Popularly called 'Victory Tanks', the losef Stalin tanks were the ultimate heavy tanks create by the Soviet Union. They played a crucial role during the Second World War, named the victory tanks due to their close association with the defeat of Germany in 1945. However, they had a troubled start to production.
