Which items constitute the first transmission of a Call for Fire?

• A. Target location
• B. Time of flight
• C. Observer ID and WARNO
• D. Description

Answer: (C)

The first transmission of a Call for Fire is about establishing who is calling and what the initial mission intent is. The observer’s identity confirms who is requesting the fire mission, and the WARNO (warning order) conveys the leader’s intent, any immediate constraints, timing, and safety considerations so the battery knows how to prepare and react. With this basic frame set, the fire direction center can prioritize the request, assign the correct team, and ensure everyone is aware of the broad parameters before moving on to specific targeting data. Target location, target description, and other fire data come in subsequent transmissions once the initial call has been established.
