on 4 May 1967. Even though the PAVN attack was repelled, damage to the camp was extensive. Since the original site lacked good observation and fields of fire beyond the barbed-wire perimeter, the 5th Special Forces Group commander decided to move the camp to a more suitable area, about 1,000 meters to the west. The new camp, on Highway 9 about to the west of Khe Sanh, was completed in 1967. In 1967, Captain Franklin C. Willoughby assumed command of Detachment A-101 at Lang Vei, which had a tactical area of responsibility of , and was one of nine operational CIDG camps in I Corps Tactical Zone. From Lang Vei, U.S Special Forces personnel worked jointly with a 14-man Army of the Republic of Vietnam (ARVN) special forces contingent and six interpreters; they were responsible for border surveillance, interdiction of enemy infiltration and assistance in the Revolutionary Development Program. To accomplish those tasks Willoughby had one Montagnard company, three South Vietnamese rifle companies and three combat reconnaissance platoons at his disposal. Early in January 1968, Detachment A-101 received reinforcements in the form of a Mobile Strike Force Company, consisting of 161 Hre tribesmen, along with six U.S. Special Forces advisors. Elements of this Mobile Strike Force Company operated from a fortified bunker about 800 meters west of the camp, which served as an observation post. During the day the Hre tribesmen of the Mobile Strike Force conducted patrols; at night they took up ambush positions in the vicinity of the camp. Prior to the battle, Willoughby placed Company 101 of 82 Bru Montagnard tribesmen, on the northeastern flank of the camp, with the 3rd Combat Reconnaissance Platoon positioned just behind it. Company 104 was placed in the southern end of the camp; Company 102, consisting of 42 men, was positioned at the opposite end about 450 meters to the west, while the 43-man Company 103 was positioned further south. The 1st and 2nd Combat Reconnaissance Platoons were placed at the northern and southern perimeters respectively, about 200 meters apart. Individually, the CIDG personnel carried M1 and M2 carbines with nearly 250,000 rounds of ammunition, and each company was also equipped with one 81 mm mortar. Among heavy weapons, there were two 106mm recoilless rifles, two 4.2-inch mortars and nineteen 60 mm mortars positioned around the camp. For close-in support, the CIDG personnel were furnished with 100 disposable M-72 anti-tank weapons.
