Final answer:
The WARNORD format option refers to a Warning Order in the military, providing preliminary information about an upcoming mission, enabling units to begin preparations before receiving a full operations order.
Step-by-step explanation:
The WARNORD format option typically refers to a Warning Order in a military context. It is a preliminary notice given to units about an upcoming mission or operation.
While it is not a formal requirement, a WARNORD includes essential information that allows a unit to prepare for future orders without the exhaustive details of a full operations order (OPORD).
A WARNORD often contains the nature of the operation, tentative timelines, anticipated actions, initial instructions, and key leader information. This kind of format allows units to begin preparation while awaiting further details.
