What are the three deviation spottings used in fire support?

The three deviation spottings used in fire support primarily focus on horizontal adjustments to effectively communicate where rounds impact relative to the target. The correct choices are Line, Left, and Right.

"Line" refers to the alignment or the direct path toward the target, while "Left" and "Right" indicate adjustments to the left or right of that line. These terms allow for precise and clear communication between the fire support team and the units on the ground, ensuring that any necessary corrections to the point of aim can be effectively communicated to adjust the fire accordingly.

The importance of these terms stems from the need to convey information concisely under pressure, ensuring that artillery or air support can be adjusted quickly to remain effective on target. "Line" provides the baseline for how to orient the fire, and deviations to the left and right are standard practices to guide corrections while maintaining clarity in the command structure.
