If you are adjusting a time round and the spotting is a graze with a previous airburst, what is your automatic correction?

When adjusting a time round after observing a graze spot following a previous airburst, the automatic correction is to adjust up by 20. This is based on understanding how the different types of rounds function.

In this scenario, the graze indicates that the round impacted the ground at a very low angle, and since you've already had an airburst, you would want to raise your aim point significantly to ensure that the burst will occur effectively above the target area. The up 20 adjustment compensates for the preceding airburst and is intended to achieve a more advantageous detonation that will cover the target area more widely.

This standard practice ensures that engagement remains effective, as further rounds are adjusted based on the type of observations made. Achieving the correct elevation is vital in maximizing the effectiveness of fire support in different environmental contexts.
