Soviet Armed Forces

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.

In the Soviet Union, general conscription applied, which meant that all able-bodied males aged eighteen and older were drafted into the armed forces. International observers regarded the armed organizations as collectively one of the strongest such forces in world history. The relative advancement and development of the government's militaries was a key part of the history of the Soviet Union.

In the context of the Cold War, an academic study by the rival U.S. Department of Defense in 1984 found that the Soviets maintained a notable reach across the world and particularly inside Europe. The analysis explicitly concluded that "Soviet armies have always been massive" while "they are also highly modernized, well-equipped, and have great firepower... [as well as] mobility", which meant that "manpower and materiel combined make the present Soviet ground forces a very formidable land army." Although Soviet military strategy in general merited comment, "the ground forces constituted the largest of the five Soviet military services" as of the date the research ended.

The Council of People's Commissars set up the Red Army by decree on January 15, 1918 (Old Style) (January 28, 1918), basing it on the already-existing Red Guard. The official Red Army Day of February 23, 1918, marked the day of the first mass draft of the Red Army in Petrograd and Moscow and the first combat action against the rapidly advancing Imperial German Army. February 23 became an important national holiday in the Soviet Union, later celebrated as "Soviet Army Day", and it continues as a celebration day in present-day^[update] Russia as Defenders of the Motherland Day. Credit as the founder of the Red Army generally goes to Leon Trotsky, the People's Commissar for War from 1918 to 1924.

At the beginning of its existence, the Red Army functioned as a voluntary formation, without ranks or insignia. Democratic elections selected the officers. However, a decree of May 29, 1918, imposed obligatory military service for men of ages 18 to 40. To service the massive draft, the Bolsheviks formed regional Military commissariats (voenkomats), which still carry out this function in Russia. They should not be confused with military political commissars. Democratic election of officers was also abolished by decree, while separate quarters for officers, special forms of address, saluting, and higher pay were all reinstated.

After General Aleksei Brusilov offered the Bolsheviks his professional services in 1920, they decided to permit the conscription of former officers of the Imperial Russian Army. The Bolshevik authorities set up a special commission under the chair of Lev Glezarov (Лев Маркович Глезаров), and by August 1920 had drafted about 315,000 ex-officers. Most often they held the position of military advisor (voyenspets: "военспец" an abbreviation of "военный специалист", i.e., "military specialist"). A number of prominent Red Army commanders had previously served as Imperial Russian generals. In fact, a number of former Imperial military men, notably a member of the Supreme Military Council, Mikhail Bonch-Bruevich, had joined the Bolsheviks earlier.

The Bolshevik authorities assigned to every unit of the Red Army a political commissar, or politruk, who had the authority to override unit commanders' decisions if they ran counter to the principles of the Communist Party of the Soviet Union. Although this sometimes resulted in inefficient command, the Party leadership considered political control over the military necessary, as the Army relied more and more on experienced officers from the pre-revolutionary Tsarist period.
