The Russian 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
VOKhR)), 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 best-known of the internal troops divisions is
OMSDON based near
Moscow which traces its roots to the "
OSNAZ" detachment of the VChK (formerly
1st Automobile Fighting Detachment of the
VTsIK). It was later reorganized into the DON (Special-Purpose Division) of the
OGPU and the NKVD. These forces were introduced during the Soviet era, initially to provide armed, tactical support for the
militsiya, the equivalent of the major police organizations found in other countries. Over time, internal troops also gained responsibility for safeguarding of highly-important facilities (like
nuclear power plants), large-scale
crowd control and prison security. As such, these forces have been involved in major wars as well as combating insurgencies and other civil unrest, including the
Russian Civil War,
World War II, mass repressions of
Stalinist era, and the
Chechen Wars. During wartime, internal troops fall under
armed forces military command and fulfill the missions of local defence and rear area security.
Internal troops outside Soviet Union . The pattern of internal troops was copied by many countries of the
Warsaw Pact. In 1945 in Poland the
Internal Security Corps was established, in
East Germany a similar unit or the
Volkspolizei-Bereitschaft ("People's Police Alert Units") was created in 1955. These units were created for a further reason as well: to have additional ground troop capacities in the event of a war, that did not show up at armaments negotiations, because those internal troops were not part of the military and still had suitable and compatible equipment. There were also internal troops in Bulgaria. During
Cold War the
West German Bundesgrenzschutz /BGS (Federal Border Guard) was a paramilitary police with infantry units as well, for a short period there was even a
mandatory service in force. == Current deployments ==
