(a) The militia of the United States consists of all able-bodied males at least 17 years of age and, except as provided in section 313 of title 32, under 45 years of age who are, or who have made a declaration of intention to become, citizens of the United States and of female citizens of the United States who are members of the National Guard.
(b) The classes of the militia are—
(1) the organized militia, which consists of the National Guard and the Naval Militia; and
(2) the unorganized militia, which consists of the members of the militia who are not members of the National Guard or the Naval Militia.
So the militia still exists last amended in 1994. To this INAL anyway.
Also for those not as knowledgable any part of the constitution is valid until amended via the established process. Congress and the President can't change it unless the sovriegn (the people) do so.
So there is no snap your fingers to ignore it though the Supreme Court can establish how it is interpreted. Much like the fourth amendment has mostly gone away in way too many respects. Another topic.<shrug>
Wish there were easy answers in life but generally easy is either inconsequential or wrong.
Have fun,
