[1] ODON (Russian: ОДОН) is an initialism for Отдельная дивизия оперативного назначения (Otdel'naya diviziya operativnogo naznacheniya, English: Separate Operational Purpose Division).

The precursor to the ODON was the 1st Automobile Fighting Detachment of the VTsIK (Russian: 1-й автобоевой отряд) which was created in February 1918.

In April 1921, VChK created the OSNAZ battalion which consisted of 1st Armored Car Detachment, three rifle platoons, a cavalry squadron, and various auxiliary units, with a total strength of some 1,100 men.

With the onset of World War II, parts of the division participated in the Battle of Moscow; the remaining unit guarded particularly important installations of the capital, patrolled the streets, and were involved in efforts to liquidate enemy infiltrator groups near the front and in the city.

Along with participation in hostilities, division elements in Moscow detained 485 enemy intelligence agents, 69,753 deserters, and over 320,000 offenders of the established regime.
