Military
A military or armed force is a professional organization formally authorized by a sovereign state to use lethal or deadly force and weapons to support the interests of the state and some or all of its citizens. It typically consists of branches such as an Army, Navy, Air Force, and in certain countries the Marines and Coast Guard. The task of the military is usually defined as defence of the state, and its citizens, and the prosecution of war against another state. The military may also have additional sanctioned and non-sanctioned functions within a society, including, the promotion of a political agenda, protecting corporate economic interests, internal population control, construction, emergency services, social ceremonies, and guarding important areas. The military may also function as a discrete subculture within a larger civil society, through the development of separate infrastructures, which may include housing, schools, utilities, logistics, health and medical, law, food production, finance and banking.

But now, instead of discussion and argument, brute force rises up to the rescue of discomfited error, and crushes truth and right into the dust. "Might makes right," and hoary folly totters on in her mad career escorted by armies and navies.
