Русский корпус
Foremost among these was the Serbian Volunteer Corps, largely composed of paramilitaries and supporters of the fascist Yugoslav National Movement (ZBOR) of Ljotić (hence the nickname "Ljotićevci"). Founded in 1941, the formation was initially called "Serbian Volunteer Command", but was reorganized in 1943 and renamed the "Serbian Volunteer Corps", with Kosta Mušicki as the operational leader. At the end of 1944, the Corps and its German liaison staff were transferred to the Waffen-SS as the Serbian SS Corps and comprised a staff from four regiments each with three battalions and a training battalion. The Russian Corps was founded on 12 September 1941 by white Russian emigres, and remained active in Serbia until 1944.
