Which deviation spotting indicates that a round impacted short of the adjusting point?

The correct answer is that there is no deviation spotting term that specifically indicates that a round impacted short of the adjusting point. In artillery terms, deviations such as "left," "right," and "line" typically relate to the horizontal and vertical placement of a round concerning the target or adjusting point, but they don't explicitly address distance.

When a round impacts short, it means that it did not travel far enough to reach the target area, and this is generally indicated by a specific term, often referred to as "short." Since "short" is not among the provided choices, selecting "none of the above" accurately reflects that there is no correct term in the provided options to indicate a short impact. Therefore, understanding the difference between horizontal deviations and the more critical vertical deviations is crucial for interpreting the results of an artillery strike correctly.
