A detailed accounting of some of the most significant events in the life and work of Marine Sniper Gunnery Sergeant Carlos Hathcock during the Vietnam War. Carlos Norman Hathcock II was a United States Marine Corps sniper with a service record of 93 confirmed kills. Hathcock's record and the extraordinary details of the missions he undertook made him a legend in the U.S. Marine Corps. Long before Chris Kyle penned American Sniper, Carlos Hathcock was already a legend as the American Sniper of Vietnam. For a sniper, time is irrelevant when you're invisible. Inches can take hours, and kill shots, days. Surrounded by the enemy, a level head is all you have to rely on. And if you're Carlos Hathcock, one of the best that's ever lived, extra bullets won't be needed because it only takes one shot. The rest of The Deadly Shootouts TV Series can be found in Docu-Series.
