The ATC is run by an RAF Air Cdre who is AOC Air Cadets. He has a small HQ staffed by uniformed reservists . These guys are full time ATC admin. This then works down to Regions, each with a uniformed, but retired (therefore also reservist) Group Capt. He and his small admin staff look after the Wings which have a VR(T) Wg Cdr and a J class reservist Sqn Ldr and a couple of civi staff. The rest of the Wing staff are VR(T) as are the Sqn staff, assisted of course by Civi Instructors (CI's) At Sqn and Wing level (maybe above that, but not sure of my facts on this bit) are Civi committees, run generally but not always so by parents of the cadets. No civi committee means the Sqn has to close, so these are important groups. They raise the funds that all ATC Sqns need, but which fall outside the RAF input.
In this half sevice, half civilian organisation, the work gets done, and very efficiently too. Why therefore is it considered a problem to make it all civilian, with a sudo military rank structure. There are pleanty of civilians running the RAF these days (SERCO etc) so why will it be a problem if the VR(T) loose their commissioned status?
