Vertical shift is sent in the target location if the difference in vertical shift is greater than or equal to how many meters?

The correct answer indicates that a vertical shift is sent in the target location if the difference in vertical shift is greater than or equal to 35 meters, primarily because this threshold is significant enough to warrant a communication regarding adjustments to the fire support.

In fire support operations, effective engagement of targets often requires precise vertical adjustments based on varying terrain and atmospheric conditions. The decision to communicate a vertical shift reflects the need to ensure that artillery fire accurately impacts the intended target. A difference of 35 meters is typically recognized as a critical threshold where failure to adjust for this change could result in missing the target or creating unintended consequences in the area of operations.

The second part of the answer, which states 5 meters, often applies to smaller adjustments. However, when dealing with a significant visual or range difference, relying solely on minor adjustments could be ineffective, which is why the higher value of 35 meters is the focus when communicating necessary shifts in targeting information. This illustrates how artillery is not only about hitting a target but doing so with a level of confidence in the adjustments of the data used in fire missions.
