He opts out of
the war on his second wound,

As I recall, Chris was wounded three times, and so was the one black soldier
who stabbed himself in the thigh after the big attack.

It's a minor distinction, you could be right, the point is more about opting out,
rather than the number of wounds. I believe the black soldier was more interested
in getting a blow job from the white nurses than anything else in life.
