Iraqi Army had amassed around 60,000 troops across the border, near the Kuwaiti town of Wafra, in as many as 5 or 6 divisions. Infantry divisions normally consisted of three brigades with an attached commando unit, although some infantry divisions could have up to eight brigades–however most infantry divisions along the border were understrength, primarily due to desertion. Armored and mechanized divisions normally made use of three brigades, with each brigade having up to four combat battalions; depending on the division type, these were generally a three to one mix, with either three mechanized battalions and one armored battalion, or vice versa. Given the size of the forces deployed across the border, it is thought that the Iraqi Army planned to continue the offensive, after the successful capture of Khafji, in order to seize the valuable oil fields at Dammam. The attack would consist of a four-prong offensive. The 1st Mechanized Division would pass through the 7th and 14th Infantry Divisions to protect the flank of the 3rd Armored Division, which would provide a blocking force west of Khafji while the 5th Mechanized Division took the town. The 1st Mechanized and 3rd Armored divisions would then retire to Kuwait, while the 5th Mechanized Division would wait until the Coalition launched a counteroffensive. The principal objectives were to inflict heavy casualties on the attacking Coalition soldiers and take prisoners of war, who Saddam Hussein theorized would be an excellent bargaining tool with the Coalition. As the units moved to the Saudi Arabian border, many were attacked by Coalition aircraft. Around the Al-Wafrah forest, about 1,000 Iraqi armored fighting vehicles were attacked by Harrier aircraft with Rockeye cluster bombs. Another Iraqi convoy of armored vehicles was hit by A-10s, which destroyed the first and last vehicles, before systematically attacking the stranded remainders. Such air raids prevented the majority of the Iraqi troops deployed for the offensive from taking part in it. Coalition forces During the buildup of forces, the U.S. had built observation posts along the Kuwaiti-Saudi Arabian border to gather intelligence on Iraqi forces. These were manned by U.S. Navy SEALs, U.S. Marine Corps Force Reconnaissance and Army Special Forces personnel. Observation post 8 was farthest to the east, on the coast, and another seven observation posts were positioned each until the end of the "heel", the geographic panhandle of southernmost Kuwait. Observation posts 8 and 7 overlooked the coastal highway
