Clint Van Winkle said this quote

I missed the war and the freedom that came with it. When you are that close to death, you feel free. Every breath you take could be your last. So you inhale and savor each breath, try not to think about your death even though signs of it are all around you. The freedom comes from knowing that if anybody gives you crap, you can eliminate them and the situation. Just shoot and get it over with.
