Which is the sixth Air Defense Principle?

• A. Mobility
• B. Integration
• C. Agility
• D. Flexibility

Answer: (C)

Agility is the sixth Air Defense Principle because it focuses on rapid adaptation and execution in a dynamic battlespace. Threats can change in an instant—where they come from, how many there are, and what they’re using. To counter this, air defense forces must quickly adjust directions, reallocate sensors and shooters, reposition assets, and change engagement plans on the fly. Agile systems and teams keep the decision loop short, ensuring decisions are translated into action fast enough to preserve coverage and effectiveness as the situation evolves.

Mobility is about moving assets location-wise, which is important but doesn’t capture the speed and adaptability of decision-making and action. Integration deals with making sure different parts of the system work together, and flexibility is about being able to handle varied missions; both are essential, but agility specifically emphasizes how quickly you sense, decide, and act in response to changing threats.
