What does the term "quadrant" refer to in mortar firing?

The term "quadrant" in mortar firing specifically refers to the elevation angle setting used to determine how high the mortar tube is angled to achieve the desired range and trajectory of the projectile. Mortar systems often require precise adjustments in elevation to effectively target objects at varying distances, and these adjustments are typically measured in mils or degrees. Consequently, when a mortar crew refers to "quadrant," they are focusing on the angle at which the mortar will fire, crucial for ensuring that rounds land accurately on the intended target. Understanding this concept is essential for effective mortar operations and targeting, as elevation directly impacts the range and accuracy of the fired rounds.
