I was going to answer exactly the opposite. All real American adults are or have been in the militia, so the category excludes only Obama and the rest of his illegals:

10 U.S. Code § 311 - Militia: composition and classes
(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.
See my note re: if it is everyone then it is no one.
Now, we can REALLY have fun with “paramilitary.” :)
