The 25th Army was a Red Army field army of World War II that served in the Russian Far East. Formed in June 1941, the 25th Army did not see combat until the Soviet invasion of Manchuria in August 1945, when it advanced into northern Korea. After World War II it was responsible for the Soviet Civil Administration in the northern Korean Peninsula, and helped establish a Communist state in North Korea under the rule of Kim Il-Sung. The army remained in North Korea until it was withdrawn in 1948, and was stationed in Primorsky Krai until its 1957 disbandment.
