When using the distant aiming point method during boresight procedures, the distant aiming point should be a minimum of how many meters from the weapon system?

In the context of the distant aiming point method during boresight procedures, the minimum distance of 200 meters from the weapon system is crucial for effective targeting and accuracy. The primary reason for this distance is to ensure that the mortar's line of sight and the impacts can be accurately measured and adjusted without interference from immediate terrain features, which could distort the sighting process. By establishing a distant aiming point at a minimum of 200 meters, operators can better achieve a more precise alignment of the weapon system, allowing for effective adjustments that enhance the accuracy of subsequent rounds fired. This distance provides sufficient separation to lessen the influence of parallax and other potential errors that are more pronounced at shorter ranges, thereby securing the reliability of the aiming and firing procedures.
