Article I (powers of congress)

To provide for calling forth the Militia to execute the Laws of the Union, suppress Insurrections and repel Invasions;

To provide for organizing, arming, and disciplining, the Militia, and for governing such Part of them as may be employed in the Service of the United States, reserving to the States respectively, the Appointment of the Officers, and the Authority of training the Militia according to the discipline prescribed by Congress;

Article II (president)
The President shall be Commander in Chief of the Army and Navy of the United States, and of the Militia of the several States

Clearly the framers intended "the militia" to be an organized, federally funded, federally commanded, organized body, not just any able bodied male capable of fighting and not any yahoo with an AR and camo playing games in the woods.
