Don't get me wrong, I do not disagree with the sentiment of your main argument; it just isn't going to happen.
There probably were differences between the 3 Services in the rate of uptake of AFPS 05, and I don't know what they were, but I can assure you that it was by no means an easy and obvious choice for the majority of RAF personnel. The fact that across the 3 services as a whole, the voluntary transfer rate was limited to about 8% should tell us something about how wonderfully tempting the offer was for the majority of people!
