 For example, the ranks included "Lieutenant" and "Comdiv" (Комдив, Division Commander).Further complications ensued from the functional and categorical ranks for political officers (e.g., "brigade commissar", "army commissar 2nd rank"), for technical corps (e.g., "engineer 3rd rank," "division engineer"), and for administrative, medical and other non-combatant branches.The Marshal of the Soviet Union (Маршал Советского Союза) rank was introduced on 22 September 1935.
