What is the function of a Close Boundary Sentry (CBS)?

• A. Monitors interior perimeters with no exterior duties.
• B. Handles post manual security logs for the restricted area.
• C. Provides security surveillance over boundary of restricted areas.
• D. Operates crowd control during large events.

Answer: (C)

The core idea is that a Close Boundary Sentry is responsible for security surveillance along the outer boundary of a restricted area. This role focuses on detecting and deterring any intrusion attempts at the perimeter, maintaining perimeter integrity, and coordinating a rapid response when a breach or threat is observed. They watch for unauthorized approaches, tampering with fences or gates, and suspicious activity near the boundary, using sensors, cameras, and patrol information to maintain situational awareness.

This differs from monitoring interior perimeters, which would be a separate task tied to internal security zones rather than the outer edge. It also isn’t about administrative duties like logging post procedures, nor is it about crowd control at events, which involve different procedures and personnel.
