What is the elevation setting on number 1 for zeroing the PKM?

The elevation setting on number 1 for zeroing the PKM is set to 1. This setting is crucial as it dictates the initial adjustment of the weapon's sights to align the point of impact with the point of aim effectively. For the PKM, which is a general-purpose machine gun used in various terrains and combat situations, the elevation setting helps account for the effects of gravity on the bullet's trajectory.

Setting the elevation to 1 means that the weapon is calibrated for effective engagement within a specific range, typically ensuring that shots land on target at closer distances where the trajectory is relatively flat. It is essential for gunners to understand these settings to achieve accurate fire and enhance their combat effectiveness. This foundational knowledge plays a critical role in training and operational readiness with the PKM, allowing personnel to function confidently and efficiently in dynamic scenarios.
