REVEAL MAP DETAILS (SPOILER)View possible battlefield locations and mission-specific map information.REVEAL MAP DETAILS
These outlines show the areas from which the mission can select positions. They are possible placement zones, not fixed spawn coordinates. A numbered badge identifies an area; it does not enlarge that area.

- 1Designated target
1 enemy target. Present from mission start.
- 2Hospital
1 hospital. Present from mission start.
- 3City protected-unit areas
8 civilians, 1 propaganda office and 3 police units. Present from mission start; each unit is placed separately within these areas.
- 4Iron Nest
Player firing position. Mission starting position.
The Tactical Map uses a 20 × 10 main grid, with ten subdivisions on each axis inside every square. The overlay follows those same boundaries. Large overlapping allied areas mean that individual units can appear across a broad part of the battlefield.
MISSION WALKTHROUGH
MISSION SPOILERSReveal the complete objective order and firing guidance.REVEAL WALKTHROUGH
Read the order
High Command prints both the Iron Nest position and the target grid. Transfer those two positions to the Tactical Map before preparing the gun.
Calculate the firing solution
Measure the bearing and distance from the Iron Nest to the reported target. Select a powder charge that covers that range, then calculate the required elevation.
Fire HE
The order specifies HE. A miss produces a Field Report asking the Operator to review the Iron Nest position, bearing and range before firing again. Destroying the designated target completes the mission.
Operational notes
- The target is placed through a mission zone, so its precise grid belongs to the current playthrough.
- Miss reports are generated after shell impacts and direct the Operator back to the plotted position and firing solution.
- The mission tracks the number of shots fired for its single medal.
