I have good mates who are RPAS operators and from talking to them it just sounds like a really weird job and one that I certainly wouldn't like to do.
I wonder if the extra layer of stress/strangeness comes from knowing that you, the operator, are under absolutely no personal risk at all? Almost every other form of military combat comes with that element of personal risk but as an RPAS operator there is no kill-or-be-killed. Just the distant dispassionate dispatching of the enemy.
No matter what all you cold-steel-it-were-tuff-in-the-army-in-my-day might say, this is a whole new realm of warfare and if you employ intelligent and thoughtful people to do it then they're probably going to think about it intelligently. I know I'd struggle with a job that involved me killing people and where the only personal risk I faced was the possibility of an an RTA on the 95.....
