For extraordinary heroism in connection with military operations involving conflict with an armed hostile force in the Republic of Vietnam, while serving with Detachment A-341, 5th Special Forces Group (Airborne), 1st Special Forces. Sergeant First Class Williams distinguished himself by exceptionally valorous actions on 14 January 1967 while serving as senior Special Forces Advisor to a Vietnamese strike force conducting a search and destroy mission near the Cambodian border. When the unit received an intense barrage of machine gun fire from a North Vietnamese battalion, Sergeant Williams immediately rushed to the forward position and organized a perimeter defense. Although the enemy was at a more advantageous position, Sergeant Williams commanded and led a fierce attack that overcame the enemy emplacements. He then consolidated his position, directed the recovery of the casualties and called for air support. On one occasion, two Vietnamese soldiers were forced to abandon a wounded man due to enemy fire. Observing this Sergeant Williams fearlessly charged the enemy position and single-handedly overpowered its occupants. Still receiving enemy fire, he went to the aid of the wounded soldier and carried him to safety. Sergeant First Class Williams’ extraordinary heroism and devotion to duty were in keeping with the highest traditions of the military service and reflect great credit upon himself, his unit, and the United States Army.
