What is "adjust fire" in artillery terms?

"Adjust fire" in artillery terms refers specifically to the modification of firing data based on observations. This process is critical in ensuring the accuracy of artillery strikes. When an initial round is fired, observers assess the impact point and provide feedback on where the rounds landed in relation to the intended target. By analyzing this information, adjustments can be made—such as changing the elevation or deflection of the cannon—so that subsequent rounds will impact closer to the desired target.

The adjustments informed by observations account for variables such as wind, terrain, and target movement, which can significantly affect the trajectory and accuracy of artillery fire. This iterative process allows artillery units to efficiently engage targets while minimizing collateral damage and ammunition expenditure.

Other responses do not accurately describe the process of adjusting fire. Reducing ammunition usage might occur as a consequence of effective adjustments but is not the primary definition. Changing targets mid-mission refers to a different tactical situation where an entirely new target is assigned rather than adjusting for accuracy on an existing one. Waiting for better weather conditions does not align with artillery operations focused on immediate fire support, as adjustments are typically based on observed performance rather than external conditions.
