When considering sustainment, which elements are included?

• A. Detailed tactical planning for combat.
• B. Strategic communications with allies.
• C. Training, evaluation, and certification.
• D. Maintenance, supply, medical support, and services.

Answer: (D)

Sustainment focuses on keeping the force operating by providing the logistics and support it needs. That includes keeping equipment available and ready (maintenance), ensuring soldiers have the supplies and resources they need (supply), delivering medical care and health services (medical support), and the broad range of field services that support daily operations (services). Together, these elements form the ongoing support system that enables missions to continue.

The other options describe activities outside of sustainment: detailed tactical planning for combat is part of operational planning and execution; strategic communications with allies falls under command and control and coordination; training, evaluation, and certification relates to readiness and personnel development rather than provisioning and support.
