Thanks for all the replies.
I'm mainly focused on Nats however i had considered the others too.
' you would primarily be military personnel and 'secondary duties' would occupy a lot of your time'- Yeah I'm just really interested in the ATC aspect. Also, there is general military training before you even commence your ATC training which adds to the length of training.
'but it is not an easy application for any of your wants. good luck though'- I want a challenging career and if i do fail i have a backup anyway.
'you'll end up working at either Yeovs, Culdrose or Swanwick'- So the RAF grass is definitely greener.
