Aircrew Brevet
In the early eighties SAC Brian H****n was in ATC at Manston, wearing an ALM brevet.
He had done the 6 months on the Sqn that were required to earn the brevet but was subsequently remustered out of the trade.
They changed the rules pretty quickly after that and you had to attain "combat ready" status on a Sqn to qualify.
