In 1990 due to the "Jedinstvo 3" reorganization plan, 781st Transport Helicopter Squadron of same 111th Aviation Brigade was disbanded.

As the war in Croatia intensified, the 111th Aviation 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 three of its helicopter squadrons were re-located to Zalužani near Banja Luka and reorganized in to Helicopter Regiment with two squadrons.

780th Squadron had 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.

On May 12, 1992 111th Helicopter Regiment with its two squadrons became part of newly formed Bosnian Serbs Air Force.

On 26 July 1992, just two months after the initial structure of the Republika Srpska Air Force was established, the flying units were once again reorganized.
