I know that the RAF and RNAS bods get an annual allowance to buy job-related training, more or less of their choice, and I imagine that the Army gets that too. It's not much (<£200 per year?), but every little helps. The unit education people should know about it, and if not you should rattle their cage a little.
Others on this thread will probably know more about this.
You've got 9-12 years to get fitted up with qualifications (EASA Pt 66 B1 or B2 all modules passed?) for when you leave after having had the best time of your life. Keep dodging the incoming.
If the Government - may their mistresses be infected - decide that you would benefit from early redundancy you won't regret doing it now.
Aaaaaahhhhh..............those were the days...
