Formations are those military organisations which are formed from different speciality Arms and Services troop units to create a balanced, combined combat force. The formations only differ in their ability to achieve different scales of application of force to achieve different strategic, operational and tactical goals and mission objectives.
Types of formations in the military organization of the Soviet Armed Forces of 1917-1991 included:
Theatre of Military Operations or theatre of war (TV)
Theatre of military operations (ru:Театр военных действий, TVD, teatr voennykh deistvii) — Strategic Directions were created and maintained at the beginning and at the end of World War II (the Great Patriotic War), and are considered a part of the TVD for the purpose of determining operational directions. During World War II, six strategic direction commands existed as part of the Stavka:Chief command of the troops of the Western Direction (1941–42), replaced by Stavka representative role
Chief command of the troops of the North Western Direction (1941), replaced by Stavka representative role
Chief command of the troops of the North Caucasus Direction (1941–42), replaced by Stavka representative role
Chief command of the troops of the South Western Direction (1941–42), replaced by Stavka representative role
Central Staff of the partisan movement (1942–45)
Chief command of the Soviet troops in the Far East (1945)
In their most modern form, TVDs were established in February 1979 (the Far Eastern) and September 1984 (Western (HQ Legnica), South-Western (HQ Kishinev), Southern (HQ Baku) TVD). Viktor Suvorov gave the above formations the name 'High Commands in the Strategic directions'.
Military district (in the USSR), and group of forces (in Eastern Europe). These peacetime administrative units would provide support to between one and six fronts during wartime. Groups of forces in Eastern Europe included the Central Group of Forces (Czechoslovakia), the Group of Soviet Forces in Germany, the Northern Group of Forces (Poland), and the Southern Group of Forces (Balkans initially, then Hungary).
Front — the largest wartime field formation, equivalent to an army group in many other forces. (The Imperial Russian Army designated fronts in World War I; the Soviets used the concept from the Russian Civil War of 1917-1922 onwards.)
Army — the largest peacetime field formation. Each was designated a combined arms army or a tank army. During World War II, the Fortified Region usually corresponded to an Army frontage formation. See Karelian Fortified Region and Kiev Fortified Region.
Corps — Rifle, Cavalry, Artillery, Mechanised, Tank, Aviation and Aviation of PVO, and Airborne Corps.
Rifle Corps - formations that existed in the pre-Revolution Imperial Russian Army - were inherited by the Red Army. First suggestions for creation of large mechanised or tank formations in the Soviet Union were suggested based on development of doctrine for publication as PU-36, the field regulations largely authored by Marshal Mikhail Tukhachevsky, and was created where "In the attack tanks must be employed in mass", envisaged as "Strategic cavalry". Although the name of "mechanised" may seem to the modern reader as referring to the infantry components of the Corps, in 1936 they referred to armoured vehicles only with the word "motorised" referring to the units equipped with trucks.
Division — originally rifle or cavalry, later motor-rifle, tank, artillery, aviation, sapper or airborne. See divisions of the Soviet Union 1917-1945, list of Soviet Army divisions 1989-91
