Which of the following is a passive air defense measure?
Correct Answer:
Camouflage
Explanation:
Camouflage is a passive air defense measure because it reduces the defender’s visibility without relying on active systems or responses. By blending assets with the surrounding environment—through color, texture, patterns, and concealment techniques—it makes aircraft, vehicles, or facilities harder to detect and identify, lowering the chance of being targeted in the first place. This contrasts with detections or sensors that actively seek out threats, or with measures like hardening, which strengthen structures to resist damage, or dispersion, which spreads assets to reduce the impact of a strike—both of which rely on different kinds of active or structural defenses. Camouflage achieves protection simply by making assets harder to see, fitting the idea of passive defense.
