What is the purpose of a combat order?

A combat order serves a vital function in military operations by providing direction and communication regarding the tasks, objectives, and intentions involved in an upcoming mission. It is a crucial tool for ensuring that all members of a unit understand their roles, the overall strategy, and specific operational details necessary for successful execution. The combat order establishes a common understanding among all personnel and ensures that they are synchronized in their efforts to accomplish the mission.

The other options, while they may involve aspects of military operations, do not capture the primary purpose of a combat order. The history of military operations is more suited to after-action reports or historical documentation rather than the active communication required for an operation. Designating supply routes is an essential logistical function, but it is only one aspect of what a combat order encompasses, which is broader in scope. Lastly, recording engagement outcomes pertains to post-mission analysis rather than the proactive and directive nature of a combat order, which focuses on planning and execution prior to operations.
