What is the purpose of fixed limits?

The purpose of fixed limits, particularly in the context of artillery and machine gun operations, is to set elevation through a specific arc. This is crucial for ensuring that the weapon operates within predetermined parameters, allowing for precise control over the angle and trajectory of fire. By setting these fixed limits, operators can optimize the effectiveness of their fire, ensuring that rounds land within a designated target area while maintaining safety protocols for surrounding troops and equipment.

This also helps mitigate the risks of overshooting or undershooting the target, which can lead to unintended consequences on the battlefield. Properly understanding and utilizing fixed limits enables gunners to maximize their firepower while maintaining control over the weapon system's performance in varying conditions.
