What document provides detailed operational plans and tasks those involved to prepare for an operation?

The correct answer is that the document that provides detailed operational plans and tasks for those involved to prepare for an operation is an Operations Order (OPORD). An OPORD is a directive issued by a commander that outlines the coordinated effort of forces to be executed during an operation. This document provides a clear framework for what needs to be done, who is responsible for what tasks, and the specific timelines for completion, facilitating effective planning and execution of military operations.

An OPORD typically includes essential elements such as the situation, mission, execution, sustainment, and command and signal aspects. This ensures all participants in an operation are aligned with the mission objectives and can collaborate effectively.

While other documents like EXORDs, Courses of Action (COAs), and Strategy Documents play roles in military planning and decision-making, they do not provide the same level of detail regarding the operational execution and assigned tasks that an OPORD does. An EXORD, for instance, is more focused on the execution of the directives rather than the detailed planning tasks. COAs provide possible strategies for achieving an objective but do not constitute a firm plan. Strategy documents serve a broader purpose encompassing long-term goals and overall military strategy, rather than the specifics required for immediate operational readiness.
