OMON Day - a professional holiday for employees of special police units - is celebrated in Russia annually on October 3 in accordance with Order No. 190 "On the announcement of the Day of special police units", signed on March 1, 2002 by the Minister of Internal Affairs of the Russian Federation B. Gryzlov.
OMON stands for Special Purpose Mobile Detachment (previously, until 2011, the Special Purpose Police Detachment).
The date for the holiday was chosen due to the fact that for the first time the special police units of the internal affairs bodies were created in accordance with the Order of the USSR Ministry of Internal Affairs dated October 3, 1988 No. 0206 in three republics that are part of the former USSR (Belarus, Ukraine, Kazakhstan) , and 14 regions of the RSFSR (including the Ministry of Internal Affairs of the Bashkir ASSR, the Internal Affairs Directorate of the Krasnodar, Krasnoyarsk regional executive committees, the Internal Affairs Directorate of the Voronezh, Irkutsk, Kuibyshev, Novosibirsk, Perm, Rostov, Sverdlovsk, Chelyabinsk regional executive committees, the Central Internal Affairs Directorate of the Moscow City Executive Committee, the Moscow Regional Executive Committee, the Lenoblgorispolkoms). By the end of the 1990s, OMON units existed in all regions of Russia.
