What is the adjustment for one turn of the traversing handwheel on the Lower Saddle?

The adjustment of one turn of the traversing handwheel on the Lower Saddle is 15 mils. This adjustment is crucial because it allows for precise changes in the direction of fire when using mortars. Understanding this adjustment is fundamental for accurate target engagement and effective fire support.

When operating a mortar system, the traversing handwheel is designed to allow gunners to make fine adjustments to the angle of fire. Each complete rotation of the handwheel corresponds to a specific angular change, which enables gunners to effectively track targets and make quick corrections.

Selecting 15 mils reflects a standardized and effective parameter within many mortar systems for adjustments. Other potential adjustment values, such as 5, 10, or 20 mils, may not provide the same level of precision or may not align with the operational guidelines for that particular mortar setup. Hence, 15 mils stands out as the precise figure necessary for conducting accurate and efficient mortars operations.
