Kyle returns home to his wife and the birth of his son. He is distracted by memories of his war experiences and by Taya’s concern for them as a couple – she wishes he would focus on his home and family. Kyle leaves for a second tour and is promoted to chief petty officer. Involved in a shootout with The Butcher, he helps in killing him. When he returns home to a newborn daughter, Kyle becomes increasingly distant from his family. On Kyle’s third tour, Mustafa seriously injures a unit member, Ryan “Biggles” Job, and the unit is evacuated back to base. When they decide to return to the field and continue the mission, another SEAL, Marc Lee, is killed by gunfire. Guilt compels Kyle to undertake a fourth tour, and Taya tells him she may not be there when he returns. Back in Iraq, Kyle is shocked to learn Biggles died in surgery to repair the wounds he sustained. Assigned to kill Mustafa, who has been sniping U.S. Army combat engineers building a barricade, Kyle’s sniper team is placed on a rooftop inside enemy territory. Kyle spots Mustafa and takes him out with a risky long distance shot at 2,100 yards (1,920 m), but this exposes his team’s position to numerous armed insurgents. In the midst of the gunfight, and low on ammunition, Kyle tearfully calls Taya and tells her he is ready to come home.
