When Gunnery Sergeant Carlos Hathcock arrived in Vietnam with his Winchester Model 70 hunting rifle—a "civilian" weapon many Marines scoffed at—he silenced the doubters by eliminating 7 Viet Cong on his very first mission. Over his tour, this legendary Marine sniper would rack up 93 confirmed kills (with estimates exceeding 300), becoming so feared that the North Vietnamese nicknamed him "White Feather" for the signature plume in his bush hat and dispatched dedicated counter-sniper teams to hunt him down. His most extraordinary feat came when he killed an enemy sniper by shooting directly through the man's riflescope—a shot requiring impossible precision that proved the scope was aimed directly at Hathcock in that split second. This is the story of how one man and his "inferior" rifle became the most hunted—and most lethal—sniper in the Vietnam War.
