The T-34 was one of the most classic medium tanks during WWII. After the war, it continued its military service in many countries. It was a great shock to enemies when it appeared on the battlefields. This tank had a profound effect on the design and operation of generations of Russian tanks after WWII. For example, the engine used on T-72 main battle tanks was a variant of the B-2 engine used on the T-34 medium tank.
