 In a magnificent display of courage, Specialist Johnson exited the tank and again armed only with a .45 caliber pistol, he engaged several North Vietnamese troops in close proximity to the vehicle.Fighting his way through devastating fire and remounting his own immobilized tank, he remained fully exposed to the enemy as he bravely and skillfully engaged them with the tank's externally-mounted .50 caliber machine gun; where he remained until the situation was brought under control.Specialist Johnson's profound concern for his fellow soldiers, at the risk of his life above and beyond the call of duty are in keeping with the highest traditions of the military service and reflect great credit upon himself and the United States Army.
