ザバイカル軍管区
Formed in mid-1941, the army spent much of World War II as part of the Transbaikal Military District guarding the Manchurian and Mongolian-Soviet borders. During the Soviet invasion of Manchuria in August 1945, the army advanced over the Greater Khingan mountains and overran the Japanese Hailar fortified region in fierce fighting. It was disbanded after the end of the war in mid-1948.
