The order of battle of the Croatian Special Police Units in 1991–1995 included up to 30 individual special forces units subordinated to the Ministry of the Interior. The special police was created around the Ministry of the Interior's existing airborne special forces unit following an open revolt of the Croatian Serbs against the Government of Croatia in August 1990. It further developed with the increasing involvement of the Yugoslav People's Army in the conflict, supporting the Croatian Serbs. The conflict escalated into the Croatian War of Independence in 1991. The special police took part in the first clashes of the war in Pakrac and at the Plitvice Lakes. As Croatia had no army, the 3,000-strong special forces became the country's most effective fighting force.

The Croatian War of Independence was an armed conflict fought from 1991 to 1995 between Croat forces loyal to the Government of Croatia—which had declared independence from the Socialist Federal Republic of Yugoslavia (SFRY)—and the Serb-controlled Yugoslav People's Army (JNA) and local Serb forces, with the JNA ending its combat operations in Croatia by 1992.
