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

In the context of adjusting illumination rounds, Height of Burst (HOB) adjustments are typically made in multiples of 100 meters. This is essential for ensuring that illumination effects are optimized for the battlefield. Adjusting in larger increments allows observers to effectively communicate necessary changes to the artillery units and ensure that the rounds burst at the desired altitude, maximizing visibility and effectiveness in illuminating the target area.

Understanding this standard is crucial for fire support operations, as it simplifies communication and execution of corrections, ensuring that all parties involved can maintain a clear and concise understanding of the required adjustments. Inaccuracies in HOB adjustments can lead to inadequate illumination of the designated area, potentially compromising mission objectives and safety.

In contrast, other options represent smaller increments which, while possibly applicable to other types of adjustments, do not apply specifically to illumination rounds where the requirement is centered around broader adjustments for optimal effectiveness.
