Technically, divisions and allies are the same in this case. A lot of Wb's division commanders were part o f his main crew. But a good amount of them had their own crews. So, I think this will be the case with the strawhat pirates, Luffy being Luffy will never acknowledge it as such though lol. So far he multiple islands, and a few crews that will help him anytime he calls for it.
