What type of support areas are represented in the sustainment overlay?

In a sustainment overlay, the representation of all support areas is crucial for effective large-scale combat operations. Such overlays are designed to provide a comprehensive view of the various logistical and medical resources required to support combat forces throughout the duration of an operation.

Including all support areas ensures that commanders have a complete understanding of the capabilities available for sustaining operations, from medical care for injured personnel to logistical supplies such as ammunition, food, and fuel. This holistic approach enables better planning and coordination, optimizing resource allocation and enhancing operational effectiveness.

By having a detailed overview that encompasses every aspect of sustainment, military leaders can make informed decisions about resource distribution, priority settings, and the overall logistical framework necessary to maintain combat readiness. Thus, the correct answer reflects this comprehensive nature of support areas within the sustainment overlay.
