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 pride in presenting the Silver Star (Posthumously) to Captain (Armor) John Edward Greene, United States Army, for gallantry in action on 13 March 1972 while serving as Assistant District Senior Advisor, Dong Xuan District, Phu Yen Province, Republic of Vietnam. On this date, Captain Greene was accompanying the Dong Xuan District Chief in a convoy on Route 6B in the area of Chi Thanh Pass, Tuy An District. As the convoy proceeded east, the lead vehicle containing the District Chief was struck by a command detonated mine. Simultaneously, intense B-40, AK-47 and M-79 fire was directed upon the first and second vehicles of the column. Realizing the intensity of the fire and the possibility of a second command detonated mine, Captain Greene, as the driver of the second vehicle, immediately halted and dismounted. While exposing himself continuously to the enemy fire, he valorously returned M-79 fire to the enemy position in support of, and to draw fire away from, the District Chief, who had been wounded in the head and leg. When he had fired the last of his ammunition, he began moving through the enemy fire to get more ammunition at a nearby bridge position. It was then that the enemy appeared from a creek bed on the opposite side of the road and fired small arms rounds, one of which mortally wounded Captain Greene. As a result of Captain Greene’s singularly impressive display of courage, the District Chief was given the precious time needed to reorganize his position and repulse the enemy attack. Captain Greene’s conspicuous gallantry in action was in keeping with the highest traditions of military service and reflects great credit upon himself and the military service.
