Colonel general
Until 1940 it was the fourth highest military rank of the Red Army, and might have been rated OF-8 in NATO . It was equivalent to Corps commissar of the political staff in all military branches, Flag Officer 1st rank in the "Soviet navy", or to Commissar of state security 3rd rank . With the reintroduction of regular general ranks in 1940, the designation "Komkor" was abolished, and replaced by Colonel general (OF-8).
