During the Kosovo War (1998–1999), he led a cluster of counter-terrorism teams that were known as the Operational Group (OPG).
They were established to counter Kosovo Liberation Army which sought to separate Kosovo from Serbia.
The OPG were later suspected of killing 41 ethnic-Albanian civilians in the Ćuška massacre in western Kosovo in May 1999.

A number of human rights groups have claimed that the OPG committed war crimes against civilians.
Radosavljević was the person in charge of the military operation in Račak on 15 January 1999, which would become known as the Račak massacre.
The Serbian War Crime's prosecutor also brought him in connection with the killing of the Bytyqi brothers, three Albanian American brothers who came to Kosovo to fight on the side of the KLA.
Radosavljević was in charge of a Serb police training facility at Petrovo Selo where the Bytyqi brothers were detained, tortured, executed, and buried in a mass grave.
In December 2018, US State Department issued sanctions on Radosavljević after credibly implicating him in the 1999 murder of the Bytyqi brothers.
