Tank Corps (Soviet)

A tank corps is a big group of tanks that the Soviet Union (now known as Russia) used in World War 2. It was made up of many different kinds of tanks, including big ones that were used to break through enemy lines and smaller, faster ones that could move around to attack the enemy. All of the tanks in the corps were very strong, and the soldiers who drove them were very brave. The tank corps helped the Soviets to win many important battles during the war.
