I think that being in an intense firefight and then less than 24 later, you are home in your bed, might be nice for the family, but it has to play merry Hell with the mind

Never was in combat, we were not allowed officially to be armed or shoot back.

But after having been on edge for 18 months you can not just come back home and sleep in your own bed without some sort of rest period. You have tuned yourself so tight for the sake of survival that you see danger everywhere. It is not paranoia, there was danger everywhere.

Now there isn't but it takes a while for that switch to flip (mostly) to the off position.

And if you are trying to do that around people that don't understand it is difficult.
