in Slovenia on 27 June 1991 during the Ten-Day War. The members of Slovenian Territorial Defence fired Strela 2 MANPAD, and shot one helicopter down, killing all crew and passengers. During combat in the winter of 1991 in the Croatian war and in the spring of 1992 in the Bosnian War, the Yugoslav People's Army used the Mi-8 fleet for the evacuation of injured personnel, transport of cargo and search and rescue for the crews of aircraft forced down. As most flights were made behind the front, the Croatian forces were able to down just one helicopter, which was hit by small arms fire near Slavonski Brod on 4 October 1991. After Bosnian Serbs declared their state in the spring of 1992, some former Yugoslav Air Force Mi-8s continued service with the Republika Srpska armed forces. The inventory of the 82nd mixed helicopter squadron, of the 92nd aviation brigade of the Army of Republika Srpska comprised 12 Mi-8T helicopters, which continued in service until Operation Koridor. During that period, the Republika Srpska Air Force lost three Mi-8 helicopters to enemy fire.

A further 6 Mi-8T and 18 Mi-8MTV-1 helicopters were bought from ex-Warsaw Pact countries during the war, but only 16 of those survived the war. The remaining Mi-8Ts were retired from service in the Croatian Air Force after the war, while the Mi-8MTVs continued their service in 20th Transport Helicopter Squadron and 28th Transport Helicopter Squadron. The latter has been re-equipped with new Mi-171Sh helicopters bought from Russia. The Army of the Republic of Bosnia and Herzegovina secretly obtained Mi-8T, Mi-8MTV and Mi-17 helicopters from various sources. Two helicopters were shot down by Serb air defenses, one around Žepa, while one Mi-17 was shot down by 2K12 Kub M, killing the Bosnian Foreign Affairs Minister Irfan Ljubijankić, a few
