Deviation correction is calculated by multiplying which two values?

Deviation correction is calculated by multiplying which two values?

• A. OT factor times spotting
• B. Distance times OT factor
• C. Spotting divided by OT factor
• D. OT factor plus spotting

Answer: (A)

The idea is to turn the observed miss into a corrective fire instruction by scaling the spotting with a conversion factor. The OT factor serves as a scale that translates how much of a correction corresponds to a given observed deviation, taking into account the gun, sight, range, and ballistic setup. So the deviation correction is found by multiplying the amount you spotted (how far off the shot was) by this factor. If you spot a larger miss, the correction grows proportionally with the OT factor, giving the proper adjustment to apply to the gun or aim point. Why this fits better than the other approaches: using distance alone would mix range with the lateral/elevation error; dividing the spotting would under- or over-correct since it changes the scale; and adding would not reflect how a measured deviation is converted into a firing adjustment. The correct method keeps the correction proportional to the observed error through the OT factor, yielding the proper deviation correction.
