What are the two types of adjustment used in fire support?

The two primary types of adjustment used in fire support are accurately characterized by deviation and range.

Deviation refers to the horizontal adjustments made to ensure that fire accurately lands on the intended target or area. This encompasses the lateral movement necessary due to factors like wind or miscalculations in the original firing data.

Range, on the other hand, pertains to the vertical adjustments required to ensure that rounds land at the correct distance from the firing point to the target. This adjustment addresses elevation, and it is crucial for delivering effective fire onto the target, particularly when accounting for terrain features or changes in target location.

Together, these adjustments ensure that the fire support provided is effective, precise, and able to engage targets successfully while minimizing the risk to friendly forces and collateral damage. Understanding these concepts is vital for anyone involved in coordinating and calling for fire support in an operational environment.
