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.
