I am ex Royal Air Force. HM Forces are by far the best training institutions in the world. You get all the training you need and want for free, its full time, you get fed and watered, and best of all they pay you well for doing it.
I was trained as an Aircraft Electrical Mechanic, and further trained to Technician. I also did ONC Electrical engineering at local college. Then I got The JAR 66 B2 Aircraft Maintenance Licence again at their expense, in todays money that would cost about £20,000.
With training and further training, the potential is limitless, it is up to you how far you want to go.
When you get into your last couple of years service before leaving the forces you will be able to go on resettlement courses, again these are free and are of your choosing to suit your preferred choice of career once you are discharged, so if you went down the sparky route then thing like PAt testing, 2391, 17th edition etc etc would be available, i did domestic appliances amongst other things, not only that but you can also start a new job up to about 11 weeks before you are out because you get 6 weeks resettlement leave and about 7 weeks annual leave.
Things will have changed since i came out 20 odd years ago, but my brother is still serving as a Squadron Leader supply officer in Khandahar, he is due out in May 2011, he will be 40, full pension and massive lump sum, he is taking a PGA qualification to become a Golf Pro and The RAF are picking up the tab, nice.
Your forces qualifications will be exactly the same as the civilian ones, but your employability will be far superior. For the first 5 years after my discharge i got offered every job i applied for.
Good luck and let us know how things go in the future.
Cheers..........Howard
