In a polar plot mission, what term indicates the vertical distance to the target?

In a polar plot mission, the term that indicates the vertical distance to the target is accurately represented by "Elevation." Elevation refers to the height of the target relative to the observer's position and is crucial in targeting and fire support operations. It is measured in feet or meters above a reference point, typically sea level or the observer's location.

Understanding elevation is essential for fire support teams as it directly affects the calculation of the trajectory of projectiles and the dispersion of indirect fire. When working with polar plots in artillery or aviation contexts, knowing the elevation of a target helps ensure accurate targeting and effective engagement.

This aspect of elevation can greatly influence operational success, as missing the correct elevation can result in rounds impacting above or below the target, thereby failing to achieve the intended effects. This is a critical consideration for FIST personnel involved in coordinating fire support and ensuring precision in strike missions.

While the other terms may relate to aspects of targeting or positioning, they do not specifically capture the concept of vertical distance to the target in the context of polar plots.
