GAD: There is a difference between being a member of A Militia, and being a member of THE Militia. See, the Militia Act, and Common Law at that time, defined every ablebodied gunowner as being in THE Militia. In other words, if the Redcoats cme, you were supposed to assemble & go out a shoot a few (which did happen, and was the main source of our earliest “victories”). But, if you were a member of A Militia, ie had a uniform, was drilled, had a standard calibre. etc, you were a much more valuable asset. So, yes, in a way the Militia Act was enacted to encourage men(THE Militia) to belong to A Milita, as it pointed out you had to show up & fight anyway, so you might as well have a snappy uniform. Remember, that the Feds had no real army, and there was nothing like the National Guard (once, perhaps A Militia, but now just a part of the Federal Armed Services). There were State, City and civic org Militias, ( imagine the local Mason Lodge having a small unit. During the early years of most Fraternal orgs, they WERE Militias, some of the remnants like swords continue to this day). Also there were PRIVATE Militias, where some rich landowner would provide uniforms for all his buddies & employeees so he could be a Captain or major, or something.
And we laff at the idea of “THE Militia” being of any use in modern warfare, but it is not as funny as you think. During WWII, the Japanese navy considered landing small groups of naval commandoes, who would place charges & blow up things like oil refineries. They correctly figured that our Military organization here on the West coast was disorganized & inadequate. However, early on, it was pointed out that just gun-totin americans could defeat such a force (I can just imagine the vision that went on the the High Commands mind, primed by years of gangster & western movies-- of men in 10 gallon hats & six shooters, side-by-side with dudes in pinstriped suits & tommyguns, sniping away at their valient but outnumbered landing party
). The sad thing was, that such a plan might well have succeeded, if there had been ONLY the Us Army to protect us. (Ever see “1941”?)
Is it not possible that the same thought crossed the mind of some terrorist groups, even recently?
So, yes, the 2nd applied to THE Militia, which = the Armed Public, but also they wanted more of THE Militia to get into A militia. We no longer have (any) "A militia"s (to speak of, there are a few still around, mostly as a way to give out honorary Colonelships), but we still have “THE Militia”. To this day, any sheriff can deputize you into the “posse”, a hangover, fromt he old days of militias.
