I mean, if you look back to the framing of the constitution, the idea was that a bunch of citizen militias would be kept such that if the country needed defense, they would be able to respond. This was because the new United States lacked (and politically opposed) standing armies like the one which they just fought off the continent.
Since then, the United States acquired an Army, Navy, and Air Force alongside numerous National Guard units. The theoretical need for citizen militias vanished.
The real answer to your question is that we really don’t have citizens participating in “well-regulated militias.” Not from the constitutional context, anyway.
