The Armed Forces of Bosnia and Herzegovina is the official military force of Bosnia and Herzegovina. The BiH armed forces were officially unified in 2005 and are composed of two founding armies: the Bosniak Army of the Federation of Bosnia and Herzegovina (VFBiH) and the Bosnian Serbs' Army of Republika Srpska (VRS).
The Army of Republika Srpska, commonly referred to in English as the Bosnian Serb Army, was the military of Republika Srpska, the self-proclaimed Serb secessionist republic, a territory within the newly independent Bosnia and Herzegovina, which it defied and fought against. Active during the Bosnian War from 1992 to 1995, it continued to exist as the armed forces of RS, one of two entities making up Bosnia and Herzegovina, until 2006 when it was integrated into the Armed Forces of Bosnia and Herzegovina. Forces of the VRS engaged in several campaigns, including Operation Corridor 92, Operation Vrbas '92, Operation Bura, and Operation Spider; they were also involved in the siege of Sarajevo, as well as the Srebrenica massacre.
The Bosnian War was an international armed conflict that took place in Bosnia and Herzegovina between 1992 and 1995. The war is commonly seen as having started on 6 April 1992, following a number of earlier violent incidents. The war ended on 14 December 1995 when the Dayton accords were signed. The main belligerents were the forces of the Republic of Bosnia and Herzegovina, the Republic of Herzeg-Bosnia, and the Republika Srpska, the latter two entities being proto-states led and supplied by Croatia and Serbia, respectively.
Operation Sana was the final military offensive of the Army of the Republic of Bosnia and Herzegovina in western Bosnia and Herzegovina and the last major battle of the Bosnian War. It was launched from the area of Bihać on 13 September 1995, against the Army of Republika Srpska, and involved advances towards Bosanski Petrovac, Sanski Most and Bosanska Krupa. At the same time, the Croatian Army and the Croatian Defence Council were engaging the VRS in Operation Maestral 2 further to the southeast. After an initial 70-kilometre (43 mi) advance, VRS reinforcements managed to stop the ARBiH short of Sanski Most and Novi Grad, and reversed some of the ARBiH's territorial gains in a counterattack. After a part of the ARBiH 5th Corps was threatened with defeat around the town of Ključ, the ARBiH requested assistance from the HV.
Operation Mistral 2, officially codenamed Operation Maestral 2, was a Croatian Army (HV) and Croatian Defence Council (HVO) offensive in western Bosnia and Herzegovina on 8–15 September 1995 as part of the Bosnian War. Its objective was to create a security buffer between Croatia and positions held by the Bosnian Serb Army of Republika Srpska (VRS). The operation also spearheaded a Herzeg-Croat led move to compromise the occupation of the largest Bosnian Serb-held city, Banja Luka, by capturing the towns of Jajce, Šipovo and Drvar. Thus jeopardizing the operations capacity of Banja Luka and ultimately leading to its recapture. The combined HV and HVO forces were under the overall command of HV Major General Ante Gotovina.
The Croat–Bosniak War was a conflict between the Republic of Bosnia and Herzegovina and the Republic of Herzeg-Bosnia, supported by Croatia, that lasted from 18 October 1992 to 23 February 1994. It is often referred to as a "war within a war" because it was part of the larger Bosnian War. In the beginning, the Army of the Republic of Bosnia and Herzegovina and the Croatian Defence Council (HVO) fought together in an alliance against the Yugoslav People's Army (JNA) and the Army of Republika Srpska (VRS). By the end of 1992, however, tensions between Bosniaks and Bosnian Croats increased. The first armed incidents between them occurred in October 1992 in central Bosnia. The military alliance continued until early 1993, when it mostly fell apart and the two former allies engaged in open conflict.
This section is about the history of the Army of the Republic of Bosnia and Herzegovina that existed from 1992 to 1995, then it was formed into two armies of the two entities from 1998 to 2005 and finally transformed into the Armed Forces of Bosnia and Herzegovina (OSBIH).
Operation Corridor 92 was the largest operation conducted during the Bosnian War by the Army of Republika Srpska (VRS) against the forces of the Croatian Defence Council (HVO) and the Croatian Army (HV) in the Bosanska Posavina region of northern Bosnia and Herzegovina between 24 June and 6 October 1992. The objective of the offensive was to re-establish a road link between the city of Banja Luka in the west of the country and the eastern parts of the territory controlled by the Bosnian Serbs. The offensive was prompted by the capture of Derventa by the HV and the HVO – a move that blocked the single overland road between the VRS-controlled territories.
Operation Vrbas '92 was a military offensive undertaken by the Army of Republika Srpska in June–October 1992, during the Bosnian War. The goal of the operation was the destruction of a salient around the central Bosnian town of Jajce, which was held by the Croatian Defence Council and the Army of the Republic of Bosnia and Herzegovina. The intensity of fighting varied considerably and involved several major VRS offensive efforts interspersed by relative lulls in fighting. Jajce fell to the VRS on 29 October 1992, and the town's capture was followed by the destruction of all its mosques and Roman Catholic churches.
Operation Winter '94 was a joint military offensive of the Croatian Army (HV) and the Croatian Defence Council (HVO) fought in southwestern Bosnia and Herzegovina between 29 November and 24 December 1994. The operation formed part of the Croatian War of Independence and the Bosnian War fought between Bosnia and Herzegovina, Croatia and two unrecognized para-states proclaimed by Croatian Serbs and Bosnian Serbs. Both para-states were supported by the Yugoslav People's Army (JNA) and Serbia. The JNA pulled out in 1992, but transferred much of its equipment to the Bosnian Serb and Croatian Serb forces as it withdrew.
The Croat–Bosniak War was a conflict between the Republic of Bosnia and Herzegovina and the Croatian Community of Herzeg-Bosnia, supported by Croatia, that lasted from 19 June 1992 – 23 February 1994. The Croat-Bosniak War is often referred to as a "war within a war" because it was part of the larger Bosnian War.
The Leaders of the Yugoslav Wars listed below comprise the important political and military figures of the Yugoslav wars.
The Siege of Mostar was fought during the Bosnian War first in 1992 and then again later in 1993 to 1994. Initially lasting between April 1992 and June 1992, it involved the Croatian Defence Council (HVO) and the Army of the Republic of Bosnia and Herzegovina (ARBiH) fighting against the Serb-dominated Yugoslav People's Army (JNA) after Bosnia and Herzegovina declared its independence from Yugoslavia. That phase ended in June 1992 after the success of Operation Jackal, launched by the Croatian Army (HV) and HVO. As a result of the first siege around 90,000 residents of Mostar fled and numerous religious buildings, cultural institutions, and bridges were damaged or destroyed.
The Battle of Kupres was a battle of the Bosnian War, fought between the Army of the Republic of Bosnia and Herzegovina (ARBiH) and the Croatian Defence Council (HVO) on one side and the Army of Republika Srpska (VRS) on the other from 20 October to 3 November 1994. It marks the first tangible evidence of the Bosniak–Croat alliance set out in the Washington Agreement of March 1994, brokered by the United States to end the Croat–Bosniak War fought between the ARBiH and the HVO in Bosnia and Herzegovina. The ARBiH and the HVO were not coordinated at first, rather they launched separate operations aimed at capture of Kupres.
The Agreement on Friendship and Cooperation between Bosnia and Herzegovina and Croatia was signed by Alija Izetbegović, President of the Republic of Bosnia and Herzegovina, and Franjo Tuđman, President of the Republic of Croatia, in Zagreb on 21 July 1992 during the Bosnian and Croatian wars for independence from Yugoslavia. It established cooperation, albeit inharmonious, between the two and served as a basis for joint defense against Serb forces. It also placed the Croatian Defence Council (HVO) under the command of the Army of the Republic of Bosnia and Herzegovina (ARBiH).
Operation Una was a military offensive conducted by the Croatian Army against the Army of Republika Srpska in western Bosnia and Herzegovina on 18–19 September 1995, during the Bosnian War. The operation entailed a crossing of the Una and Sava rivers to establish bridgeheads at Novi Grad, Bosanska Dubica, Bosanska Kostajnica and opposite Jasenovac to allow for a subsequent advance towards Prijedor and Banja Luka.
The Battle of Orašje was fought during the Bosnian War, from 5 May to 10 June 1995, between the Bosnian Serb Army of Republika Srpska and the Bosnian Croat Croatian Defence Council for control of the town of Orašje and its surrounding area on the south bank of the Sava River. The offensive codenamed Operation Flame-95 and referred to by Croatian sources as Operation Revenge was actually fought with varying intensity, with periods of combat interspersed by lulls lasting two to seven days. The heaviest fighting was reported on 15 May, when the VRS managed to break through a portion of the HVO defences near the village of Vidovice, but the breach was successfully contained and the lost ground was recovered by the HVO.
Operation Southern Move was the final Croatian Army (HV) and Croatian Defence Council (HVO) offensive of the Bosnian War. It took place in western Bosnia and Herzegovina on 8–11 October 1995. Its goal was to help the Army of the Republic of Bosnia and Herzegovina (ARBiH) whose positions around the town of Ključ, captured by them during Operation Sana, were endangered by a counteroffensive by the Army of Republika Srpska (VRS). The objectives of Operation Southern Move included the capture of the town of Mrkonjić Grad and positions on the Manjača Mountain which would allow the HV and the HVO to directly threaten Banja Luka, the largest city controlled by Bosnian Serbs. Finally, the offensive was also aimed at capturing the Bočac Hydroelectric Power Station, the last significant source of electricity under VRS control in western Bosnia and Herzegovina. The combined HV and HVO forces were under the overall command of HV Major General Ante Gotovina.
The Battle of Bugojno was fought between forces of the Army of the Republic of Bosnia and Herzegovina (ARBiH) and the Croatian Defence Council (HVO) for control of the town and municipality of Bugojno in central Bosnia, from 18–28 July 1993. The area of Bugojno was under joint control of the ARBiH 307th Brigade and the HVO Eugen Kvaternik Brigade since the start of the Bosnian War. Violent incidents in Bugojno followed the escalation of the Croat-Bosniak War in adjacent municipalities throughout the 1st half of 1993. Bugojno was spared from fighting and the two local brigades were still formally allied by June 1993, at the time of an ARBiH offensive in central Bosnia.
Operation Bura was a joint offensive conducted by the Croatian Defence Council and the Croatian Army on the territories held by the Nevesinje and Bileća brigades of the Army of Republika Srpska during the Bosnian War.
