Z-4 Plan once again. The talks were used by Croatia to prepare diplomatic ground for the imminent Operation Storm, whose planning was completed during the Brijuni Islands meeting between Tuđman and military commanders on 31 July. The HV initiated large-scale mobilization in late July, soon after General Zvonimir Červenko became its new Chief of General Staff on 15 July. In 2005, the Croatian weekly magazine Nacional reported that the U.S. had been actively involved in the preparation, monitoring and initiation of Operation Storm, that the green light from President Clinton was passed on by the US military attache in Zagreb, and the operations were transmitted in real time to Pentagon. Order of battle The HV operational plan was set out in four separate parts, designated Storm-1 through 4, which were allocated to various corps based upon their individual areas of responsibility (AORs). Each plan was scheduled to take between four and five days. The forces that the HV allocated to attack the RSK were organised into five army corps: Split, Gospić, Karlovac, Zagreb and Bjelovar Corps. A sixth zone was assigned to the Croatian special police inside the Split Corps AOR, near the boundary with the Gospić Corps. The HV Split Corps, located in the far south of the theatre of operations and commanded by Lieutenant General Ante Gotovina, was assigned the Storm-4 plan, which was the primary component of Operation Storm. The Split Corps issued orders for the battle using the name Kozjak-95 instead, which was not an unusual practice. The 30,000-strong Split Corps was opposed by the 10,000-strong ARSK 7th North Dalmatia Corps, headquartered in Knin and commanded by Major General Slobodan Kovačević. The 3,100-strong special police, deployed to the Velebit Mountain on the left flank of the Split Corps, were directly subordinated to the HV General Staff commanded by the Lieutenant General Mladen Markač. The 25,000-strong HV Gospić Corps was assigned the Storm-3 component of the operation, to the left of the special police zone. It was commanded by Brigadier Mirko Norac, and opposed by the ARSK 15th Lika Corps, headquartered in Korenica and commanded by Major General Stevan Ševo. The Lika Corps, consisting of about 6,000 troops, was sandwiched between the HV Gospić Corps and the ARBiH in the Bihać pocket in ARSK rear, forming a wide but a very shallow area. The ARBiH 5th Corps deployed about 2,000 troops in the zone. The Gospić Corps,
