The Army of Republika Srpska (Serbian: Војска Републике Српске/Vojska Republike Srpske; ВРС/VRS), commonly referred to in English as the Bosnian Serb Army,[5] was the military of Republika Srpska, the self-proclaimed Serb secessionist republic, a territory within the newly independent Bosnia and Herzegovina (formerly part of Yugoslavia), which it defied and fought against.

In 2005 a fully integrated unit of Serbs, Bosniaks, and Croats was deployed to augment the US-led coalition forces in Iraq.

[14][15] The supreme commander of the VRS was General Ratko Mladić,[16] later indicted at the International Criminal Tribunal for the Former Yugoslavia (ICTY) for genocide, as were some other high-ranking Serb officers.

The International Criminal Tribunal for the former Yugoslavia stated that: "In July 1995, the Armed Forces of the Republika Srpska were under the command and control of the Commander-in-Chief, Radovan Karadžić.

The vast majority of the fighting force of the VRS itself was divided into six geographically-based Corps, all subordinate to, and under the command of, General Mladić and, in turn, the Commander-in-Chief, Radovan Karadzic.

Formerly known as Ratno Vazduhoplovstva i Protiv Vazdušna Odbrana Vojske Republike Srpske or RV i PVO RS.
