 The Militia Clauses gave Congress authority for "organizing, arming, and disciplining" the militia, and "governing such Part of them as may be employed in the Service of the United States", with the States retaining authority to appoint officers and to impose the training specified by Congress.Proponents describe a key element in the concept of "militia" was that to be "genuine" it not be a "select militia", composed of an unrepresentative subset of the population.This was an argument presented in the ratification debates.
