12th Rifle Corps

The 12th Rifle Corps (Russian: 12-й стрелковый корпус) was an infantry corps of the Red Army during the interwar period and World War II, formed four times.

The corps headquarters was briefly active between late 1922 and early 1923 as part of the Separate Caucasus Army, and again between early 1923 and early 1924 in Western Siberia. Reformed in 1930 and stationed in the Volga Military District, the corps headquarters moved to the Transbaikal in 1939. There, it was used to form the 36th Army in July 1941.

The corps was again reformed in late 1942 as part of the Transcaucasian Front, spending the war guarding the Soviet–Turkish border. From 1946 it was stationed in the North Caucasus Military District, and briefly became a mountain rifle corps between 1949 and 1954. The last formation of the 12th Rifle Corps became the 12th Army Corps in 1957, and was expanded into the 49th Army in 1992.
