Protocol
| Step | Station | What to finish before moving on |
|---|---|---|
| 1 | Receiver | Start here: the receiver tells you what target to solve for, what clues you have, and when new threats appear. |
| 2 | Tactical Map | Mark observer reports, triangulate targets, and read range/bearing from Iron Nest to the selected point. |
| 3 | Ballistic Calculator | Enter shell, range, and charge data before moving to the loader and elevation station. |
| 4 | Loader | Pick the shell, add the powder charges from the calculator, and ram the load before aiming. |
| 5 | Rotator | Rotate Iron Nest to the bearing from your map solution. |
| 6 | Elevator | Set the elevation produced by the calculator for the chosen shell and charge. |
| 7 | Trigger | Use only after the solution is checked; in counter-battery missions, the first impact can start the timer. |
Shot verification
A complete shot has four numbers or choices locked in: shell type, powder charge, bearing, and elevation. The Ballistic Calculator only helps if the range and shell type match what you actually load.
