The "common" Militia was first established by the various colonies of all able-bodied men between roughly the ages of 16 and 60 for protection against Indian attack. These militiamen were required by law to be enrolled in the unit of their township or county, furnish their own arms and equipment, and appear periodically for training. They were civilian soldiers who had little or no taste for things military, as their performance in both peace and war almost invariably demonstrated. They were not uniformed and contributed little or nothing to the field of military dress. The "volunteer" or "independent" Militia companies, on the other hand, were something else again. These units, composed of men who enjoyed military life, or rather certain aspects of it, appeared rather early in the Nation's history. The first of these, formed in 1638, was The Military Company of the Massachusetts, later and better known as the Ancient and Honorable Artillery Company of Massachusetts. By 1750 there were a number of independent companies in existence--many of them chartered--and membership in them had become a recognized part of the social life of the larger urban centers. The concept of volunteer Militia units was confirmed in the Uniform Militia Act of 1792, which prescribed flank companies of grenadiers, light infantry, or riflemen for the "common" Militia battalions and a company of artillery and a troop of horse for each division, to be formed of volunteers from the Militia at large and to be uniformed and equipped at the individual volunteer's expense. Thus, from within the national Militia structure emerged an elite corps of amateur--as opposed to civilian--soldiers who enjoyed military exercise, and the pomp and circumstance accompanying it, and who were willing to sacrifice both the time and the money necessary to enjoy it. Since the members were volunteers, they were ready to submit to discipline up to a point; they trained rather frequently; many of the officers made an effort to educate themselves militarily; they chose their own officers; and their relative permanency gave rise to an excellent esprit de corps. In actuality, these organizations became private military clubs, and differed from other male social and fraternal groups only in externals.
