You are adjusting a time round and the spotting is a graze. What is your automatic correction after already having a previous airburst?

• A. Up 10
• B. No correction
• C. Up 20
• D. Down 20

Answer: (C)

The key idea is how to apply automatic fuse adjustments for time-on-target rounds based on what you spot, especially after you’ve already had an airburst. A graze means the burst occurred near the target but didn’t land on it, so you need a corrective step that nudges the next round toward the target area. With a prior airburst, the standard automatic correction is to increase the fuse timing by 20. That longer fuse delays the detonation, which shifts the burst downward toward the target zone and improves the chance of hitting or near-hitting on the next shot. So moving the fuse up by 20 is the correct adjustment to use in this situation.
