How on earth do the other cadet forces cope with having WO ranks for their cadets when they all age out at 18? They develop their cadets - why don’t you Teflon?
Why do you need to keep CWO as an 18+only rank? I recently had a 17yo CWO and she would have beaten most 19 year old ATC CWOs I’ve met. Not because they are bad, but because she was great. In the ATC she would have had to wait a year to get the rank she deserved.
(Just to add for fairness I’ve seen some truly dreadful ones in the CCF as well, especially in schools where they promote to establishment rather than ability - i.e. the senior cadet must be a WO equivalent, senior in each service section must be a FS equivalent)
