If you measure the angular deviation of a round to be 40 mils to the right, how should you record this spotting?

When recording angular deviation of a round, it's essential to convey the direction and magnitude accurately. In this case, a measurement of 40 mils to the right indicates that the impact point of the round is positioned 40 mils on the right side of the reference point, which is typically the intended target or aiming point.

Recording this deviation as "40 Right" provides a clear and concise representation of the direction and extent of the deviation. This format is standard in military communications to ensure everyone understands the location of the impact relative to the target. By specifying "Right," it removes any ambiguity, making it evident that adjustments will need to be made to the left to correct for this deviation when re-engaging the target.

Using alternatives such as "Left 40" or "40 Left" would incorrectly signify a different direction of deviation. The option stating simply "Right 40" also presents a clear understanding but deviates from the more common convention of stating the magnitude first. Thus, "40 Right" is the most accurate and commonly accepted format for recording the deviation in this scenario.
