What are the three types of deviation spottings?

The three types of deviation spottings are identified as Line, Left, and Right. This classification is used within the context of artillery and target acquisition to describe how a projectile may deviate from the intended flight path.

"Line" refers to the vertical alignment of the shot concerning the target's axis, indicating whether the shot is on target or off in terms of elevation. "Left" and "Right" specifically pertain to the horizontal deviation. When a projectile falls to the left of the target, it is categorized as left deviation, while a right deviation indicates the projectile has landed to the right side of the target. Understanding these types of deviation is crucial for artillery personnel to make the necessary adjustments to achieve accuracy and improve targeting effectiveness.

The other options, while they may involve directional terms, do not correctly align with the established artillery terminology related to deviation spotting.
