A well-armed citizenry a check against military tyranny

VOICES OF HISTORY, Alexander Hamilton, Federalist Papers No. 29

To oblige the great body of the yeomanry, and of the other classes of the citizens, to be under arms for the purposes of going through military exercises and evolutions, as often as might be necessary to acquire the degree of perfection which would entitle them to the character of a well-regulated militia, would be a real grievance to the people, and serious public inconvenience and loss. It would form an annual deduction from the productive labor of the country… to an amount which, calculating upon the present numbers of the people, would not fall far short of the whole expense of the civil establishments of all the States. To attempt a thing which would abridge the mass of labor and industry to so considerable an extent, would be unwise, and the experiment, if made, could not succeed, because it would not long be endured. 

Little more can reasonably be aimed at, with respect to the people at large, than to have them properly armed and equipped; and in order to see that this be not neglected, it will be necessary to assemble them once or twice in the course of a year.

This will not only lessen the call for military establishments, but if circumstances should at any time oblige the government to form an army of any magnitude that army can never be formidable to the liberties of the people while there is a large body of citizens, little, if at all, inferior to them in discipline and the use of arms, who stand ready to defend their own rights and those of their fellow citizens. 

This appears to me the only substitute that can be devised for a standing army, and the best possible security against it, if it should exist.

If there should be an army to be made use of as the engine of despotism, what need of the militia? If there should be no army, whither would the militia, irritated by being called upon to undertake a distant and hopeless expedition, for the purpose of riveting the chains of slavery upon a part of their countrymen, direct their course, but to the seat of the tyrants, who had meditated so foolish as well as so wicked a project, to crush them in their imagined intrenchments of power, and to make them an example of the just vengeance of an abused and incensed people? Is this the way in which usurpers stride to dominion over a numerous and enlightened nation? Do they begin by exciting the detestation of the very instruments of their intended usurpations? Do they usually commence their career by wanton and disgustful acts of power, calculated to answer no end, but to draw upon themselves universal hatred and execration? Are suppositions of this sort the sober admonitions of discerning patriots to a discerning people? Or are they the inflammatory ravings of incendiaries or distempered enthusiasts? If we were even to suppose the national rulers actuated by the most ungovernable ambition, it is impossible to believe that they would employ such preposterous means to accomplish their designs.
