The SVT-40 is a Soviet semi-automatic battle rifle. The SVT-40 saw widespread service during and after World War II. It was intended to be the Soviet Red Army's new service rifle, but its production was disrupted by the German invasion in 1941, resulting in a change back to the Mosin–Nagant rifle for the duration of World War II. After the war, the Soviet Union adopted new rifles, such as the SKS and the AK-47.
