What does firing data consist of and how is it used by gunners?

• A. The azimuth, range, and elevation they must set to lay the gun and deliver rounds.
• B. The wind speed, target color, and weather conditions.
• C. The time of day, moon phase, and humidity.
• D. The crew's radio call signs and the gun serial number.

Answer: (B)

Firing data are the numbers the crew uses to position the weapon and deliver rounds on target. The essential pieces are the direction to the target (azimuth), how far away the target is (range), and the vertical angle to set the barrel (elevation) so the round follows the intended trajectory. The fire-control system or firing tables translate the target location into those three settings, and then the gun is laid accordingly to reach the target. Weather and wind matter because they influence the trajectory—gunners factor wind speed and other conditions into the ballistic solution so the azimuth, range, and elevation corrections correctly hit the target. The other factors listed, like target color or time of day, don’t determine the gun’s aiming settings.
