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 a Bronze Oak Leaf Cluster in lieu of a Second Award of the Silver Star to Lieutenant Colonel Obadiah A. Dugan (AFSN: FR-263837), United States Air Force, for gallantry in connection with military operations against an opposing armed force as an F-105 Pilot of the 357th Tactical Fighter Squadron, Takhli Royal Thai Air Base, Thailand, in action near Bac Giang, North Vietnam, on 1 July 1967. On that date, Colonel Dugan successfully led a strike force of twenty-eight F-105 and F-4C aircraft against the heavily defended Bac Giang rail and highway bridge. After making a direct hit on the bridge, he courageously ignored heavy anti-aircraft fire and maneuvered in the target area to render aid to his number three and four men who experienced aircraft malfunctions during the bomb run. By his gallantry and devotion to duty Colonel Dugan has reflected great credit upon himself and the United States Air Force.
