I heartily recommend the Career Transition Workshop briefings as well as the comments about writing the CV yourself.
I found the biggest problem with joining the real world again was selling myself to a potential employer, as we (ex-military) have lots of skills that are sought after in the civilian world, but it is often difficult to translate what we know and do into language that is understandable to an interviewer.
As it happens the first employer I approached for a job interview almost snapped my arm off trying to get me in the door and I'm happy to say that a much better wage, a fair few employee benefits (such as free private dental, healthcare and a great pension scheme) plus job flexibility make it a good job.
To be really honest I'm quite shocked at how much I don't miss the RAF. I thought I was going to struggle without my light blue comfort blanket.
