Combat or fighting is a purposeful violent conflict meant to weaken, establish dominance over, or kill the opposition, or to drive the opposition away from a location where it is not wanted or needed.
The term combat (French for fight) typically refers to armed conflict between opposing military forces in warfare, whereas the more general term "fighting" can refer to any physical or verbal conflict between individuals or nations. Combat violence can be unilateral, whereas fighting implies at least a defensive reaction. A large-scale fight is known as a battle. A verbal fight is commonly known as an argument. Combat effectiveness, in the strategic field, requires combat readiness. In military areas, the term is applied also to personnel, that has to receive proper training and be qualified to carry out combat operations in the unit to which they are assigned.
