The Internal Troops, full name Internal Troops of the Ministry for Internal Affairs (MVD) (Russian: Внутренние войска Министерства внутренних дел, Vnutrenniye Voiska Ministerstva Vnutrennikh Del; abbreviated ВВ, VV), alternatively translated as "Interior (Troops or Forces)", is a paramilitary gendarmerie-like force in the now-defunct Soviet Union and in some of its successor countries, including in Russia (until 2016), Ukraine (until 2014), Georgia (until 2004), Azerbaijan and Tajikistan. Internal Troops are subordinated to the interior ministries of the respective countries.
They were designed to be used to support and reinforce the Militsiya, deal with large-scale crowd control, internal armed conflicts, prison security (except in Russia) and safeguarding of highly-important facilities (like nuclear power plants). As such, the force was and is involved in the various conflicts and violent disturbances in the history of the Soviet Union and modern Russia, including the Russian Civil War, World War II, mass repressions of Stalinist era, and the Chechen Wars. During wartime, the Internal Troops falls under armed forces military command and fulfill the missions of local defence and rear area security.
The Soviet Internal Troops were formed in 1919 under the Cheka (later NKVD, and were known as "NKVD Troops", formerly the "Internal Security Forces" (Russian: Voyska vnutrenney okhrany Respubliki or VOHR)), remained there with all the mergers and splittings of Soviet state security services and ended up under the control of the police-like MVD. The most well-known of the Internal Troops divisions is OMSDON based near Moscow which traces its roots to the "OSNAZ" detachment of the VChK (formerly of the VTsIK). It was later reorganized into the DON (Special-Purpose Division) of the OGPU and the NKVD.
