How does OPORD differ from CONOP in Marine doctrine?

• A. OPORD is an operations order for an actual mission; CONOP is a concept of operations, a larger planning framework for an operation
• B. OPORD is a preliminary plan; CONOP is an execution order
• C. OPORD is a planning framework; CONOP is an execution order
• D. OPORD and CONOP are interchangeable terms

Answer: (A)

In Marine doctrine, planning versus execution directives is the key idea. A concept of operations lays out the broad approach for how the operation will be conducted—the overall plan, phases, and how forces will work together. An operations order then takes that concept and turns it into a concrete, actionable directive for execution, specifying who does what, when, and with what resources. So the concept of operations guides planning, while the operations order directs actual action on the battlefield. The other possibilities mischaracterize the relationship—for example, treating the operations order as a preliminary plan, or as an execution order, or claiming the two are interchangeable.
