Which form of security would most likely be tasked with establishing a protective perimeter around a route or objective?

• A. Screen
• B. Cover
• C. Local
• D. Guard

Answer: (D)

Guard is the form that focuses on establishing and maintaining a protective perimeter around a route or objective. This role sets up checkpoints, positions sentries, conducts patrols, and controls who can enter or exit the area, creating a continuous security barrier that detects and deters threats. The other forms serve different functions: screening handles early warning and observation to support the main force, cover provides protective fire or concealment for movement or positions, and local security concentrates on security within a specific area rather than a route-wide perimeter. So establishing the perimeter and controlling access around the route or objective is the guard’s primary task.
