Staff Sergeant Michael F. Dean distinguished himself by gallantry in connection with military operations against an opposing armed force in Southeast Asia on 30 June 1970.  On that date, Sergeant Dean, an HH-53C Pararescue/Recovery Specialist, twice penetrated an area of known hostile concentration in a valiant effort to rescue an injured American pilot.  Undaunted after being repelled during the first attempt, and with complete disregard for his personal safety, he elected to make a second attempt.  As the helicopter neared the downed airman, it sustained severe battle damage, resulting in an uncontrollable fire.  Bravely returning the hostile fire until the end, Sergeant Dean lost his life while trying to save another’s when the helicopter impacted the ground and exploded.  By his gallantry and devotion to duty in the dedication of his service to his country, Sergeant Dean has reflected great credit upon himself and the United States Air Force.
