Seen as the airforce has allowed Cpls (in certain trades) to sign on past 22 for 3 more years, what's the thinking out there a good idea keeping experience in or is it holding back the youngsters, with the envitable knock-on with promotion? Which may well have started, SAC atm to cpl 41 out of 1900. Me I think they could lose as many as they keep in, if enough sac's leave if their career isn't going any where.
