After the Wehrmacht lost (August 1943) the Battle of Kursk, RONA personnel retreated to the territory of Byelorussia, especially to the Lepel area of Vitebsk, where they became involved in German security operations, committing numerous atrocities against the civilian population. In March 1944 the unit was briefly renamed to Volksheer-Brigade Kaminski (Militia Brigade Kaminski), before being absorbed into the Waffen-SS in June 1944.
