Which component does the A-Gunner apply the announced Quadrant to after receiving a fire mission?

• A. Caisson
• B. Lanyard
• C. Propellant tray
• D. M18A1 Fire Control Quadrant

Answer: (D)

The announced Quadrant is the input you use to set the gun’s fire control data. After the fire mission is received, the A-Gunner takes that Quadrant value and applies it to the M18A1 Fire Control Quadrant, turning and aligning the dial to the announced number so the fire-control system is correctly set for that mission. This device is specifically designed to carry and transmit the quadrant information into the gun’s aiming and firing calculations, ensuring the crew uses the right quadrant for elevation and deflection. The other components handle ammunition and safety functions—caisson stores rounds, the lanyard relates to arming or safety actions, and the propellant tray holds the charges—not to entering or applying the Quadrant value.
