What is the purpose of a Warning Order (WARNO) in a CFF?

• A. To cancel an engagement
• B. To alert the firing unit and provide essential details to begin engagement
• C. To request air support
• D. To designate a target

Answer: (B)

In a CFF, the warning order is about preparation and synchronization. It serves to alert the firing unit that a call for fire is imminent and to pass the essential information needed to begin the engagement. This typically includes the target location or description, any timing to engage, and key constraints or safety considerations. By giving these details early, the firing unit can start the necessary preparations—checking communication links, positioning, ammunition readiness, and coordinating with maneuver units—so that once the observer designates the target and issues the fire mission, rounds can be fired quickly and accurately. It isn’t about canceling an engagement, requesting air support, or designating a target; those actions occur through other parts of the process. The WARNO, then, is the heads-up that aligns everyone involved for a timely, synchronized start.
