What is the primary purpose of a WARNO?

The primary purpose of a WARNO, or Warning Order, is to provide key information for preparation. A WARNO is an essential communication tool used by military leaders to inform subordinate units about an upcoming operation, allowing them to begin preparations without waiting for a more formal order. This includes details such as the mission type, the timeline, and any initial instructions necessary for units to start their planning and logistical arrangements.

By delivering this information early, a WARNO helps to streamline the overall mission execution process and ensures that all units involved are on the same page regarding expectations and timelines. The emphasis on preparation is crucial because effective military operations depend on well-coordinated actions, and a WARNO serves as a catalyst for that coordination.

In contrast, issuing commands, preparing a lesson plan, or evaluating mission readiness are related functional aspects but do not capture the essence of the WARNO's primary role, which is to facilitate readiness through key informational updates.
