In his book, American Sniper, Kyle describes his longest successful shot: in 2008, outside Sadr City, he killed an insurgent sniper aiming at other members of the US military with "a straight-up luck shot" from his McMillan Tac-338 sniper rifle from about 2,100 yards (1,920 m) away.
I sin bog "American Sniper" beskriver Kyle sit længste succesfulde skud nogensinde: i 2008, uden for Sadr City, dræbte han en oprører, som var i gang med at fyre en manuel panserværnsgranatkaster (RPG) af mod en amerikansk konvoj med et "heldigt skud" fra sin McMillan Tac-338 riffel fra en afstand af omkring 1920 meter.
