Indeed pr00ne! Not just RAFAT, but even UASs have precious few QFIs these days, sadly.
There was enough 'fat' in the system pre-GW1 to spring some QFIs back to the front line after a couple of weeks of refresher flying, but with the advent of MFTS any flexibility has long since disappeared.
A surge in pilot training simply couldn't happen these days - there aren't enough aircraft, aerodromes, instructors or ground crew capable of coping with any large demand.
I read recently that the largest UAS was only capable of achieving 6 first solos, 2 first solo sector recces and 1 first aerobatic solo in an entire year......
