recruit training with the 1st Recruit Training Battalion, Recruit Training Regiment,

3rd Battalion 7th Marines in the "Arizona Territory" northwest of
An Hoa Combat Base, his 15-man reconnaissance patrol was attacked by a platoon-sized enemy force on Hill 146 in the Quan Duc Duc Valley. When a hand grenade landed in the
fighting hole he shared with fellow Marines, he yelled a warning and immediately hurled his body over the explosive charge. Absorbing the full impact of the blast, he was
killed instantly. His heroic actions on that day were recognized with a posthumous award of the
United States' highest military decoration, the Medal of Honor. ==Decorations and honors==
