American Sniper â€“ Trailer â€“ Official UK Warner Bros. - YouTube Christopher Scott "Chris" Kyle (April 8, 1974 â€“ February 2, 2013) was a United States Navy SEAL and the most lethal sniper in American military history with 160 confirmed kills out of 255 claimed kills. Kyle's claims are based on individual shooter logs. U.S. Special Operations Command treats sniper kill counts as "unofficial". Longest shot - In 2008, outside Sadr City, Kyle made his longest successful shot, after he spotted an insurgent with a rocket launcher near a US Army convoy at a range of 2,100 yards (1.9 km). Again, as recounted in his book American Sniper, Kyle fired a shot from his .338 Lapua Magnum-chambered McMillan TAC-338 sniper rifle, killing the insurgent from about 2,100 yards away. The fighter was about to launch a rocket-propelled grenade at the Army convoy. During four tours of duty in Iraq, Kyle was shot twice and caught up in six separate IED explosions. Kyle was honorably discharged from the US Navy in 2009. On Saturday, February 2, 2013, Kyle and a companion, Chad Littlefield, were shot and killed at the Rough Creek Ranch-Lodge-Resort shooting range in Erath County, Texas by 25-year-old fellow veteran Marine Eddie Ray Routh, whom Kyle and Littlefield had purportedly taken to the gun range in an effort to help him with what they were told by his mother was post traumatic stress disorder.
