In answer to your question - yes they do have their own FC brevet - and to those who may mock - after quite a hard 6-ish month OCU on 23 Sqn.
However the real issue is - I hope you're not planning on getting on E3s any time soon?
As someone that escaped the FC assylum a couple of years ago, I can see a re-run of the situation I was in late90s/early00s - lots of Navs / AEOs in desk jobs but still getting flying pay, so they stuck them down the back of the jet to make them earn their pay.
At a stroke 25% of the surveillance team slots went to rear-seaters overnight. Result lots of unhappy FCs stuck down the east coast waiting for the Ruskies. Can see the same thing happening with the current "re-organisation" when we end up with more aircrews than we can use.
But if that's what you're after, good luck mate, it aint a bad job. Oh and the currys you get on there are pretty decent too!
