Ploddalong,
If you listen to the more reasoned responses, then you'll be okay. Those that have experienced both careers tend to be able to see the best (and worst) of both worlds. There are many good things about mil and civvy controlling careers - both provide a challenging and rewarding career. I've done both. I thoroughly enjoyed my career in the RAF and am happy to have joined NATS.
The great distinction is that, outside of your day-to-day controlling duties in the RAF (or RN

), much much more will be expected of you. As others have said before me: Officer first, controller second. I left the RAF, as I was destined to sit behind a desk for the rest of my career. As your career as an officer progresses (as I hope it would), you are less and less likely to be involved as a coal face controller. That does suit quite a few, but did not appeal to me.
Good luck to you in whatever career path you choose to follow.

Chevvron,
As for the FC branch doing AAR. If the performance of the FC at MPA in 2000 was anything to go by

, then not a lot of AAR would get done

. Mil area radar mates are pretty handy at it.
