As someone else said "Read a book!" you have major misunderstandings of the "militia".
In the late 1700's "well regulated" meant skilled, trained and equipped, not controlled by regulations and rules. "Strangely" to understand what people of the past wrote you have to know the history of language and words and know what they meant when written, not what their modern meaning is.

And the "militia" was* all able bodied males of military age in good health. The Uniformed Militia was units of those individuals who joined together, trained and had uniforms and organization and were ready to be called to duty by the state or President when needed. Today that role is largely fulfilled by the National Guard though some areas still have militia units and some of them have been incorporated into the Guard. The Guard was officially created in the 1903 amendment to the Militia Act. The others are part of the Unorganized Militia. And you were required to have your own gear, weapon and ammunition when you reported. Many of those Uniformed Militia units had that provided by local government or a rich individual.

*Actually it is not "was", it is "is" the militia act in amended form is still a US law. It is just that no one bothers to enforce it in the strict sense any more.
Google "Militia Act" and you may find you are/were a member of the militia and didn't even know it.

PS: I did aprx 120 hours of grad level seminars on the Constitution and Bill of Rights - recruited by one of my professors at Cal State University LA and paid to attend by "The National Endowment for the Humanities" as part of a program for continuing education for classroom Social Studies teachers. And some of my fellow seminar members were surprised when they found not only what the Militia Act was but that it is still around and they or their family members were or had been militia members without knowing it.
