If you measure an angular deviation to be 40 mils to the right, how would you record this spotting?

When recording an angular deviation that is measured to be 40 mils to the right, the correct notation captures both the magnitude and the direction clearly for effective communication in a military context. Recording it as "Right 40" directly indicates the direction and the extent of the deviation. This standardization in notation avoids ambiguity, allowing other personnel to quickly understand the nature of the adjustment required.

Using "Right 40" aligns with commonly accepted conventions in military operations when working with angular measurements, ensuring uniformity and clarity in communication. This is critical in artillery operations, where precise spotting information is crucial for adjusting fire and achieving accuracy on target.
