In the case of one airburst and three graze bursts spotted during registration, what is the HOB correction?

In the scenario described with one airburst and three graze bursts during registration, the height of burst (HOB) correction is critical in ensuring effective targeting adjustments. When dealing with simultaneous airbursts and graze bursts, the standard correction applied is influenced by the need to optimize the detonation height for maximizing the effectiveness of the artillery rounds.

For an aerial burst that is typically higher than desired, a correction must be issued. In this case, the presence of one airburst indicates that the rounds are detonating way above the ground level, leading to less effective coverage of the target area. Each airburst generally leads to an upward adjustment, as airbursts are less effective in low target areas.

Given that there are three graze bursts, which provide a baseline for the desired detonation height, the calculated correction would then sum these adjustments. A single airburst generally incurs a greater need for correction. Therefore, to correct for one airburst and three graze bursts, an upward adjustment of 20 units is typically required for the airburst itself. However, in some guidance structures, this can be interpreted in a more conservative manner where cumulative adjustments lead to an overall correction of 40, capturing the necessary alterations due to the mix of burst
