IOT at Cranwell may go elsewhere, but I'd be amazed if the station itself was closed. Let's face it, IOT can be done anywhere where there is a running track, somewhere to erect tripods and some classrooms. The training though is DIFFERENT for Navy, Air Force (and Army). I don't care how joint operations get, the operating varies between the services and not because we're trying to be different! We do need to know what the other chaps are doing, we don't need to be able to do their job for them.
Perhaps this is just so that senior orficers can refurbish CHOM and use it themselves because it looks nice
