level, reserved for most honored field commanders Eventually, the Soviet system of general ranks included commonplace Major General, Lieutenant General, however, the position between Lieutenant General and General of the Army was occupied by the Colonel General, which in the Soviet system is the equivalent of a full General rank in other nations. This unusual rank structure makes rank comparisons difficult; Marshal of the Soviet Union is arguably not the equivalent to NATO five-star general ranks such as British Field Marshal or American General of the Army, but is instead an honorary rank analogous to the Marshal of France, although without associated state functions. In the Soviet Navy before 1935 the ranks were personal positions. Since that year the general officer rank structure became as follows: Flag officer 2nd rank Flag officer 1st rank Fleet flag Officer 2nd rank Fleet flag Officer 1st rank From 1940, the rank structure for high officers of the Navy became: Captain 1st rank Rear admiral Vice-admiral Admiral In 1943, the rank structure slightly changed into the final rank formation which remained until the dissolution of the Navy in 1991 with more changes in 1955 and 1962: Captain 1st rank Rear admiral Vice-admiral Admiral Admiral of the fleet (became Admiral of the Fleet of the Soviet Union in 1955, reinstated in 1962 as a junior rank equivalent to General of the Army) Ranks in the shore services mirrored the changes in the Red Army save that Colonel-General became the highest rank for troops in those services. The Russian Navy still uses this, except that Marshal of the Russian Federation is the highest rank of precedence, and the rank below that, Admiral of the Fleet, is the highest deck rank for officers.
