What are the GCM's for a moving flank guard?

The correct choice highlights critical components of a moving flank guard, which is essential for ensuring the security of the main body while conducting operations. In this context, dual purpose positions (PLs), battle positions (BPs), and engagement areas (EAs) are fundamental to effectively executing the mission of a flank guard.

Dual purpose positions allow the guard to respond to threats from both parallel and perpendicular angles, enhancing flexibility and responsiveness to enemy movements. This adaptability is crucial when managing potential encounters with adversaries who may be attempting to flank or exploit vulnerabilities in the formation.

Battle positions are designated areas where forces can prepare for combat, providing them with the necessary cover and strategic advantage to successfully engage the enemy while moving. Establishing well-defined BPs is vital for maintaining momentum as well as situational awareness.

Engagement areas define the spaces where forces anticipate and prepare to engage the enemy, ensuring that movement through the area is defended and that contact can be made under favorable conditions. By thoroughly planning these engagement areas, a moving flank guard can effectively manage threats that arise during the operation.

In conclusion, these elements are key to the effectiveness of a moving flank guard, allowing for the protection of the main body, maintaining combat readiness, and ensuring that forces can effectively respond
