I believe this is a common sense proposition. You should never define a military force without it having a purpose.
You would think that there would be nobody on the other side of this question. Who would do such a crazy thing as to define a military force, but just have them milling around without a purpose or a mission? It’s ridiculous. Or is it?
(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.
What is the purpose of the military force called the unorganized militia? What is their mission? What is its proper scope of activity? I think that even people who generally support the 2nd amendment do not have a consensus and certainly have not thought much about it.
As an aside, it’s straight up sexism for female citizens to be included in only one of these two forces. A smart Republican would introduce legislation to fix that.
