Fire control / target card

Ballistic calculator: keep the map-to-gun handoff intact

The calculator cannot repair a bad map origin. Start with the final red line from the current Nest position, then carry every value forward without substitution.

Draw the red line from the Iron Nest to the fixed target and copy its bearing and range. On the calculator, enter that bearing, choose the target icon if useful, select the intended shell, set the measured range, and choose a charge count the indicator accepts. Pull the calculate-elevation lever, then transfer the resulting card's bearing, charge count and elevation to the same gun you load and arm.

  1. Measure the final firing line

    Use the red pencil from the bottom spike of the current Iron Nest marker to the target. The copied bearing and range are the calculator's primary map inputs.

  2. Enter bearing, target and shell

    Set the bearing first, select the optional target icon, then rotate the shell selector to the round you actually intend to load.

  3. Enter range and choose charges

    Set the Nest-to-target range. Adjust powder charges until the calculator indicates a viable amount; do not silently change the charge count after generating the card.

  4. Generate and carry the card

    Pull the elevation calculation lever. Keep the resulting card visible and transfer its bearing and elevation to the correct cannon while loading the same shell and charge count.

  5. Run the physical pre-fire check

    Confirm target card, range source, shell, charge count, turret bearing, cannon elevation and armed side. A correct card attached to the other gun is still a failed handoff.

  • The map line, calculator bearing and turret bearing all use the same Nest-to-target direction.
  • The loaded shell and powder count match the calculator input.
  • The chosen gun's elevation matches its target card and that gun is armed.
A plausible card produces a huge missReturn to the map origin first. Verify current Nest position, line direction and exact target marker.
The calculator will not accept the charge choiceThe range may exceed that charge count's supported arc. Increase charges or use the in-game indicator.
One gun hits and the other missesEach cannon can carry a different elevation. Match the card, loaded side, elevation control and arming lever.
Settings changed after loadingRecalculate for the values actually loaded rather than assuming the old card still applies.

The official store confirms the core instruments and relationship; detailed control order comes from a current community guide. We do not claim that this workflow guarantees a hit or simulates real-world artillery physics.
