What are the three critical missions of the two trailing troops in a moving flank guard?

The three critical missions of the two trailing troops in a moving flank guard involve reconnaissance and the establishment of positions that are vital for maintaining situational awareness and control of the battlefield.

When focusing on reconnaissance, the first task—Recon BP's (Reconnaissance of Battle Positions)—is to gather information about terrain and enemy positions in the area of operations. This intelligence is essential for informed decision-making and ensuring that the main force can maneuver safely.

The second task, Occupy BP's (Occupy Battle Positions), involves moving into predetermined positions that provide a tactical advantage. This ensures that the troops are well placed to respond to any enemy action and to protect the flanks of the main body.

The third task, Occupy OP's (Occupy Observation Posts), is crucial for maintaining oversight of the surrounding area. Observation posts allow troops to detect enemy movements and assess potential threats, which is essential for the overall effectiveness of the flank guard.

These missions directly support the overall goal of a flank guard, which is to protect the movement of the main force by ensuring they are aware of potential enemy activity and can react appropriately.
