Is the National Guard similar to the army reserve in Australia? I.e. a part time volunteer army primarily used for domestic humanitarian operations? Because if that's the case, it wouldn't seem like much effort for NG members to just quit. I know quite a few reserve members who have quit after seeing the military deployed in Sydney.
