There are a great many of U.S. Servicemen in Vietnam who are contributing much toward the success of Allied operations in that country by performing important "behind the scene" roles in support of the war effort.
Among these are the U.S. army enlisted man who are Crew Chiefs on UH-1B Huey helicopters. Commonly known as "slicks" contrasted to the armed aircraft, the Huey helicopters normally are used for airlifting troops in and out of combat areas, making resupply and reconnaissance missions, lifting troops into inaccessible locations, plus many other related missions such as resupplying outlying outposts, flying cover protection for perimeter guards, and flying support in defense of the main road leading into An Khe, where Company A, 229th Helicopter Assault Battalion, 11th Aviation Group of the 1st Air Cavalry Division is headquartered.
Duties of the Crew Chief begin early in the morning and end late at night. Before a mission, it is the responsibility of the Crew Chief to insure that the helicopter is mechanically sound and that all weapons necessary to perform the mission are working and loaded. Following the mission, the Crew Chief must perform post flight checks of the aircraft to insure that there is no damage, then the craft is tied down until the next flight.
During the flight, the Crew Chief monitors the instruments, checks for obstacles in landing zones, and keeps a careful eye on the sling hoist when the aircraft is carrying sling loads. In addition, he often operates a machine gun at one of the side doors of the helicopter when the situation demands.
After a certain number of hours have been flown by the helicopter, specified maintenance must be performed by the Crew Chief.
