I'm not qualified or in posession of enough facts to make any kind of informed decision about this... and unless we have a few current serving Brigadiers/Commodores knocking about nobody else is, really....
However, I noticed above someone suggesting moving IOT to Raleigh? Frankly, that is a ridiculous idea, and is completely wrong. All initial officer training is not like initial recruit training, for any service simply because YO's need a bigger knowledge base. What ratings need to include strategic studies and defense writing in their militarisation phases? hmm? Do they need to get their European Driving License? Know Rule of the Road?
Same goes for any of the services, it just isn't possible or right.
Therefore, you need to differentiate between them, and Britannia has a history going back hundreds of years, and in the general scheme of things costs penuts to run. Looking in the wrong direction entirely old chap.
(Why all three services couldn't amalgamate the selection procedure - (AOSB/AIB/OASC) I don't know.
