"The Navy credits me with more kills as a sniper than any other American service member, past or present. I guess that's true," Kyle said of his sniper career. "They go back and forth on what the number is. One week, it's 160 (the 'official' number as of this writing, for what that's worth), then it's way higher, then it's somewhere in between. If you want a number, ask the Navy—you may even get the truth if you catch them on the right day."
