Why must a mortar crew know how to perform basic maintenance?

A mortar crew must know how to perform basic maintenance primarily to ensure the weapon's reliability and safety during operations. Mortars, like any other piece of military equipment, are subject to wear and tear, and understanding how to maintain them helps in identifying potential issues before they result in failure. Regular maintenance activities, such as cleaning, lubricating, and inspecting components, are crucial for optimal performance, accuracy, and the overall effectiveness of the weapon system.

Additionally, safety is a paramount concern in any military operation. Proper maintenance minimizes the risk of malfunctions that could endanger the crew or compromise mission objectives. By ensuring that the mortar is functioning correctly, the crew increases not only their own safety but also that of their comrades in the field. Effective maintenance practices are indicative of professionalism and preparedness, which are essential qualities in a mortar crew's operational capability.
