The ISU-122S was a Soviet World War II heavy tank destroyer and assault gun, built on the IS chassis and armed with the powerful 122 mm D-25S cannon. Featuring a shorter barrel and faster rate of fire than the standard ISU-122, the ISU-122S was designed for both anti-tank combat and direct fire support.
