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 Major Robert Frank Pheiff (AFSN: 0-27378), United States Air Force, for gallantry in action while engaged in military operations involving conflict with an armed hostile force in the Republic of Vietnam. Major Pheiff distinguished himself by exceptionally valorous actions while serving as Pilot of a UC-123 Aircraft of the 12th Special Operations Squadron, 315th Air Commando Wing, SEVENTH Air Force, in action against the enemy near Chu Lai, Republic of Vietnam, on 20 July 1968. Major Pheiff led a flight of unarmed UC-123 aircraft on a low-level defoliation mission against a heavily defended hostile base camp, communications center, and crop area. Despite intense and accurate ground fire which raked his aircraft, Major Pheiff tenaciously held his formation on target, and as a result of his courageous efforts, the defoliant was placed precisely on target and hostile ground forces were deprived of valuable ground cover. The gallant actions and dedicated devotion to duty demonstrated by Major Pheiff, without regard for his own life, were in keeping with the highest traditions of military service and reflect great credit upon himself and the United States Air Force.
