Luka Džanko. Opposite the Bjelovar Corps was a part of the ARSK Banija Corps. The Bjelovar Corps was included in the attack on 2 August and were therefore not issued a separate operations plan. The ARSK divided its forces in the area in two, subordinating the North Dalmatia and Lika Corps to the ARSK General Staff, and grouping the rest into the Kordun Operational Group commanded by Lieutenant Colonel General Mile Novaković. Territorially, the division corresponded to the North and South sectors of the UN protected areas. Estimates of the total number of troops deployed by the belligerents vary considerably. Croatian forces have been estimated from under 100,000 to 150,000, but most sources put the figure at about 130,000 troops. ARSK troop strength in the Sectors North and South was estimated by the HV prior to Operation Storm at approximately 43,000. More detailed HV estimates of the manpower by individual ARSK corps indicated 34,000 soldiers, while Serb sources quote 27,000 troops. The discrepancy is usually reflected in literature as an estimate of about 30,000 ARSK troops. The ARBiH deployed approximately 3,000 troops against the ARSK positions near Bihać. In late 1994, the Fikret Abdić-led Autonomous Province of Western Bosnia (APWB)—a sliver of land northwest of Bihać between its ally RSK and the pocket—commanded 4,000–5,000 soldiers who were deployed south of Velika Kladuša against the ARBiH force.

UN peacekeepers, known as United Nations Confidence Restoration Operation (UNCRO), were notified three hours in advance of the attack when Tuđman's chief of staff, Hrvoje Šarinić, telephoned UNCRO commander, French Army General Bernard Janvier. In addition, each HV corps notified the UNCRO sector in its path of the attack, requesting written confirmations of receipt of the information. The UNCRO relayed the information to the RSK, confirming the warnings RSK received from the Yugoslav Army General Staff the previous day. Sector South In the Split Corps AOR, at 5 a.m. the 7th Guards Brigade advanced south from Bosansko Grahovo towards the high ground ahead of Knin after a period of artillery preparation.
