Armoured warfare or armored warfare, is the use of armoured fighting vehicles in modern warfare. It is a major component of modern methods of war. The premise of armoured warfare rests on the ability of troops to penetrate conventional defensive lines through use of manoeuvre by armoured units.

Modern warfare is warfare that diverges notably from previous military concepts, methods, and technology, emphasizing how combatants must modernize to preserve their battle worthiness. As such, it is an evolving subject, seen differently in different times and places. In its narrowest sense, it is merely a synonym for contemporary warfare.
