Which of the following is a type of security operation?

• A. Guard
• B. Screen
• C. Area Security
• D. Cover

Answer: (C)

Protecting a defined area—keeping that area secure against enemy access, infiltration, and threats—illustrates a security operation focused on the area itself. This involves establishing a security perimeter, manning observation posts, controlling entry points, and patrolling to detect and deter threats so the rest of the mission can proceed safely. The other options describe different security roles: guarding protects a specific person or asset; screening provides early warning of enemy movement ahead of the main force; and covering secures the main force by providing protection as it moves to or from an objective. Area security fits as the type of security operation that concentrates on the safety and integrity of the area.
