Carlos Norman Hathcock II (20 May 1942 – 23 February 1999) was a United States Marine Corps sniper with a service record of 93 confirmed kills. During the Vietnam War, kills had to be confirmed by an acting third party, who had to be an officer, besides the sniper’s spotter. Snipers often did not have an acting third party present, making confirmation difficult, especially if the target was behind enemy lines, as was usually the case. Hathcock himself estimated that he had killed 300 or more enemy personnel during his time in Vietnam. Hathcock’s record and the extraordinary details of the missions he undertook made him a legend in the Marine Corps. His fame as a sniper and his dedication to long-distance shooting led him to become a major developer of the United States Marine Corps Sniper training program. He was honored by having a rifle named after him: a variant of the M21 dubbed the Springfield Armory M25 White Feather, for the name “White Feather Sniper” assigned to him by the North Vietnamese Army.
