The Queen basically serves as an extra head of state, a useful diplomatic figure and not much more. I don't think the UK monarchy is a net-negative but admittedly isn't all that necessary either. I come from a military town so my view may be different to some but I believe you need to be able to fight when you are threatened and to do that you need to be prepared. It's very hard to be prepared if you don't have a military and competent, motivated and well trained people to fight in it.
