 The region was formally controlled by the HVO, but the HV contributed a substantial force, including commanding officers.The attacks were primarily designed to draw the Army of Republika Srpska (VRS) away from the besieged city of Bihać.The secondary objective was threatening the single direct supply route between Drvar in the Bosnian Serb Republika Srpska and Knin, the capital of the Croatian Serb Republic of Serbian Krajina (RSK).
