The objective of an impact registration is to achieve spottings that help establish the exact range to the target along the observer-target line, which involves identifying rounds that land both over and short of the target. The goal is to obtain a broader understanding of the impact points to accurately adjust fire for subsequent rounds.

Having four rounds registered—two that land over the target and two that land short—provides a more comprehensive data set for determining the correct range. This allows the observer to verify the necessary adjustments needed to get a direct hit on the target. Such data not only aids in achieving precision, but it also enhances the fire support team’s capability to make informed corrections based on the observed impacts. By confirming the impacts in both directions (over and short), the fire support team can more reliably calculate the necessary adjustments for accurate targeting.
