The Forces of Special Purpose (ChON) (Russian: Части особого назначения) were a military internal security force established by the Bolsheviks during the Russian Civil War.
The Forces of Special Purpose (ChON) were created by a 17 April 1919 declaration of the Central Committee of the Russian Communist Party (Bolsheviks).
Membership was later given to trade union and Komsomol members.
The ChON units typically came under Red Army operational control in areas close to the frontline.
The ChON units were disbanded and merged into the Red Army in 1924.
