Bennett arrived in South Vietnam on January 1, 1969, and was assigned to Bravo Company, 1st Battalion, 14th Infantry in the Central Highlands of Vietnam. The unit began a series of strenuous patrols in the dense, mountainous terrain. On February 9, 1969, the unit came under intense fire, and Bennett risked gunfire to pull at least five wounded men to safety. That evening, his platoon sergeant recommended him for the Silver Star. Over the coming days, Bennett repeatedly put himself in harm's way to tend to the wounded. On February 11, while attempting to reach a soldier wounded by sniper fire, Bennett was gunned down. On April 7, 1970, his posthumous Medal of Honor was presented to his mother and stepfather by President Richard Nixon.
