What information does the FDC typically rely on from the observer to compute firing data?

• A. Target location and description, and any required corrections or safety information
• B. Wind speed and humidity
• C. Time of day and weather only
• D. The color of the projectile

Answer: (A)

The essential data the observer provides are the target location (and a clear description of the target) along with any corrections or safety information. With a precise target location, the FDC can plot where the round must go. The target description helps confirm what is being fired at, ensuring the right aim point and appropriate firing data. Any required corrections—such as range adjustments, anticipated target movement, or wind corrections—and safety information (hazards, friendly positions, restrictions) feed directly into calculating the proper elevation, deflection, fuse, and charge. Wind and other weather factors matter, but they come from meteorological data and the correction process rather than being the observer’s primary input for computing firing data. Time of day and weather alone don’t give the target location or adjustments needed, and the color of the projectile is not part of the firing solution.
