Which component of sustainment planning ensures that supplies and materials can reach units over time in a combat operation?

• A. Maintenance
• B. Medical support
• C. Transportation
• D. Provisioning

Answer: (C)

The key idea is that sustainment hinges on moving resources to the fight. Transportation is the function that plans and executes the movement of supplies, equipment, and personnel from suppliers and depots to units in the field, choosing routes, modes, timing, and security to ensure deliveries arrive when needed. That ability to deliver materiel over time to the right place under combat conditions keeps operations flowing and avoids bottlenecks.

Provisioning focuses on stocking and ordering items, maintenance on keeping equipment functional, and medical support on patient care and casualty treatment. None of these alone guarantees the actual movement of goods to where they’re needed, which is what transportation provides.
