The original plan for WSOs was that it was for FJ navs only. It was going to be a 2 winged brevet for FJ backseaters. Then other VSOs got involved and looked to make a single brevet for all rear crew - although at that point commisioned WSOs were to get a crown on their brevets and WO/SNCOs would not get the crown. It's all a bit of a "dog's dinner" now IMHO and we would be better adopting the RAAF system of Air Combat Officers (ACOs):
Air Combat Officer - Defence Jobs Australia
They have quite a nice looking brevet as well that could compliment the recent introduction of the RPAS pilot brevet in the RAF:
Or maybe just go to 3 brevets for the RAF (which would save money in the supply chain):
Pilot
RPAS Pilot and Rear Crew:
VGS Gliding Pilot:
Or get rid of the gliding badge and just go for the 2...
Anyway, looking forward to the 'incoming'...
