War is a phenomenon of organized violent conflict, typified by extreme aggression, societal disruption and adaptation, and high mortality. The objective of warfare differs in accord with a group's role in a conflict: The goals of offensive warfare are typically the submission, assimilation or destruction of another group, while the goals of defensive warfare are simply the repulsion of the offensive force and, often, survival itself. Relative to each other, combatants in warfare are called enemies.
