That's really sad. I didn't read that he had one good eye yet. I hope so. I'm blind in one eye and it isn't the reason I'm not a great photog. It sounds like the soldier has a gift for photography. Even better it sounds like he has a passion for it.
Maybe we should find out if he has a good eye left and put our money where our heart is and pull together for a nice LF (or????) camera for him.
