being dispersed following conflicts with Partisan and German forces during the First Enemy Offensive, Chetnik troops in the area came to an understanding with Nedić. As "legalized" Chetnik formations, they collaborated with the quisling regime in Belgrade, while nominally remaining part of the Mihailović Chetniks. As military conditions in Serbia deteriorated, Nedić increasingly cooperated with Chetnik leader Draža Mihailović. Over the course of 1944 Chetniks assassinated two high-ranking Serbian military officials who had obstructed their work. Brigadier-general Miloš Masalović was murdered in March, while rival Chetnik leader Pećanac was killed in June. Police At the beginning of the occupation, the Military Commander in Serbia was provided with a Security Police Special Employment Squad () consisting of detachments of Gestapo, criminal police and the SD or Security Service (). Initially commanded by SS and Police Leader () Standartenführer und Oberst der Polizei Wilhelm Fuchs, this group was technically under the control of the chief of the Military Administration in Serbia, Harald Turner, but in practice reported direct to Berlin.

The autonomous area of the Banat was a multi-ethnic area with a total population of 640,000, of which 280,000 were Serbs, 130,000 were Germans, 90,000 were Hungarians, 65,000 Romanians, 15,000 Slovaks and 60,000 of other ethnicities.
