What is the objective of the time portion of the precision registration?

The objective of precision registration in artillery is to accurately determine and confirm the data necessary for delivering fire on target, ensuring that the rounds fall within the desired parameters to successfully engage the enemy. The practice of firing four rounds with the same data, specifically 20 meters above the registration point, serves to establish a reliable reference for the impact of the rounds, allowing for corrections and adjustments based on observed effects.

By firing four rounds, the registration can create a clearer picture of the projectile's flight path and impact pattern. The dispersion from this higher elevation assists in validating the accuracy of the data used for targeting. The choice of 20 meters above the point also helps avoid immediate interference with ground-level objects, ensuring that the impacts can be assessed without chaotic influences. This methodical approach results in a more robust and repeatable calculation of the necessary adjustments for subsequent fire missions.

This process emphasizes the importance of accuracy and repeatability in artillery operations, thereby enhancing the effectiveness of subsequent fire support. The other options either change the number of rounds or the height above the registration point, which could compromise the precision of the registration process and might not provide the necessary confirmation of data accuracy for effective artillery support.
