Which artillery component is responsible for displaying firing data to the gunner?

The gunner's display is the component specifically designed to present firing data to the gunner in an artillery system. This display provides crucial information such as the anticipated trajectory, target coordinates, and necessary adjustments for aiming and firing the artillery piece. By having this information readily accessible, the gunner can make informed decisions and ensure accurate targeting, which is essential for mission success.

The other options include components that have different roles within the artillery system. The fire control computer processes various inputs to optimize fire solutions but does not directly relay that information in a way that is intuitive for the gunner during operations. The munitions container is related to the storage and handling of ammunition and does not interact with the firing data display. The firing mechanism pertains to the physical act of firing the weapon, but it does not involve data display or analysis. Thus, the gunner's display is the key interface for delivering firing data directly to the gunner.
