Created through the merger of the Territorial Defense of the Republika Srpska Krajina (TORSK), units of the Yugoslav People's Army (JNA) and the Krajina Militia, the Krajina Serb Army was officially established on 19 March 1992. Responsible for the security of the RSK, its area of responsibility covered an area of some 17,028 km² at its peak, as it was located entirely inland it thus had no naval forces. The Serbian Army of Krajina, along with the state of RSK, ceased to exist in 1995 following the Croatian military offensive Operation Storm.
