Imposing an arms embargo on all of the former Yugoslav territories

On 25 September 1991, the United Nations Security Council passed Resolution 713, imposing an arms embargo on all of the former Yugoslav territories. The embargo hurt the Army of Republic of Bosnia and Herzegovina the most because the Republic of Serbia inherited the lion's share of the Yugoslav People Army's arsenal and the Croatian Army could smuggle weapons through its coast. Over 55% of the armories and barracks of the former Yugoslavia were located in Bosnia, owing to its mountainous terrain in anticipation of a guerrilla war had Yugoslavia been invaded, but many of those factories (such as the UNIS PRETIS factory in Vogošća) were under Serb control, and others were inoperable due to a lack of electricity and raw materials.
