Military defense is the protection of a nation or territory against armed attack.
It encompasses forces, weapons, infrastructure, and strategy maintained to repel or deter aggression: The country allocated billions to military defense.
Defense can be reactive—responding to invasion—or preventive, through deterrence and fortification.
In government, defense often names the department or ministry overseeing armed forces: the Department of Defense, the Ministry of Defence.
