How does joint sustainment differ from single-service sustainment?

• A. Requires coordination across services and agencies, sharing assets and information to support joint forces.
• B. Operates only within a single service's supply chain.
• C. Does not require any cross-agency communication.
• D. Relies solely on local contractors.

Answer: (A)

Joint sustainment means coordinating logistics across multiple services and other involved agencies to support a common mission, using shared assets and information to keep the joint force supplied and ready. It relies on interoperable systems, unified planning, and the ability to draw on the best capabilities from Army, Navy, Air Force, Marines, and civilian contractors as needed, so the whole force can operate effectively together. That’s why this option is the best: it explicitly captures the need for cross-service and cross-agency coordination and the sharing of assets and information to sustain joint forces. Limiting sustainment to a single service’s supply chain misses the collaborative nature of joint operations. Say you don’t communicate across agencies, or you rely only on local contractors—those approaches break the interconnected support network required for joint actions and prevent optimal use of all available resources.
