The Marine Corps credited Mawhinney with 103 kills as well as 216 ‘probable’ kills that could not be confirmed because of the dangerous conditions in which the shootings happened…. The Oregon native recorded all of the kills before he turned 20….. Serving as a sniper “was the ultimate hunting trip: a man hunting another man who was hunting me,” Mawhinney told the Los Angeles Times in 2000. “Don’t talk to me about hunting lions or elephants; they don’t fight back with rifles and scopes. I just loved it.”
