The President of the United States of America, authorized by Act of Congress July 9, 1918 (amended by an act of July 25, 1963), takes pleasure in presenting the Silver Star to Captain Robert Owen Heavner (AFSN: FR-70066), United States Air Force, for gallantry in action while engaged in military operations involving conflict with an armed hostile force as a B-57 Pilot of the 13th Tactical Bombardment Squadron, in action in Southeast Asia on 15 March 1968. On that date, Captain Heavner flew a successful night interdiction mission against hostile lines of communication and supply routes used to infiltrate men and supplies to hostile forces in the Republic of Vietnam. Despite intense antiaircraft fire directed at his aircraft, Captain Heavner repeatedly attacked a hostile convoy, destroying seven of the heavily laden vehicles, one hostile antiaircraft position and causing ten secondary fires in the target area. By his gallantry and devotion to duty, Captain Heavner has reflected great credit upon himself and upheld the highest traditions of the United States Air Force.
