What is included in Sustainment?

Sustainment encompasses a comprehensive range of activities that are essential for maintaining and supporting military operations. It integrates various aspects, with logistics and health services support being fundamental components. Logistics involves the planning and execution of moving troops, equipment, and supplies, while health services support ensures that personnel receive the necessary medical care to maintain operational effectiveness. This holistic approach is vital for sustaining the force in the field, enabling them to carry out their missions effectively.

The other options represent narrower aspects or incomplete concepts related to sustainment. The second option focuses solely on transportation, which is just one part of a much broader logistics function. The third option, while relevant to operations, does not directly pertain to the sustainment of troops. The fourth option limits the definition to only food and water provisions, neglecting the broader logistical and health service needs required for sustainment.
