When operating the 120mm mortar, each turn of the traversing handwheel moves the bore approximately how many mils?

When operating the 120mm mortar, each turn of the traversing handwheel moves the bore approximately 5 mils. This measurement is crucial for precision aiming and ensures that the mortar can be adjusted accurately for the intended target. Mils, which are a unit of angular measurement used in artillery, allow gunners to make adjustments based on how far they want the projectile to travel horizontally.

Understanding that 5 mils is the standard adjustment per complete turn of the handwheel helps operators maintain spatial awareness and precision when coordinating fire missions. This knowledge is vital in a combat scenario where every adjustment matters significantly. Proper training in managing these mechanical adjustments ensures that the mortar crew can effectively engage targets at varying distances accurately.
