Operation THIEN BO 1/68
Darlac Province, II Corps, South Vietnam
Location, Camp Coryell
Description: The 155th Aviation Company unit history states that at 0245H, Camp Coryell was again attacked with 82mm mortars and ground elements firing B-40 rockets. See separate report concerning the attack. Fortunately no casualties were suffered on the compound, but some 46 enemy rounds destroyed two UH-1H and damaged ten others. Additionally two transient DUSTOFF ships also incurred damage while parked overnight in the corral. Several buildings and vehicles were damaged or destroyed. The company had been poised in readiness to support Operation THIEN BO on the 5th. They spent the 5th repairing sufficient mission ready aircraft to support the operation on the 6th. Both the 165th Transportation Detachment and the 155th Service Platoon again proved their responsiveness and ability to meet this challenge. On the 5th, the company conducted its largest combat assualt in several months. Eleven lift helicopters from the 155th and five from the 92d AHC provided the assault ships; which was in conjunction with Operation THIEN BO 1/68, a joint 23d ARVN Division and 24th Ranger Group operation. Five FALCON UH-1C's were utilized for LZ pre-strikes along with Vietnamese Air Force A-1E's. The gunships provide suppressive fire and continous air cover for the assault operation. A total of 850 troops of the 11th and 22d Ranger Battalions were lifted in 240 sorties. An additional 190 troops from the 1/45 ARVN Regiment were lifted from Ban Bleck into another one-ship LZ which was to be set up as a Fire Support Base. The Pathfinder Detachment worked for several hours clearing this LZ so that four CH-47's from the 180th ASHC could airlift four tubes of 105 howitzers along with necessary ammunition and supplies to establish this base. The 155th Service Platoon provided refueling facilities at both PZs to support the operation. The entire mission was accomplished on time and without incident.
