Re: "the meaning of a well regulated militia"

In the 1700’s when the Second Amendment was written, well regulated didn’t mean government control - it meant “to make regular” or “be in good working order” which in today’s military parlance is often referred to as maintaining good order and discipline. See http://constitution.org/cons/wellregu.htm

According to current US law, there are 2 types of militias - organized and unorganized. The National Guard is part of the organized militia and everyone who is not in the organized militia is in the unorganized militia  - 

See 10 USC 311 at https://www.gpo.gov/fdsys/pkg/USCODE-2011-title10/pdf/USCODE-2011-title10-subtitleA-partI-chap13-sec311.pdf
