His Distinguished Flying Cross w/Valor Citation reads:

Captain Hal K. Wilson III distinguished himself by heroism while participating in aerial flight as a B-52 Aircraft Commander near Hanoi, North Vietnam, on 19 December 1972. On that date, Captain Wilson participated in a high-priority bombing mission against a vital military target in a heavily-defended area of North Vietnam. Despite the intensity of defensive reaction and extreme hazards posed by numerous surface-to-air missiles and hostile interceptors, Captain Wilson displayed a courageous willingness to place the mission above his personal safety in directing his aircraft to a successful release of his ordnance on the designated target. The outstanding heroism and selfless devotion to duty displayed by Captain Wilson reflect great credit upon himself and the United States Air Force.
