What is the main purpose of an Operation Order (OPORD)?

The main purpose of an Operation Order (OPORD) is to give detailed instructions to achieve a specific objective. An OPORD serves as a comprehensive guide for military operations, clearly outlining the intent, tasks, and coordination necessary for a successful mission. It includes elements such as the situation, mission, execution, sustainment, and command and signal, ensuring that all participants understand their roles and responsibilities. This structured format allows for efficient communication and coordination among units, helping them focus their efforts toward a common goal.

While summarizing a unit's history, reporting logistics, or evaluating past missions might be important in their own right, they do not encapsulate the primary function of an OPORD, which is to direct and facilitate real-time operations.
