Sustainment in military operations is defined as what?

• A. The navigation of joint international forces.
• B. The development of new weapons.
• C. The planning of offensive campaigns.
• D. The provision of logistics and personnel support to sustain operations.

Answer: (D)

Sustainment is the logistics and personnel support that keeps military operations going over time. It ensures the force has what it needs—food, fuel, ammunition, maintenance, transportation, medical care, and administrative services like pay and personnel support—so units can operate, re-supply, and endure under stress. This practical provisioning enables sustained action, rapid redeployment, and continued combat or mission effectiveness. The other options describe movement, capability development, or campaign design, which are important in their own right but do not capture the ongoing support that sustains operations.
