During an illumination mission, if the flare burns out 60 mils above the ground and the OT factor is 2, what correction should the Observer send for HOB?

To determine the appropriate correction for Height of Burst (HOB) during an illumination mission when the flare burns out 60 mils above the ground with an OT (Observer Target) factor of 2, one must first understand the concepts of mils and how the OT factor influences the corrections.

When the flare burns out 60 mils above the target, this measurement indicates how high the illumination is occurring compared to the actual target location on the ground. The OT factor of 2 implies that the observer needs to consider this value when making the necessary adjustments for HOB.

In this case, the adjustment can be calculated by converting the mils into a feet or meters equivalent and then applying the OT factor. The conversion of mils to a corresponding distance involves some calculations, but fundamentally, if 1 mil corresponds to a certain distance based on the range to the target, we can derive that the total distance that corresponds to 60 mils is multiplied by the OT factor of 2.

Using common calculations from military doctrine, if you need to correct for HOB based on the OT factor of 2, the total vertical correction from the original height would mean subtracting 120 feet (or whatever unit is applicable) in total. With the
