Do we have them? Because Voldemort's seemed pretty chaotic, if you ask me. Is there any references to wizards actually making armies like the US and British ones? And if they did, would they be Ministry/Government commanded?

And sorry to be a real pain, but say they were Ministry commanded. Would there be rules on when you could leave and who could join and all that? And would the ranks be the same as Muggle armies?

Thank you!
