Did I say that? I take it back.

If I at any time wrote that the National Guard is a militia within the meaning of the Second Amendment I take it back.

A militia is an organization of persons, civilians or not, keeping weapons of their own in their homes who can participate together in military training or actions using their own weapons as well as others maintained by the organization.

Just because they don't use their own weapons in their training or actual service, nor need they even own weapons, neither NGs nor Reservists are militia per se.

Of course, individual NGs and individual Reservists may also "on their own time" belong to a militia.

And, anyway, the amendment does not guarantee the right of the organization to own and bear weapons, but of the people in general (not only militia members), each as an individual.

Update, 6/29/2020.

Perhaps one reason it is so widely maintained that the NGs are indeed militia is that the constitution expressly allows the states to have and train militias but forbids them to have their own troops in peacetime.

So it cannot be admitted that the NGs are actually troops and not militia.

Tada.
