Stephen F. Snyder served in the U.S. Marine Corps as a Second Lieutenant with F Company, 2nd Battalion, 4th Marines, 3rd Marine Division during the Vietnam War. A Platoon Commander, he led a relief platoon to the base of a mountain known as "The Rock Pile" in the Quang Tri Province, South Vietnam, to aid the wounded and survivors who had been fighting there. Snyder then formed a line of defense of the survivors and his platoon to hold off a last attack by the North Vietnamese. The defense line held their position, but Snyder was killed in the action on August 25, 1966. He was awarded the Purple Heart and Navy Cross.
