Record the first shot
Start a shot record before touching the gun controls. Write the operation, target wording, observation point, map scale, range reading, elevation state, and shell label. This gives the miss a context that can be checked instead of remembered.
- Copy the target description from the current task and add the landmark or map reference you used.
- Keep the two map references and observation point together; do not transfer only a single distance.
- Record the visible firing inputs before the round leaves the tube.
- After impact, classify the result as short, long, left, right, target effect, or unclear.
The first shot is evidence about this mission and setup, not proof of a universal firing table.
Read the miss in the right order
If the result is long or short, re-check the map scale, reference point, and range reading before changing elevation. If the result is left or right, re-check the observation point and lateral references while keeping the other inputs fixed.
- One variable changed: the next shot can tell you whether that variable mattered.
- Several variables changed: treat the result as inconclusive and rebuild the record.
- The result is unclear: repeat from the same setup before publishing a correction.
Use the field note as the walkthrough output
A useful walkthrough ends with a reproducible record: original input, observed impact, one correction, and the next result. The home-page checker can generate that note, while this page explains how to interpret it during a real operation.
What still needs a current-build test
This page does not publish an exact angle, range conversion, shell multiplier, or guaranteed hit condition. Add those only after repeating the same operation in the current build with a dated record and a source trail.
