When adjusting illumination rounds, what are HOB corrections sent in multiples of?

When adjusting illumination rounds, the height of burst (HOB) corrections are specifically sent in multiples of 100 meters. This standard helps ensure that the illumination rounds achieve the desired effectiveness and operate within the intended operational parameters. The use of 100 meters as the adjustment increment allows for a significant and clear adjustment to the burst height, facilitating more precise targeting in the challenging environments where illumination is needed.

This method of using 100 meters provides better control over the effects of the illumination, ensuring that it covers the intended area and meets the tactical requirements. It is critical for effective fire mission execution, particularly in conditions where visibility is compromised, and precise targeting is necessary to support ground operations.
