When using the compass direction method for adjusting close air support, what must you do first?

The first step in the compass direction method for adjusting close air support involves observing the last hit. This step is crucial because it helps establish a reference point for subsequent adjustments. By identifying where the last round impacted, you can determine the effectiveness of the previous engagement and assess how close the munitions were to the intended target. This information allows for more accurate adjustments in terms of direction and distance, ensuring that any further strikes can be effectively directed towards the target.

Once the last hit is observed, additional steps such as identifying the target and communicating with the pilot will follow, but these actions rely on the understanding of where the previous munitions fell. This systematic approach is essential to maximize the efficacy and safety of close air support operations.
