The Armed Forces of the Union of Soviet Socialist Republics, also known as the Armed Forces of the Soviet Union, the Red Army (1918–1946) and the Soviet Army (1946–1991), were the armed forces of the Communist Party of the Soviet Union (CPSU), Russian Soviet Federative Socialist Republic (1917–1922) and the Soviet Union (1922–1991) from their beginnings in the Russian Civil War of 1917–1923 to the collapse of the Soviet Union in 1991. In May 1992, Russian president Boris Yeltsin issued decrees forming the Russian Armed Forces, which subsumed much of the Soviet Armed Forces. Multiple sections of the former Soviet Armed Forces in the other, smaller Soviet republics gradually came under those republics' control.
According to the all-union military service law of September 1925, the Soviet Armed Forces consisted of the Red Army, the Air Forces, the Navy, the State Political Directorate (OGPU), and the convoy guards. The OGPU was later made independent and amalgamated with the NKVD in 1934, and thus its Internal troops were under the joint management of the Defence and Interior Commissariats. In 1989, the Soviet Armed Forces consisted of the Strategic Rocket Forces, the Ground Forces, the Air Defence Forces, the Air Forces, and the Navy, listed in their official order of importance.
