111th Regiment. Meanwhile, in 1968, the regiment moved from Cerklje to Pleso airport and the 894th Liaison Aviation Squadron was disbanded. New Antonov An-26 cargo aircraft replaced the Skytrains in 1976. The regiment was renamed the 111th Transport Aviation Regiment (Serbo-Croatian: 111. vazduhoplovni transportni puk / 111. ваздухопловни транспортни пук) in 1978. In 1982 it had grown to an Aviation Brigade, with two more new helicopter squadrons, the 711th and 713th squadrons coming under command. They were equipped with domestic-made Soko Gazelles. War period The 111th Aviation Brigade was active from the first days of the war in Slovenia. One Mi-8 was shot down by Slovenian Territorial Defence forces on the afternoon of 27 June 1991, killing all three pilots. As the war in Croatia intensified, the brigade found itself located in hostile territory surrounded by Croatian forces, the High Command of the Yugoslav Air Force ordered the evacuation of its units to safer territory, so the 679th Transport Aviation Squadron moved to Batajnica Air Base and was reattached to the 138th Transport Aviation Brigade; while three helicopter squadrons were re-located to Zalužani near Banja Luka. The 713th Anti-Armored Helicopter Squadron was absorbed by the 711th Anti-Armored Helicopter Squadron; so the Air Brigade, consisting of just two squadrons, the 711st and the 780th, became the 111th Helicopter Regiment on 12 October 1991. The regiment operated in an important role during the early war in Croatia and Bosnia and Herzegovina, being used for the transport of troops, ammunition, the evacuation of civilians, CSAR and MEDEVAC missions. The regiment was withdrawn from the Order of Battle of the Yugoslav People's Army to become part of the newly formed Republika Srpska Air Force on 12 May 1992; it was to be based at Kraljevo-Lađevci Airport. On 26 July 1992, just two months after the initial structure of the Bosnian Serb Air Force was established, the flying units were once again reorganized. The 111th Helicopter Regiment was disbanded, and a new unit designated the 92nd Mixed Aviation Brigade was formed to control both fixed-wing and helicopter squadrons. Later in the same year, the 711th Anti-Armored Helicopter Squadron and the 780th Transport Helicopter Squadrons were merged to create the new unit designated the 89th Mixed Helicopter Squadron. The commanders of the regiment following its re-establishment were: Stanislav Verbić, Drago Mikulandra, Marko Mrvac, Vukadin Živanović, Milorad Božić, Vilko Voljevac, Joviša Andrić, Alojz Hršak, Stefanović, Andrija Veselinović
