Which of the following is NOT an Active rear area security measure?

• A. Camouflage
• B. Coordinating reconnaissance/surveillance
• C. Positioning air defense units in the rear
• D. Providing security to convoys

Answer: (A)

In rear area security, actions that directly detect, deter, deny, or respond to threats are considered active measures. Coordinating reconnaissance and surveillance is an active task because it involves planning and conducting monitoring to uncover enemy activity. Placing air defense units in the rear is an active defensive posture, creating fires to counter threats before they reach critical assets. Providing security to convoys is also active, as it involves protective measures, route security, and incident response to keep movement safe. Camouflage, on the other hand, is a concealment technique designed to reduce visibility and detection; it supports security indirectly but does not involve active protection, detection, or response. So camouflage is not an active rear area security measure.
