds. Early models had a 500 bhp engine which gave a top speed of 31 mph and a range of 450 km. In 1943 the T- 34/85 model was introduced with an 85 mm gun and the armour increased to 90 mm. Research T-34
