The Iosif Stalin tank (or IS tank, also known as the Joseph Stalin tank), was a heavy tank developed by the Soviet Union during World War II and first used in the Kursk area in September 1943. The tanks in the series are also sometimes called JS or ИС tanks.
The heavy tank was designed with thick armour to counter the German 88 mm guns, and carried a main gun that was capable of defeating the German Tiger and Panther tanks. It was mainly a breakthrough tank, firing a heavy high-explosive shell that was useful against entrenchments and bunkers. The IS-2 was put into service in April 1944, and was used as a spearhead in the Battle of Berlin by the Red Army in the final stage of the war.
