Which statement correctly describes sustainment in prolonged operations?

• A. They are unnecessary if a mission is short
• B. Pre-positioned stocks, established supply lines, and flexible logistics plans support sustainment
• C. Sustainment is solely about food and water
• D. Maintenance of equipment is unrelated to sustainment

Answer: (B)

Sustainment in prolonged operations means keeping a force supplied and supported over time so they can continue the mission without interruption. It’s more than just food and water: it includes fuel, ammunition, medical support, maintenance and repair, spare parts, transportation, and services needed to keep people and equipment functioning.

Pre-positioned stocks at key locations, established supply lines, and flexible logistics plans are sustainment enablers because they shorten response times, ensure a steady flow of materiel, and let the operation adapt to changing conditions on the ground. That combination best describes how sustainment maintains operational capability over an extended period.

The other statements miss the full picture: sustainment isn’t unnecessary for short missions, it isn’t limited to food and water, and maintenance of equipment is a fundamental part of sustainment rather than being unrelated.
