Chris Kyle was a US Navy SEAL sniper who did four tours of duty in Iraq, killing 255 enemies, 160 of them confirmed. Thus, he holds the record for the most confirmed kills in US military history, surpassing the earlier record of 109 kills established by Adelbert Waldron in Vietnam. Chris Kyle was born in Odessa, Texas, USA, to a Sunday school teacher and Deacon. When he was 8 years old, his father gave him bolt-action .30 Springfield rifle, which he used for hunting. In 1999, having worked as a professional rodeo rider, Kyle joined the US Navy. After a period of hard strenuous training, which included diving and parachuting, he became a US Navy SEAL and was asigned to SEAL Team 3, Sniper element, Charlie Platoon.
In Iraq, Kyle killed 40 insurgent Islamists in the Battle of Fallujah alone, seven of them through the window of an apartment building while lying on top of a baby crib he had turned upside-down. Then, near Sadr City, from a distance of 1.2 miles, he killed an insurgent, who had been aiming a rocket launcher at an approaching American convoy. Thus, with his .338 Lapua Magnum rifle, Kyle surgically removed the enemy threat, following strict rules of engagement, only targeting armed insurgents, in the process saving the lives of American soldiers.
