Marshal of the Soviet Union (Russian: Маршал Советского Союза, romanized: Marshal sovetskogo soyuza, pronounced [ˈmarʂəl sɐˈvʲetskəvə sɐˈjuzə]) was the second-highest military rank of the Soviet Union. It was de facto the highest rank because its superior rank, Generalissimo, was only applied to Joseph Stalin, who preferred to wear the uniform and insignia of Marshal after World War II.
The rank of Marshal of the Soviet Union was created in 1935 and abolished in 1991 when the Soviet Union dissolved. Forty-one people held this rank. The equivalent naval rank was until 1955 admiral of the fleet and from 1955 Admiral of the Fleet of the Soviet Union.
