Lieutenant Jack C. Rittichier, United States Coast Guard, distinguished himself by gallantry in connection with military operations against an opposing armed force as Rescue Crew Commander of an HH-3E helicopter in Southeast Asia on 9 June 1968.  On that date, Lt. Rittichier attempted the rescue of a downed pilot from one of the most heavily defended areas in Southeast Asia.  Despite intense accurate hostile fire which had severely damaged another helicopter, Lt. Rittichier, with undaunted determination, indomitable courage, and professional skill, established a hover and persisted in the rescue attempt until his aircraft was downed by the hostile fire.  By his gallantry and devotion to duty, Lt. Rittichier reflected great credit upon himself and the United Station Coast Guard.
