The whole thing seems very odd to me.
This bloke seems to be being stitched up like a kipper. Shouldn't someone point out to the RAF that if they 5hit on one of their controllers, then they can expect a significant proportion (Possibly so many that the system fails to operate) to leave the service.
I'm not a Mil ATCO, but if I was, I would happily leave any pension benefits behind me to have an employer who would back me up in times of trouble.
Whether that employer is NATS remains to be seen however....
Whoever you are, Good Luck.
