Which of the following is NOT a purpose of Area Security?

• A. To preserve the CDRs freedom of maneuver
• B. To move reserves
• C. Conduct sustainment operations
• D. To prevent direct fires against the main body

Answer: (D)

Area security is about protecting a defined area so the unit can operate there with minimal disruption, while maintaining the ability to observe, deter, and respond to threats. It focuses on securing the area’s boundaries, providing early warning of enemy movement, and ensuring routes for movement and sustainment remain open and uncontested.

Because of that, area security directly supports keeping the main body’s freedom of maneuver, and it enables the orderly flow of reserves and sustainment by protecting lines of communication and areas where supplies and reinforcements move. These aspects—preserving maneuver space, moving reserves safely, and conducting sustainment operations within a protected area—fit squarely with the purpose of area security.

Preventing direct fires against the main body is not the primary aim of area security. Guarding against direct fires belongs more to defensive actions and protective measures at the unit level. Area security provides security and observation to keep operations working smoothly, not the direct-fire defense of the main body.
