What should be planned according to the Extended OP Emplacement guidelines?

The correct answer is the planning of evacuation routes according to the Extended OP Emplacement guidelines. This is crucial because evacuation routes ensure that personnel can effectively and safely withdraw from an area when necessary, particularly in high-risk situations. The Extended OP Emplacement guidelines emphasize the importance of preparing for unforeseen circumstances, including the need to maneuver or retreat due to enemy engagement or other threats.

In the context of a Cavalry Scout's operations, understanding where to go and how to get there during an evacuation can greatly enhance survivability and operational effectiveness. While the other options—close combat strategies, weapon positions, and intelligence assets—are important components of overall operational planning, the focus of the Extended OP Emplacement guidelines specifically highlights the need for well-planned evacuation routes to maintain safety and operational integrity.
