Operation Stinger was an offensive undertaken by the forces of the SAO Krajina, an unrecognized Croatian Serb region opposing the Republic of Croatia, against positions held by the Croatian police in the region of Banovina on 26–27 July 1991, during the Croatian War of Independence. It was primarily aimed at police stations in Glina and Kozibrod, as well as police-held positions in a string of villages between the town of Dvor and Kozibrod. In addition to Glina and Kozibrod, heavy fighting took place in the village of Struga, north of Dvor, where Croatian Serb forces employed a human shield consisting of Croat civilians taken from their homes in Struga and the nearby village of Zamlača.

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.
