I'm a better husband and father than I was a killer.

I really don't care what people think of me. I've got my family. I've got my friends. Yes, I have been trained to be a little more aggressive if I need to be, but I don't go around thumping people.

People tell me I saved hundreds and hundreds of people. But I have to tell you: it’s not the people you saved that you remember. It’s the ones you couldn’t save. Those are the ones you talk about. Those are the faces and situations that stay with you forever.

In the end, my story, in Iraq and afterward, is about more than just killing people or even fighting for my country. It's about being a man. And it's about love as well as hate.

I'm trying to raise the awareness of the troops that, when they deploy and go to war, it's not just them at war - it's also their family. Their family is having to go through all the hardships and the stresses.

Maybe war isn’t really fun, but I certainly was enjoying it.

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