War
War is a state of armed conflict between states or societies. It is generally characterized by extreme aggression, destruction, and mortality, using regular or irregular military forces. Warfare refers to the common activities and characteristics of types of war, or of wars in general. Total war is warfare that is not restricted to purely legitimate military targets, and can result in massive civilian or other non-combatant suffering and casualties.
War Studies
War studies, sometimes called polemology, is the multi-disciplinary study of war. The word derives from Ancient Greek πόλεμος (pólemos, "war") + -logy".
