The Fifth Corps was one of seven corps in the Army of the Republic of Bosnia and Herzegovina. The formation was around the Bihać pocket to protect it against the surrounding Serb forces. The Fifth Corps also fought secessional Muslim forces loyal to Fikret "Babo" Abdić, who was cooperating with Serb and Croat forces. In the last military action of the ARBIH, Operation "Sana 95", the corps defeated Abdić's supporters and brought a number of regions of Bosnia and Herzegovina under government control.
