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.
