Except the part where there was NO militia when the amendment was conceived, written and passed.

The beginning of the United States military lies in local governments which created militias that enrolled nearly all free white men. The militia was not employed as a fighting force in major operations outside the local jurisdiction. Instead, the colony asked for (and paid) volunteers serving in ranger and other provincial troops (see above), many of whom were also militia members. The local Indian threat ended by 1725 in most places, after which the militia system was little used except for local ceremonial roles. The militia system was revived at the end of the colonial era, as the American Revolution approached; weapons were accumulated and intensive training began. The militia played a major fighting role in the Revolution, especially in expelling the British from Boston in 1776 and capturing the British invasion force at Saratoga in 1777. However most of the fighting was handled by the Continental Army, comprising regular soldiers.

Everyone, (well every male)

Not black men. Not “mulattos”. Not slaves. Which the funny thing is that gun regulations have been historically motivated by black folks getting guns - see how laws changed in response to the Panthers.

There’s a difference between a compulsory service in an organized regiment, where you presumably receive training on how to use said weapons, and “the founders wanted everyone to have the right to have anti aircraft rounds in their home.”
