Kyle meets Taya Studebaker at a bar, and the two soon marry. He is sent to Iraq after the September 11 attacks. His first kills are a woman and boy who attacked U.S. Marines on patrol with a Russian made RKG-3 anti-tank grenade. Kyle is visibly upset by the experience, but later earns the nickname "Legend" for his many kills. Assigned to hunt for the al-Qaeda leader, Abu Musab al-Zarqawi, Kyle interrogates a family whose father offers to lead the SEALs to "The Butcher", al-Zarqawi's second-in-command. The plan goes awry when The Butcher captures the father and his son, killing them while Kyle is pinned down by a sniper. This sniper goes by the name Mustafa and is an Olympic Games medalist from Syria. Meanwhile, the insurgents issue a bounty on Kyle.
