How far back can a protecting force move in a Guard or Cover?

In the context of military operations involving a protecting force in a Guard or Cover role, the key aspect is understanding the tactical considerations regarding distance in relation to enemy capabilities. The correct answer focuses on the maximum range of the enemy's longest-range direct-fire weapon system, which is critical for maintaining safety and effectiveness in operations.

By moving back the same distance as the maximum range of the enemy's longest-range direct-fire weapon, a protecting force ensures that they remain out of immediate danger while still being in a position to fulfill their mission. This distance allows for proper reaction time and coordination with the main body, as well as an opportunity to observe and engage any threats.

In contrast, other options propose distances that do not fully account for the capabilities of the enemy. Limits like half the distance from the main body or twice the distance of usual deployments can expose the force to unnecessary risk if an enemy is capable of engaging them at longer ranges. Therefore, basing the movement distance on the enemy’s weapon system range is a strategic choice that prioritizes the safety of the protecting force while ensuring operational readiness.
