Christopher Scott "Chris" Kyle was a United States Navy SEAL and the most lethal sniper in U.S. military history with 160 confirmed kills. Kyle served four tours in the Iraq Warand 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, two Navy and Marine Corps Achievement Medals  and numerous other unit and personal awards.

Kyle was honorably discharged from the U.S. Navy in 2009 and wrote a bestselling autobiography, American Sniper, which was published in January 2012.

On February 2, 2013, Kyle was shot and killed at a shooting range near Chalk Mountain, Texas, along with friend Chad Littlefield. The man accused of killing them is awaiting trial for murder. A film adaptation of Kyle's autobiography, directed by Clint Eastwood, was released in December 2014.

Kyle was born in Odessa, Texas, the son of Deby Lynn (née Mercer) and Wayne Kenneth Kyle, a Sunday school teacher and a deacon.

Kyle's father bought his son his first rifle at eight years old, a bolt-action .30-06 Springfield rifle, and later a shotgun, with which they hunted pheasant, quail, and deer. Kyle attended high school in Midlothian, Texas.

After school, Kyle became a professional bronco rodeo rider and worked on a ranch, but his profession ended abruptly when he severely injured his arm.

After his arm healed, Kyle went to a military recruiting office, interested in joining the U.S. Marine Corps with a special interest in special operations. Kyle signed up, but was rejected because of the pins in his arm. Kyle met with a U.S. Army recruiter next, who told him about the Special Forces and the Rangers.

Assigned to SEAL Team 3, sniper element, platoon "Charlie" (later "Cadillac"), within the Naval Special Warfare Command, and with four tours of duty, Kyle 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 while carrying a hand grenade. An article by CNN reported that the woman was cradling a toddler in her other hand. As ordered, he opened fire, killing the woman before she could attack.

 He later stated, "the woman was already dead. I was just making sure she didn't take any Marines with her."

Because of his track record as a marksman during his deployment to Ramadi, the insurgents named him Shaitan Ar-Ramadi (English: 'The Devil of Ramadi'), and put a $21,000 bounty on his head that was later increased to $80,000. They posted signs highlighting the cross on his arm as a means of identifying him.

 In 2008, outside Sadr City, Kyle reportedly made his longest successful shot after spotting an insurgent who was about to fire a grenade at the U.S. Army convoy. Kyle stated that he fired one shot from hisMcMillan Tac-338 sniper rifle from about 2,100 yards (1,920 m) away, killing the insurgent.

During four tours of duty in the Iraq War, Kyle was shot twice and survived six separate IED explosions.

 He accumulated 160 confirmed kills out of 255 probable kills. These numbers are based on individual shooter logs, filled out at the end of a mission, and reported to higher command. Kyle stated that he did not know his official kill record, and only counted the lives he felt he could have saved. U.S. Special Operations Command treats sniper kill counts as "unofficial".Confirmed kills must have a witness.

His other weapons included the Mk 11 7.62×51mm NATO semi-automatic sniper rifle, the Mk 12 5.56×45mm NATO Designated Marksman Rifle, the SIG Sauer P220 pistol, an M4 carbine and a .300 Winchester Magnum-chambered sniper rifle.

 He became known by the moniker "Legend" among the general infantry and Marines whom he was tasked to protect. This title initially originated in jest among fellow SEALs following his taking of a sabbatical to train other snipers in Fallujah.

Kyle left the U.S. Navy in 2009 and moved to Midlothian, Texas, with his wife, Taya, and two children. He was president of Craft International, a tactical training company for the U.S. military and law enforcement communities.

In 2012, HarperCollins released Kyle's autobiographical book American Sniper. Kyle had initially hesitated to write the book but was persuaded to move forward because other books about SEALs were underway.

 In his book, Kyle wrote bluntly of his experiences. Of the battle for control of Ramadi he says

"Force moved that battle. We killed the bad guys and brought the leaders to the peace table. That is how the world works."

 In the book and in interviews following, Kyle stated he had no regrets about his work as a sharpshooter, saying, "I had to do it to protect the Marines."

 American Sniper had a 37-week run on The New York Times bestseller list and brought Kyle national attention. Following its release, media articles challenged some of Kyle's anecdotes, but the core of his narrative was widely accepted. "Tales of his heroism on the battlefield were already lore in every branch of the armed forces."

Kyle paired with FITCO Cares Foundation, a nonprofit organization which created the Heroes Project to provide free in-home fitness equipment, individualized programs, personal training, and life-coaching to in-need veterans with disabilities, Gold Star families, or those suffering from posttraumatic stress disorder.

 On August 13, 2012, Kyle appeared on the reality television show Stars Earn Stripes, which features celebrities pairing up with a special operations or law enforcement professional who train them in weapons and combat tactics. Kyle was teamed with actor Dean Cain.

In interviews on The Opie and Anthony Show in January 2012, Kyle claimed to have punched former Minnesota Governor Jesse Ventura at a bar in Coronado, California, in 2006 during a wake for Mike Monsoor, a U.S. Navy SEAL and Medal of Honor recipient killed in Iraq. The story parallels an incident in his book which does not mention Ventura by name, and claims a character named "Scruff Face" said that the SEALs "deserved to lose a few guys." Ventura filed a lawsuit against Kyle for defamation in January 2012.

 After Kyle was killed the following year Ventura continued the lawsuit against Kyle's estate.

 The court found that Kyle had falsely depicted Ventura in his book and in July 2014 the court awarded Ventura $1.8 million in damages.

Kyle's widow is appealing the verdict on behalf of Kyle's estate.

Death

On 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.

The suspected shooter is a 25-year-old U.S. Marine Corps veteran from Lancaster, Texas, Eddie Ray Routh, whom Kyle and Littlefield had reportedly taken to the gun range in an effort to help him with his personal problems. Routh had been in and out of mental hospitals for at least two years and had been diagnosed with schizophrenia. His family said he also suffered from post-traumatic stress disorder from his time in the military. After the killings, Routh went to his sister's house in Midlothian and told her what he had done.

His sister, Laura Blevins, called 911 saying: "They went out to a shooting range... Like, he's all crazy. He's [expletive] psychotic."

Local police captured Routh after a short freeway chase, which ended when Routh, who had left the scene of the shootings in Kyle's Ford F-350 truck, crashed into a police cruiser in Lancaster.

A memorial service was held for Kyle at Cowboys Stadium in Arlington, Texas on February 11, 2013. Kyle was buried on February 12, 2013, at the Texas State Cemetery in Austin, after a funeral procession from Midlothian to Austin, stretching over 200 miles. Hundreds of people lined Interstate 35 to view the procession and pay their final respects to Kyle.

Routh was arraigned February 2, 2013, on two counts of capital murder and was taken to the Erath County Jail for holding under a $3 million bond. His trial was set to begin May 5, 2014, but was delayed to allow more time to comply with DNA test requirements. 

The trial began on February 11, 2015.
