The Kar98k is a bolt-action rifle chambered for the 7.92×57mm Mauser cartridge. It was adopted on 21 June 1935 as the standard service rifle by the German Wehrmacht. Although supplemented by semi-automatic and fully automatic rifles during World War II, the Karabiner 98k remained the primary German service rifle until the end of the war in 1945.[4] Millions were captured by the Soviets at the conclusion of World War II and were widely distributed as military aid. The Karabiner 98k therefore continues to appear in conflicts across the world as they are taken out of storage during times of strife.
