Sustainment ensures continued ________ of operations.

• A. Morale
• B. Support
• C. Supply
• D. Readiness

Answer: (B)

Sustainment in operations is about keeping forces supplied and enabled to keep fighting, through ongoing logistics and services. Its primary purpose is to provide the ongoing support that lets operations continue without interruption. This includes provisioning, maintenance, transportation, medical care, and administrative services—everything that keeps the force capable over time.

That’s why the best fit is "support." Sustainment exists to ensure continuous support for operations, enabling missions to proceed even as conditions change. Morale, while important, is not the direct, sustained provisioning aspect. Supply is a major component of sustainment, but sustainment covers more than just supplying goods. Readiness is the outcome that sustainment supports, but the action of sustainment is to maintain ongoing support.
