Карельский перешеек
Formed in May 1941 in Karelia, it fought in the Continuation War against Finland in the Karelian Isthmus, defending the northwestern approaches to Leningrad during World War II. After Finland withdrew from World War II in September 1944, the army remained on the Finnish border. It continued to garrison the Karelian Isthmus postwar and was disbanded in 1948.
