What is the defense of a broad area called?

The defense of a broad area is referred to as area defense. This concept focuses on defending a larger geographical space rather than concentrating on a specific point. It involves coordinating resources and tactics to protect an entire region or territory, addressing potential threats that may emerge at various points throughout that area.

Area defense is essential for ensuring that forces can respond to multiple threats over a wide range. This strategy often encompasses the use of aerial, ground, and naval assets working together to provide comprehensive protection, making it effective against a variety of attack methods and dispersing the risk associated with point or sector defenses.

The other options, while relevant to defense strategies, focus on narrower scopes. Point defense targets specific locations, such as military bases or critical infrastructure. Zone defense would imply protecting specific zones or divisions within a broader area but does not encapsulate the substantial expanse that area defense covers. Sector defense would similarly concentrate on sections of a broader area rather than the holistic approach intended by area defense.
