Phantom Battery is a timed hunt, not a normal fixed-target mission. The reliable route is to complete the ordered relocation, establish your new position, use spotters or reconnaissance to find the hostile Nest, prepare both guns before committing, and reacquire the battery when it moves. Current player reports agree on that structure, but not on a universal grid: the enemy position and useful reconnaissance lanes can vary between runs.
2950790, Windows public version 1.0, checked 2026-08-11 after PATCH 1.0 (1577). The operation name and Master Gunner achievement are official. The route below is community-corroborated across several current full-release discussions; exact grids, costs, shell counts, and timing remain run-specific.Stabilize after the opening relocation
Follow the teleprinter’s relocation order before building a detailed firing solution. Wait for the Nest to settle and for the violent movement to stop. If the screen continues shaking after the move finishes, pause long enough to distinguish the relocation sequence from an actual persistent input or visual problem.
Your old Nest-to-target measurements are invalid after any move. Keep enemy observations, but discard every firing line that began at the former Nest position. Read the position information supplied in the turret and use Position Report or the mission’s current location tools when available. A correct target with an incorrect firing origin still produces a miss.
Buy time by finding enemy spotters
The counter-battery timer is the mission’s immediate pressure. Several current players report that destroying hostile spotters extends the working window and can return requisition, making them useful targets rather than optional scenery. Use Forward Observer information or a reconnaissance pass to reveal likely spotter areas, then engage the clearest targets you can solve quickly.
Do not spend the entire opening plotting every possible observer. The purpose of the spotter phase is to create enough time and resources to locate the hostile Iron Nest. If a spotter requires a long uncertain solution, a broader reconnaissance lane may be a better purchase.
Search for the Phantom along an evidence lane
Use a Forward Observer to obtain a useful direction when the ability is available, then send reconnaissance through the corresponding map strip. Popular community routes mention northern passes through columns near the far side of the map, but those reports disagree on the exact column. Treat those letters as examples, not coordinates.
A good reconnaissance request has a reason: it crosses a bearing from an observer, covers several suspected spotters, or follows the hostile battery’s last known movement. When the photograph or map response arrives, mark the hostile Nest separately from observer positions. Confirm that the icon or message identifies the battery before spending the prepared salvo.
If no battery appears, do not immediately restart. Check whether the plane covered the intended bearing, whether your own location is correct, and whether a newly revealed spotter can fund another search. A failed pass still narrows the map.
Prepare the strike before starting the final calculation
Current successful reports commonly use penetrating ammunition such as AP or APHE and take advantage of both guns. The community disagrees about exact shell counts and whether attacking spotters first is mandatory, so the safe rule is to read the live target classification and load both barrels for the same confirmed hostile Nest only when the mission supports that effect.
Do the expensive mechanical work early: acquire the shells and charges, load each side, and keep left/right states written separately. Once recon confirms the Phantom, draw a fresh line from your current Nest origin, calculate the solution for the actual load, set both guns deliberately, and arm both only after each side matches its firing card.
A dual shot reduces the time exposed between impacts, but it doubles the cost of a bad plot. If your position or target is still uncertain, validate with one gun and preserve the second.
Reacquire the battery after it moves
After a successful strike, stop and read the teleprinter. Several full-release reports say the hostile battery relocates rather than remaining on the first impact point. The next dispatch is the cue to scout again. Send reconnaissance along the previous movement lane or use the new observer information; do not assume the battery moved a fixed number of grids.
Keep the old position marked as inactive. The crater, previous recon result, and reported movement direction can constrain the second search. When the new battery position is confirmed, repeat the complete Nest-to-target measurement. Your Nest may not have moved, but the target did, so the old bearing and elevation are stale.
Recover from the common failure states
- Destroyed before a firing solution: prioritize one confirmed spotter or a focused recon lane instead of building a perfect full-map plot.
- Recon found only spotters: use them as targets to buy time, then send the next pass from the new evidence rather than repeating the same request.
- Both shells missed together: recheck your Nest origin, target identification, bearing, and actual charges before spending another pair.
- First hit registered but the next volley missed: the Phantom probably moved; wait for the dispatch and reacquire it.
- Mission replay behaves differently: PATCH 1.0 (1577) officially fixed mission events not resetting correctly when replaying the same mission and turret movement/position not resetting between missions. Update before comparing a replay with an older run.
- A copied coordinate fails: the mission state, enemy position, recon lane, or patch can differ. Use the coordinate only as a search hypothesis.
Master Gunner and medal attempts
Steam’s official Master Gunner achievement requires gold on all Phantom Battery medals. It does not publish the thresholds. A current community medal guide reports categories involving no-recon kills, total enemies, average accuracy, and counter-battery time, but those values are community-reported and can be affected by bugs or patches.
Complete the mission once before optimizing. On a medal run, capture the result screen and change one variable at a time. A fast recon-heavy completion can teach the route even if a no-recon medal later requires a different plan. Use the Gold Medal Guide for the evidence and save discipline needed across attempts.
Phantom Battery questions
Is the Phantom always in the same grid?
No reliable current evidence supports one universal coordinate. Community successes describe different useful recon strips and movement outcomes. Use observer information and recon to establish the position in your run.
Should I destroy spotters or rush the hostile Nest?
Both routes are reported. Spotters buy time and resources when your search is slow; a direct strike is faster when recon already reveals the Nest and both guns are ready. Choose based on what is confirmed, not on a fixed script.
Why did the second salvo hit nothing?
The battery can relocate after being struck. Read the new teleprinter message, mark the old position inactive, scout again, and rebuild the solution.
Does PATCH 1577 reveal the Phantom?
No. Its official notes cover replay event resets and turret movement/position resets between missions. The off-centre spotter fix specifically names Blindfire, not Phantom Battery.
