Leadership is both a research area and a practical skill encompassing the ability of an individual or organization to "lead" or guide other individuals, teams, or entire organizations. Specialist literature debates various viewpoints, contrasting Eastern and Western approaches to leadership, and also (within the West) United States versus European approaches. U.S. academic environments define leadership as "a process of social influence in which a person can enlist the aid and support of others in the accomplishment of a common task". Leadership seen from a European and non-academic perspective encompasses a view of a leader who can be moved not only by communitarian goals but also by the search for personal power.
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.
Nay, number itself in armies importeth not much, where the people is of weak courage; for, as Virgil saith, "It never troubles the wolf how many the sheep be."
Francis Bacon, "Of the True Greatness of Kingdoms and Estates," The Essays or Counsels Civil & Moral of Francis Bacon, p. 129 (1905). Bacon quoted the words of Thyrsis in Virgil's Eclogue VII.
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.
