Published in 2012, American Sniper: The Autobiography of the Most Lethal Sniper in U.S. Military History is a military memoir by Chris Kyle, written with Scott McEwen and Jim DeFelice. The book chronicles Kyle’s life, from his Texas upbringing to his career as a US Navy SEAL, detailing his four combat deployments in the Iraq War. As the most lethal sniper in American military history, Kyle recounts his battlefield experiences in key urban conflicts in Iraq, including Fallujah and Ramadi, while also exploring the immense strain his career placed on his marriage and family. The memoir examines themes of “Warrior” Ethics and the Justification of Killing, The Role of Faith and Patriotism in Identity, and The Effects of War on Family Life. Before its publication, the manuscript was reviewed by the US Department of Defense.

The book was an immediate commercial success, becoming a #1 New York Times bestseller and sparking widespread public debate over the morality of modern warfare and its psychological toll on soldiers. The book’s unapologetic tone and Kyle’s stark descriptions of killing divided audience opinion. The memoir’s cultural impact was amplified by a highly successful 2014 film adaptation, American Sniper, directed by Clint Eastwood and starring Bradley Cooper. The film was a major box office hit and received six Academy Award nominations, including for Best Picture. A year after the book’s publication and before the film’s release, Kyle was killed by a fellow veteran he was trying to help, an event that cemented his status posthumously as a prominent and polarizing figure of the Iraq War.

Plot Summary

In March 2003, during his first deployment in Iraq, Navy SEAL Chris Kyle provides sniper overwatch for a Marine unit near Nasiriya. He spots an Iraqi woman on a deserted street who pulls out a grenade as the Marines approach. Following his chief’s order, Kyle shoots her. This is his first kill with a sniper rifle and the only time he will kill someone other than a male combatant. He states his conviction that he was correct to protect American lives, describing the enemy as a “savage, despicable evil” (4).

Kyle recounts his childhood in north-central Texas, where his father teaches him to hunt and shoot. In high school, he becomes a competitive rodeo cowboy, a career that ends after a severe injury leaves him with pins in his arm. He works as a ranch hand, developing patience while breaking horses. In 1996, a Navy recruiter inspires him to become a SEAL, but he is initially disqualified due to the pins. Two years later, the Navy reverses its decision.

In February 1999, Kyle begins his military career. He endures the grueling Basic Underwater Demolition/SEAL (BUD/S) training, graduating with Class 233 despite multiple injuries and other setbacks, and is assigned to SEAL Team 3. Kyle meets his future wife, Taya, in April 2001.

On the morning of September 11, 2001, Kyle is recalled to his base on standby for deployment. His platoon eventually deploys to the Persian Gulf in September 2002. They conduct maritime interdiction operations, boarding ships to enforce UN sanctions against Iraq, and work closely with the Polish Special Forces unit known as the “GROM.” On March 20, 2003, the Iraq War begins, and Kyle’s unit secures the al-Faw oil refinery after a chaotic landing and an intense firefight. Following this, they are assigned to a post on the Shatt al-Arab waterway which Kyle finds frustratingly inactive. They are briefly attached to the Marine advance near Nasiriya, but their commander’s casualty-averse strategy limits their involvement, again leaving Kyle deeply frustrated. The deployment ends, and Kyle returns home disillusioned with his leadership.

Back in the United States, Kyle attends and graduates from sniper school. During this time, Taya becomes pregnant, and their son is born through a difficult delivery.

In September 2004, Kyle deploys to Baghdad ahead of his platoon to work with the GROM, joining their direct action missions. When he is reassigned to the Second Battle of Fallujah, he and other SEAL snipers provide overwatch for Marine units. As the fighting moves deeper into the city, Kyle joins a Marine squad on the ground to lead room-clearing. During these operations, a collapsing wall from an RPG blast severely injures his knees, but he refuses evacuation. In this action, he earns a Bronze Star with Valor, for rescuing a group of trapped Marines. Kyle’s numerous kills during this time, including several at extreme distances, earn him the nickname “The Legend.” After Fallujah, he is sent to Baghdad for sniper overwatch on the perilous Haifa Street.

Between deployments, Kyle’s spends time at home, His marriage becomes strained when he voluntarily reenlists for redeployment, despite Taya’s objections. His second child, a daughter, is born days before he is scheduled to leave for his third tour. In April 2006, Kyle’s platoon deploys to Ramadi, considered the most dangerous city in Iraq for American troops. The platoon engages in intense firefights while establishing combat outposts. Kyle’s kill count rises, and insurgents place a bounty on his head, calling him al-Shaitan Ramadi (“The Devil of Ramadi”). Kyle’s teammate Ryan “Biggles” Job is shot in the face and permanently blinded and another teammate, Marc Lee, is killed, the first SEAL to die in Iraq.

Kyle returns home early from his third deployment after learning his infant daughter is critically ill. He attends the funeral of fellow SEAL Mike Monsoor, also killed in Ramadi. He undergoes surgery on both knees, followed by a grueling rehabilitation. His marriage reaches a crisis point, and he and Taya begin counseling. He agrees not to reenlist when the time comes.

For his fourth and final deployment in 2008, Kyle is assigned as lead petty officer of a new platoon. After he is transferred to a special task unit for the Army’s push into Sadr City in Baghdad, his unit is ambushed; two bullets are deflected by his armor, forcing him to confront his own mortality. Kyle provides sniper overwatch as the Army builds defenses, engaging in daily firefights. He is promoted to chief petty officer, but the accumulated stress of four combat tours causes his blood pressure to spike. He is sent home early, feeling as though he is abandoning his men.

Kyle leaves the Navy in 2009 and moves with his family to Texas. He struggles to transition into civilian life, falling into a depression and drinking heavily until he totals his truck while driving drunk. This serves as a wake-up call and Kyle co-founds Craft International, a tactical training company, and dedicates himself to helping wounded veterans. In 2010, Kyle’s friend Ryan Job dies from complications during a surgery related to his war injuries. Kyle reflects on his new life, finding purpose as a husband and father. He concludes that he has a clear conscience about his actions in war, believing every person he killed was “evil.” His only regrets are for the American lives he could not save.
