When two airbursts and two graze bursts are spotted, what is the HOB correction?

When analyzing the situation where two airbursts and two graze bursts are observed, it is important to understand the concept of Height of Burst (HOB) correction in fire support operations. In this case, having both airburst and graze bursts indicates the need to adjust the firing parameters to optimize the effects on the target.

The standard practice calls for a specific HOB correction based on the types of bursts seen. With two airbursts, which are designed to maximize the area of effect over the target, and two graze bursts that tend to land closer to the ground, the combined observation informs the necessary correction.

The HOB correction of "Up 10" signifies an adjustment to increase the burst height to improve effectiveness, particularly in achieving a more concentrated impact on the target area. In scenarios like this, an upward adjustment typically compensates for discrepancies in the observed burst patterns to better align the artillery or airstrike with the intended target, ensuring that the explosive effects are maximized at an appropriate altitude.

This understanding is critical in the field, where rapid and accurate adjustments can significantly influence mission outcomes. Thus, applying an upward correction of 10 to the height of burst is the appropriate action to take in this scenario.
