Sustainment focuses on which activity?

• A. The planning and execution of logistics and support to maintain operations.
• B. The use of all weapon systems to achieve effects on targets.
• C. Measures to preserve the force and mission by reducing risk.
• D. Delegating authority to subordinates to execute tasks.

Answer: (B)

Sustainment is about keeping the force operating by providing the logistics and ongoing support needed to maintain missions. It covers planning and executing provisioning, maintenance, transportation, supply distribution, medical and health services, and other support functions that keep operations going over time. Describing the use of all weapon systems to achieve effects on targets fits the fires function, not sustainment. Measures to preserve the force by reducing risk align with protection and risk management, while delegating authority to subordinates is a leadership/command activity. In practice, sustainment ensures continuous readiness and endurance by enabling ongoing supply, repair, movement, and support services so operations can continue without interruption.
