The Soviet T-34 was the most produced tank of the Second World War and its revolutionary sloping armour became a major influence on future tank design. With its combination of heavy firepower, mobility and protection, the T-34 gave the Red Army a war-winning weapon with which to break the German Army on the Eastern Front. A mainstay of the Soviet armoured divisions, it was widely exported after the war and in 2017 it remains in frontline service with many third world countries. Author Mark Healy combines a detailed technical examination of the T-34 with its legendary combat history.
