During training operations, what is the function of the WARNO/OPORD?

The function of the WARNO (Warning Order) and OPORD (Operations Order) during training operations is to provide mission orders. This is essential because these documents communicate critical information about the mission objectives, tasks, and intentions to all involved personnel. The WARNO serves as an early alert to inform units of impending operations and prepare them accordingly. Meanwhile, the OPORD outlines the detailed execution of the mission, specifying roles, responsibilities, and timelines necessary for effective action. This clarity and direction are crucial during training to ensure that all participants are aligned with the mission goals and can execute their roles effectively.

Other options, while they may relate to aspects of operational planning or performance, do not capture the primary role of WARNO and OPORD in training operations. For instance, limiting operational scope is a tactical consideration that doesn’t encompass the full breadth of mission orders. Initiating rest periods is more about personnel management rather than mission execution, and evaluating performance metrics falls under assessment processes rather than the direct role of mission orders.
