Adam, whilst Tourist's post is him taking a bit of a cheap shot- first of many- I agree with the first bit. The RAF is much less 'left right, left right' than the army. You'll be very unlucky (or very naughty, and caught) to spend much 'marching' time after training. If you fly helicopters, you will have lots more green possessions that your jet chums, but even they are now tested to see if they do indeed recognise the colour.
