What is Sustainment described as in the operation order?

• A. Explicit
• B. Implied
• C. Not applicable
• D. Overlooked

Answer: (B)

In an OPORD, sustainment is treated as implied rather than spelled out in detail. The order focuses on the mission, the concept of operations, and the tasks to subordinate units, while the logistics and support elements are planned and coordinated by the sustainment staff and addressed in separate logistics annexes. This means the necessary supply, maintenance, transportation, medical, and other support are assumed to be provided to enable the operation, rather than being itemized step by step in the main order. The concept is clear enough to ensure units know support exists and how it will be organized, but the specifics are captured elsewhere, not in the body of the order itself.
