Sergeant James D. Locker distinguished himself by gallantry in connection with military operations against an opposing armed force as Rescue Specialist on an HH-3E in Southeast Asia on 4 May 1968.  On that date, Sergeant Locker was instrumental in the rescue of two members of a Special Forces team that was in imminent danger of being overrun by the opposing forces that encircled their position in the A Shau Valley area.  Despite intense hostile fire which severely damaged his aircraft, Sergeant Locker, with complete disregard for his own personal safety, effected the rescue of two Special Forces personnel.  By his gallantry and devotion to duty, Sergeant Locker has reflected great credit upon himself and the United States Air Force.
