Federal law gives us an Organized and an Unorganized militia. The Organized militia is the male members of the National Guard, and the Naval militia, while the Unorganized militia is the female members of the National Guard and all 17-45 year old able bodied males. If we adjust for equality, we are back to pretty much the definition that Madison used, the whole body of the people. Also, well regulated does not have to mean so much as trained, but familiar with the use of their weapons. I used to have a well regulated watch. It was not trained.
