What purpose does a terrain model serve during combat orders?

A terrain model serves the critical purpose of visualizing the battlespace, which is essential during the planning and execution of combat orders. By providing a three-dimensional representation of the operational environment, a terrain model helps Marines better understand the geographical features, potential obstacles, and tactical advantages of the area in which they will operate. This visualization aids in effectively communicating the mission plan, allowing all members to grasp the layout of the terrain and their respective roles within it, ultimately leading to more informed decision-making and coordination during combat operations.

The other options do not adequately reflect the role a terrain model plays; it is not designed to distract Marines, compete with enemy forces, or create confusion, all of which would detract from the primary mission of clear communication and situational awareness.
