Which component is essential for aiming a mortar during operation?

The mortar base plate is critical for aiming a mortar during operation because it serves as the foundation of the mortar system. When the mortar is fired, the base plate stabilizes the weapon and absorbs the recoil, allowing for accurate placement. Proper positioning and leveling of the mortar using the base plate enables the gunner to determine the appropriate angle for elevation and traverse, which is necessary for hitting the intended target.

While other components, such as the vision scope, ballistic computer, and fire control panel, play important roles in the firing process—like assisting with targeting, calculations, and fire direction—they do not serve the essential function of establishing a stable firing platform. Without a properly set base plate, the mortar would not be able to deliver consistent, accurate fire, highlighting its fundamental importance in mortar operations.
