With 255 kills, 160 of them officially confirmed by the Pentagon, the retired Navy Seal sniper is the deadliest marksman in US military history.

During the Second Battle of Fallujah alone, when US Marines fought running battles in the streets with several thousand insurgents, he killed 40 people.

His feat blows away the previous American record of 109, set by Army Staff Sgt. Adelbert F. Waldron during the Vietnam war.

Carlos Hathcock, the famed Marine sniper who was the subject of the book ‘One Shot, One Kill,’ killed 93 people as a long-range sniper in Vietnam.
