The T-34/85, the very symbol of Soviet military strength in the Second World War, had a new turret to house the more powerful 85mm ZiS gun. A supremely rugged and reliable tank, the T-34/85 had excellent off-road capability, especially in the marshland or snow of the Eastern Front, and was easy for the crew to operate and maintain.
The T-34/85's great strength lay in its adaptation of the T-34/76 tank design which preceded it. This ensured a far smoother and faster production line than would have been the case with a completely new design. Another major advantage of the relatively simple design is the sheer number of tanks the Soviet tank factories could produce - by the summer of 1944 the Soviet war machine could produce more T-34/85s in a month than the Germans had Panther tanks in the whole of the Eastern Front!
