IMPACT REGISTRATION 5-66. The objective of a registration is to get spottings of four rounds (two overs and two shorts) along the observer-target line from rounds fired with the same data or from rounds fired with data 25 meters apart (50 meters apart when PER is greater than or equal to 25 meters). Normally this requires the spottings from four separate rounds. However, a target hit or a round spotted as range correct provides spottings for both over and short. Thus, the observer could achieve the objective with two consecutive target hits or range correct spottings. 5-67. The observer spots the rounds for deviation to the nearest one mil and brings the rounds onto the observer-target line before splitting a 200 meter bracket. As a rule of thumb, the observer should not make deviation corrections after establishing a 200 meter bracket. Once the observer brings the rounds onto the observer-target line, the deviation is measured and recorded but makes no correction. If the range spotting is doubtful, the observer corrects for deviation only. If the observer makes a deviation correction after a 200 meter bracket is established, no previous rounds, including the last round fired, are usable rounds for determining range and deviation refinement data.
