Which joint function would primarily ensure the continued supply of logistics and personnel services?

• A. Information
• B. Sustainment
• C. ISR
• D. Fires

Answer: (B)

Sustainment is the joint function focused on keeping operations going by providing the logistics and personnel support that forces need. It covers not only the supply chain—fuel, ammunition, parts, food, maintenance, transportation—but also personnel services such as human resources, pay, medical, and morale support. By planning, coordinating, and delivering these readiness enablers, sustainment ensures units have what they need when they need it, allowing operations to continue smoothly. Information, ISR, and fires play important roles in command, intelligence, and combat power, but they do not primarily ensure the ongoing provisioning of logistics and personnel services. Information supports decision-making and communication; ISR focuses on gathering intelligence; fires delivers combat effects.
