During an impact registration, how many rounds are fired to establish the initial 50 meter range bracket?

To establish the initial 50-meter range bracket during an impact registration, two rounds are fired. This practice allows the battery to pinpoint the target area accurately by ensuring the first round lands within the correct range and to confirm the initial data received. The first round helps to establish the trend of the shot, while the second round serves to refine the adjustment based on the initial impact. This methodology is crucial as it provides sufficient data to determine if further adjustments are necessary and to establish a reliable range for future targeting efforts.

Firing only one round would not provide enough information to properly gauge the range and adjust for accuracy. Firing three rounds would be excessive for the purpose of establishing just the initial bracket, as the goal is to achieve effective data with the minimum amount of ordnance used in this stage. Thus, the requirement of two rounds effectively meets the operational standard for establishing the initial 50-meter range bracket.
