You don't really need militias. If a majority of the people oppose the dictator and the military man are from these families then your coup is going to fail. That's why dictatorships with strong oppositions try to lure a portion of their population against another portion or hire an army from another country.
In a nutshell, the current US army is not going to attack their fellow citizens anytime soon for the eyes of a dictator.
That's the real (failed) purpose of the second amendment, to prevent the use of a professional armed force for internal and/or external security, with it's invariable separate subculture, so that the views of the masses of the people and those of the armed forces would not be distinct.
