The President of the United States of America takes pleasure in presenting the Distinguished Flying Cross to Gunnery Sergeant William H. Cox, United States Marine Corps, for heroism and extraordinary achievement in aerial flight while serving with Marine Observation Squadron TWO (VMO-2), Marine Aircraft Group Sixteen, First Marine Aircraft Wing in connection with combat operations against the enemy in the Republic of Vietnam. On 18 December 1968, Gunnery Sergeant Cox was the Aerial Gunner aboard an armed UH-1E helicopter assigned to support an emergency medical evacuation mission deep in hostile territory. Arriving over the designated area, he quickly located the friendly unit, and positioning his machine gun, delivered effective suppressive fire against enemy positions. When the CH-46 transport helicopter was unable to land in the confined area, Gunnery Sergeant Cox assisted in maneuvering his small gunship into a precarious landing on a ledge jutting over the zone and quickly prepared for the evacuation. With complete disregard for his own safety, he unhesitatingly moved out of the helicopter and carried the critically wounded Marine aboard. As his helicopter lifted out of the perilous zone and proceeded to a nearby hospital ship, Gunnery Sergeant Cox worked tirelessly as he administered lifesaving first aid to his wounded companion. His heroic actions inspired all who served with him and contributed immeasurably to the accomplishment of the hazardous mission. Gunnery Sergeant Cox’s courage, bold initiative and selfless devotion to duty at great personal risk were in keeping with the highest traditions of the Marine Corps and of the United States Naval Service.
