During the air war of 1944, a four-man combat crew on a B-17 bomber took a vow to never abandon one another no matter how desperate the situation. The aircraft was hit by flak during a mission and went into a terminal dive, and the pilot ordered everyone to bail out. The top turret gunner obeyed the order, but the ball turret gunner discovered that a piece of flak had jammed his turret and he could not get out. The other three men in his pact could have bailed out with the parachutes, but they stayed with him until the plan hit the ground and exploded. They all died.

I don't think people would climb mountains or jump off bridges with parachutes or kayak Class V rapids if those things didn't offer the brief and horrible illusion of imminent death. They would just be complicated, time-consuming endeavors that we'd steer well clear of because they got in the way of real life.

The negative effects of combat were nightmares, and I'd get jumpy around certain noises and stuff, but you'd have that after a car accident or a bad divorce. Life's filled with trauma. You don't need to go to war to find it it's going to find you. We all deal with it, and the effects go away after awhile. At least they did for me.

The only thing that makes battle psychologically tolerable is the brotherhood among soldiers. You need each other to get by.

My wife, Daniela, and I live in an old house from 1810 with three fireplaces at the end of a dead-end dirt road on Cape Cod, so I turn the trees into firewood for us and a friend of mine sells the rest.

Combat isn't where you might die -- though that does happen -- it's where you find out whether you get to keep on living. Don't underestimate the power of that revelation. Don't underestimate the things young men will wager in order to play that game one more time.

Firemen don't talk about whether a burning warehouse is worth saving.
