The RAF's chain of command only ever really extended up to unit and station level. Now it would seem it only goes as far as the former. Above that, as has already been pointed out, are merely varied levels of administration. Command means just that, the ability to get on a phone or drag into one's presence, bang heads together, and get things done. It is a fundamental requirement in a military organisation, the other side of the requirement to do one's duty to the point, if required, of paying the ultimate price. We all know that now as the Military Covenant, but long before it was just plain common sense. "Money, Mail, Meals", was an easier concept for JO's to grasp. Without that power of command, no matter how grand the title, "Air Officer Commanding-in-Chief" or whatever, he or she is not a commander. Not their fault simply fact, for you cannot expect to lead men and women to war without the ability to look after them when they or their loved ones need it. You might just as well hand it all over to Capita...oh, we already have? I didn't realise.
