militiaman

A militia generally is an army or other fighting unit that is composed of non-professional fighters, citizens of a nation or subjects of a state or government who can be called upon to enter a combat situation, as opposed to a professional force of regular, full-time military personnel, or historically, members of the fighting nobility class (e.g., knights or samurai). Unable to hold their own against properly-trained and -equipped professional forces, it is common for militias to engage in guerrilla warfare or defense instead of being used in open attacks and offensive actions.
