What is the primary purpose of an operations order (OPORD)?

The primary purpose of an operations order (OPORD) is to provide detailed instructions for mission execution. OPORDs are essential documents in military operations that outline the plan for a specific mission. They provide clear and precise directions to ensure that all personnel involved understand their roles, the objectives of the operation, and the logistics necessary for successful execution. This includes information about the situation, mission, execution, sustainment, and command structure, ensuring that every team member has the necessary guidance to perform effectively during the mission.

By focusing on detailed instruction, OPORDs facilitate coordination among units and ensure that all actions align with the overall strategy, thereby increasing the likelihood of mission success. The other options, such as summarizing past missions, outlining budget needs, or publishing personnel assignments, do not accurately capture the operational focus and critical function of an OPORD.
