Probably better to think in terms of a "military philosophy society" or something like that -- the idea isn't to build a logistics chain for conducting combat operations (that is what a militia has to do) but rather provide a pro-social context for people to learn skills and safety and military history. In the event of a conflict, the members of such an organisation would join the military, not deploy as a separate group with their own colours or what have you (which is what a militia would do).
