The HV Karlovac Corps, commanded by Major General Miljenko Crnjac, on the left flank of the Gospić Corps, covered the area extending from Ogulin to Karlovac, including Kordun, and executed the Storm-2 plan. The corps was composed of 15,000 troops and was tasked with pinning down the ARSK forces in the area to protect the flanks of the Zagreb and Gospić Corps. It had a forward command post in Ogulin and was opposed by the ARSK 21st Kordun Corps headquartered at Petrova Gora, consisting of 4,000 troops in the AOR (one of its brigades was facing the Zagreb Corps). Initially, the 21st Kordun Corps was commanded by Colonel Veljko Bosanac, but he was replaced by Colonel Čedo Bulat during the evening of 5 August. In addition, the bulk of the ARSK Special Units Corps was present in the area, commanded by Major General Milorad Stupar. ARSK Special Units Corps was 5,000-strong, largely facing the Bihać pocket at the onset of Operation Storm. The ARSK armour and artillery in the AOR outnumbered that of the HV.
