How do soldiers determine the direction to aim a mortar?

Determining the direction to aim a mortar is a critical skill that ensures accuracy and effectiveness in combat situations. The correct approach for soldiers to achieve this is by utilizing a compass and known coordinates. This method involves calculating the required azimuth from the mortar's current location to the target, ensuring precise alignment.

Using a compass allows soldiers to orient themselves accurately and understand the terrain they are operating in, while known coordinates provide a definitive point of reference for the target location. This combination enables a reliable aiming solution that takes into account the necessary adjustments for various factors such as wind, elevation, and distance.

In contrast, estimating from memory can lead to significant inaccuracies, as human recollection is often unreliable in high-stress situations. Measuring past impact sites might provide some insight into adjustments needed, but it lacks the precision necessary for targeting distant or moving objectives, and does not account for changes in conditions. Relying solely on visual spotting can also be problematic due to potential misinterpretations of distance or environmental factors that obscure visibility.

The use of a compass and known coordinates is therefore the most systematic and accurate means of determining the correct direction for mortar aiming, which is vital for maximizing effectiveness and minimizing risk in military operations.
