My Dad served in the Korean WAR. He saw a lot of combat and was on the 38th. One day (while we was out) his tent got shredded by shrapnel. I still remember him waking up in the night once in a while yelling. AND he was VERY "gun shy". You didn't want to walk up behind him and startle him. He decked more than one person over the years.

I thank him all the time.
