Which component is NOT part of the sustainment system?

The sustainment system encompasses various components essential for maintaining operational readiness and supporting forces in the field. Among these components are health service support, logistics, and personnel services, each playing a critical role in ensuring that soldiers are supplied with the necessary resources, equipment, and services needed for effective operations.

When considering strategic airlift capabilities, it is important to note that while they are vital for transporting personnel and supplies, they fall under the broader category of transportation rather than being a direct component of the sustainment system itself. The sustainment system focuses primarily on supply chain management, logistics, health services, and personnel support. Thus, strategic airlift capabilities are tools or methods used within the framework of sustainment but do not constitute a component of the sustainment system on their own.

This distinction clarifies why strategic airlift capabilities do not belong to the essential components that make up the sustainment system, setting them apart from the others listed.
