Elite and highly trained, the 3d Force Recon's eight-man teams were assigned to obtain vital information about NVA operations. Alone, the men of these small teams were sent behind enemy lines, where they all knew that a single mistake could cost everyone their lives.

United States Navy Hospital Corpsman Bruce Norton was the only navy corpsman to act as a Marine Force Recon Team Leader. In Force Recon Diary, 1969 Doc Norton chronicles his life, mission by mission, with the 3d Force Recon in the DMZ and the A Shau Valley. He describes the tense patrols, the supreme courage, the sacrifices—in ambushes and hot landing zones—that made this courageous company one of only two Marine units during the entire Vietnam War to receive the United States Army's Valorous Unit Citation.
