What is "komkor"

Komkor is the abbreviation to Commanding officer of the Corps ( / Командир корпуса; literal: Commander of the corps / Corps commander), and was a military rank in the Soviet Armed Forces of the USSR in the period from 1935 to 1940. It was also the designation to military personnel appointed to command a corps sized formation (XXX).

Until 1940 it was the fourth highest military rank of the Red Army, and might have been rated OF-8 in NATO ( Three-star rank). It was equivalent to Corps commissar (ru: Корпусной комиссар) of the political staff in all military branches, '' Flag Officer 1st rank'' (ru: Флагман 1 ранга) in the Soviet navy, or to Commissar of state security 3rd rank (ru: Комиссар государственной безопасности 3-ого ранга). With the reintroduction of regular genera ranks, the designation Komkor was abolished, and replaced by Colonel general (OF-8).
