Having accumulated 160 confirmed kills out of 255 probable kills, Chris Kyle is is credited as the most lethal sniper in US military history. These numbers are based on individual shooter logs, filled out at the end of a mission, and reported to higher command. Confirmed kills must have a witness.
He was assigned to SEAL Team 3, Sniper Element Charlie platoon within the Naval Special Warfare Command.
Kyle had four tours of duty and served in many major battles of the Iraq War.
His first long-range kill shot was taken during the initial invasion when he shot a woman approaching a group of Marines with a hand grenade in her hand. An article by CNN reported that the woman was cradling a toddler in her other hand.
Because of Kyle's track record as a marksman during his deployment to Ramadi, the insurgents named him "Shaitan Ar-Ramadi".
And he eventually came to have an $80,000 bounty placed on his head. Insurgents posted signs highlighting the cross on his arm as a means of identifying him.
In his book, Kyle claims that his longest successful shot came when he spotted an insurgent with a rocket launcher near a U.S. Army convoy at a range of 2,100 yards.
During four tours of duty in Iraq, Kyle was shot twice and caught up in six separate IED explosions.
Kyle was awarded several commendations for acts of heroism and meritorious service in combat. He received two Silver Star Medals, five Bronze Star Medals, one Navy and Marine Corps Commendation Medal, and two Navy and Marine Corps Achievement Medals.
Kyle was honorably discharged from the US Navy in 2009, and moved to Midlothian, Texas, with his wife, Taya, and two children. His bestselling autobiography, "American Sniper", was published in January 2012.
