I don't have to psych myself up, or do something special mentally - I look through the scope, get my target in the cross hairs, and kill my enemy, before he kills one of my people.

Every person I killed I strongly believe that they were bad. When I do go face God there is going to be lots of things I will have to account for but killing any of those people is not one of them.

I did want to be the top sniper.

Savage, despicable evil. That's what we were fighting in Iraq. That's why a lot of people, myself included, called the enemy 'savages.' There really was no other way to describe what we encountered there.

It was my duty to shoot the enemy, and I don't regret it. My regrets are for the people I couldn't save: Marines, soldiers, buddies. I'm not naive, and I don't romanticize war. The worst moments of my life have come as a SEAL. But I can stand before God with a clear conscience about doing my job.

The Navy credits me with more kills as a sniper than any other American service member, past or present.

You have to slow your heart rate, stay calm. You have to shoot in between your heartbeats.
