What is the primary purpose of a fire support overlay?

The primary purpose of a fire support overlay is to graphically represent fire support measures and target areas. This tool is critical for operational planning as it visually communicates important information about where fire support will be directed, the locations of friendly forces, and any specific restrictions or considerations that need to be taken into account during operations. By providing a clear visual depiction, the overlay aids in coordination among units and ensures that all personnel involved in the operation have a common understanding of the fire support plan.

While other options may relate to aspects of fire support, they do not capture the essential role of the overlay in facilitating effective communication and operational planning. A budget for fire support operations or documentation of historical missions does not serve the immediate tactical need for coordination and situational awareness in planning. Similarly, training personnel on targeting procedures is a broader educational goal, whereas the overlay is a specific tool meant for the execution phase of military operations.
