It was one of three armed groups, besides the Chetniks and Yugoslav Partisans, that operated in Sandžak during the Second World War and engaged in violent internecine fight. Moslem militia participated in the suppression of the Uprising in Montenegro, committing numerous crimes against Serbs of Montenegro. After the suppression of the uprising this militia continued to fight against Yugoslav Partisans, but some of its units also carried on with attacks on Serbs in Sandžak and eastern Herzegovina. According to German and Croatian sources, the size of Muslim militia in April 1943 was between 8,000 and 12,000 men.
