On July 11, 1942, the Omsk Regional Committee of the the All-Union Communist Party of Bolsheviks announced, "About the formation of the Stalinist Volunteer Separate Rifle Brigade of the Omsk Siberians."
In the Khanty-Mansiysk National Okrug, which was the main territory of the special settlements, the "voluntary conscription" was held the next day after the adoption of the party resolution. After the labour settlers appeared in the special commandant's offices of the People's Commissariat for Internal Affairs, 1,200 moved to Omsk to the assembly station "Cheryomushki" on steamboats. According to the statistics of the okrug military commissariat, opened on August 30, 1938, until July 12, 1942, only 320 people were conscripted from Ugra to the Red Army, and by the end of 1945, 17,000 people were sent to the front for "special conscription" and 5,174 – to the "labour army".
The 75th Omsk Rifle Brigade became part of the 6th Siberian Volunteer Rifle Corps. In addition to it, the unit included the 150th Novosibirsk Rifle Division (Novosibirsk, Prokopyevsky, Kemerovo Rifle and Tomsk Artillery Regiments), the 74th Altai, 78th Krasnoyarsk and 91st Brigades, also consisting mainly of labour settlers. In the official correspondence of the Special Departments of the People's Commissariat for Internal Affairs, they were called "Spetsdobrovoltsy" [Special Volunteers].
