This is mind, perhaps the best way to rubbish Collins' chat is to ask him which major nation currently gets by with only a navy and an army?
This is the same as the recurring "all aircrew should be NCOs" and "we should just have one service" comments. I don't believe we'll do anything as extreme as that until the French, Americans, Russians, Candadians, Germans, etc etc all decide to do similar.
