The right voluntarily to associate together as a military company or organization or to drill or parade with arms, without, and independent of, an act of Congress or law of the State authorizing the same, is not an attribute of national citizenship. Military organization and military drill and parade under arms are subjects especially under the control of the government of every country. They cannot be claimed as a right independent of law. Under our political system they are subject to the regulation and control of the State and Federal governments, acting in due regard to their respective prerogatives and powers. The Constitution and laws of the United States will be searched in vain for any support to the view that these rights are privileges and immunities of citizens of the United States independent of some specific legislation on the subject.
