His 5th Distinguished Flying Cross w/Valor Citation reads:

Captain Marion A. Marshall distinguished himself by heroism while participating in aerial flight as an F-4D Weapon Systems Officer while stationed at Udorn Royal Thai Air Force Base, Thailand, on 16 April 1972. On that date, Captain Marshall participated in a flight of F-4D tactical fighter-bombers on the most important attack mission in four years in the vicinity of Hanoi. Braving extremely hazardous conditions, including surface-to-air missiles, heavy antiaircraft artillery, hostile aircraft, and adverse weather, Captain Marshall courageously attacked and destroyed valuable fuel and associated equipment which was vital to hostile operations. The outstanding heroism and selfless devotion to duty displayed by Captain Marshall reflect great credit upon himself and the United States Air Force.
