Quick Answer
In Iron Road, destroy both armored pillboxes with AP before sounding the war horn, and deal with the inbound reinforcement train before it strengthens the town. A track hit can derail the train, but surviving troops may emerge, so keep HE or HCHE available for soft targets. The mission starts with 300 requisition and 12 powder charges. Three early horn signals while either pillbox remains active end the attempt. Once the approach is clear, signal the assault; enemies left in town are optional after primary completion. Review the four medals independently rather than letting a fast clear obscure ally safety or efficiency.

Step-by-Step Route
- Open by identifying the two armored pillboxes as the hard release condition. Put two separate boxes on your run note, because the horn remains unsafe until both have been confirmed destroyed.
- Record the 300 requisition pool and 12-charge quota before selecting ammunition. Reserve a visible portion of the charge plan for the moving train and any troops that survive a derailment.
- Assign AP to the two armored emplacements. Keep HE and HCHE in a different mental lane for infantry, rail survivors, and other soft targets rather than spending them against the blockers.
- Locate the inbound train path from the live mission view and monitor its timed straight-line approach. Do not convert the route into a guessed coordinate or rely on a remembered impact point.
- Engage the first pillbox with AP, then wait for mission feedback that confirms its destruction. An impact is not the same state as a neutralized emplacement.
- Repeat the confirmation cycle on the second pillbox. Keep the horn untouched even if the first position is gone and allied momentum makes an early signal tempting.
- Check the train state between hard-target engagements. If a track hit derails it, immediately change the entry from moving train to derailment with possible surviving reinforcements.
- Use HE or HCHE against exposed soft targets when needed, especially troops released from the rail cars. Preserve AP for any armored work that still remains unresolved.
- Reconcile both pillbox boxes, the train line, ally safety, and remaining charges before authorizing the assault. The release decision needs four positive checks, not a general impression that the road looks quieter.
- Sound the war horn only after both armored blockers are confirmed gone. Remember that three premature signals while either survives fail the mission, so the horn is a state transition rather than a probe.
- Watch the allied advance and verify that the approach has become passable. Primary completion depends on clearing that operational path, not necessarily erasing every enemy inside the town.
- After the clear, decide whether optional town cleanup serves a medal attempt. Compare expected kills, streak continuity, recon use, and shots before committing limited charges.
- At results, review all four medal slots and the recorded thresholds. Separate the basic All Clear achievement from Crowned in Brass, which requires gold across the entire medal set.
Detailed Walkthrough
Blockade audit: prove both hard stops are gone
Objective: Create a two-item destruction check for the armored pillboxes and prevent the assault signal from becoming available in your plan until both checks are positive.
The mission is organized around a binary blockade, but the two emplacements must be tracked individually. AP is the recommended ammunition role for these armored positions. Start with two named status lines: untested, hit, or destroyed. Only destroyed closes a line. This matters because the failure rule is tied directly to signaling while either emplacement remains active; three premature horn uses end the mission. The disciplined sequence is therefore not simply “fire, then advance.” It is classify the first hard target, commit AP, inspect feedback, update one status, and perform the same confirmation on the other. The Río Mula valley identifies the setting but supplies no bearing, range, or order for the pair, so choose between them from the current battlefield state. The 12-charge allowance is tight enough that repeated shots with unclear results create pressure elsewhere. Preserve a clear count after each hard-target attempt and keep allies outside the decision by checking the intended impact area before firing.
Watch for
- Treating a visible hit on a pillbox as confirmed destruction.
- Sounding the horn after only one of the two blockade entries is closed.
- Using the location description as though it encoded an aiming solution.
Rail interception: read motion, impact, and survivors
Objective: Stop or destroy the inbound reinforcement train while preserving enough flexible ammunition to manage the state created by a derailment.
The train adds motion and branching consequences to the blockade task. It follows a timed straight-line approach, which means delay has operational cost, but the mission information does not provide a universal firing moment. Observe the current line, distinguish the train from the station and other town entries, and define the intended outcome before committing. A track hit can derail the train; derailment may release surviving reinforcements. That is not a failed interception, but it changes the problem from a moving rail target into exposed soft opposition. Maintain three fields in the note: train approaching, train stopped or destroyed, and survivors present or cleared. AP remains reserved for armored emplacements, while HE and HCHE cover soft targets and train survivors. Five rail cars are listed alongside infantry and mechanized elements, yet those counts do not prescribe shot allocation. Confirm the visible result, then choose ammunition for the resulting class rather than repeating the shell used in the preceding action by habit.
Watch for
- Assuming a derailed train means every reinforcement has been removed.
- Spending all flexible ammunition before learning whether survivors emerge.
- Confusing the Train Station roster entry with the moving interception objective.
Release check: make the horn a deliberate transition
Objective: Authorize the allied advance only after the blockade and rail checks agree that the approach can be opened safely.
The horn begins the allied assault. It should be handled as an irreversible transition point in the run, not as a way to ask whether the mission is ready. Before using it, read aloud or visually confirm four lines: pillbox one destroyed, pillbox two destroyed, train stopped or destroyed, and any immediate survivor problem understood. Then reconcile the displayed powder charges with the run note. The enemy roster also includes an Enemy Commander, an Enemy Hospital, infantry, armour, and mechanized units, but their presence does not replace the primary release test. Ally safety matters throughout because Measured Fire Star requires zero ally kills at gold. Once the horn sounds, observe whether the advance proceeds through the cleared approach. If it does not, return to the unresolved state rather than wasting another horn use; the explicit failure counter makes repeated guessing dangerous. The operation should feel like a gate opening after inspection, not a timer being hurried by repeated signals.
Watch for
- Using the horn to test whether an emplacement is actually dead.
- Letting town activity distract from the two confirmed blocker states.
- Failing to reconcile the charge count before initiating the advance.
After-action choice: clear, medals, and unlocks
Objective: Separate primary completion from optional cleanup, then evaluate whether the current run supports a safe medal push.
The main task is complete once the road is open enough for the allied column to move forward. Enemies still in town become optional at that point. That distinction allows a controlled stop: a completed operation need not be endangered merely to make the battlefield look empty. For a medal replay, however, the listed thresholds deserve deliberate preparation. Gold on Measured Fire Star allows no ally kills. Unrelenting Volley Medal asks for a longest kill streak of at least 20. Ordnance Efficiency Cross combines at least two enemy kills per shot with at least 10 enemy kills. Unaided Fire Distinction requires no reconnaissance and more than 18 enemy kills. These goals can pull the run in different directions, so inspect the actual result rather than assuming one clean sequence satisfies all four. Completion unlocks Position Report, EMERGENCY MOVE !, and the SMK Shell. “All Clear” marks completion; “Crowned in Brass” belongs only to an all-gold medal result.
Watch for
- Continuing optional cleanup without checking ally risk or remaining charges.
- Treating completion as proof that every medal reached gold.
- Reading unlocks as extra conditions that must be completed before the mission can end.
Mistakes to Avoid
- Sounding the war horn while either armored pillbox remains active.
- Counting a pillbox impact as destruction without confirming the state change.
- Ignoring the timed train while concentrating exclusively on the emplacements.
- Assuming derailment removes every soldier carried by the train.
- Using HE or HCHE against the armored blockers instead of preserving the AP role.
- Spending AP on soft survivors while an armored position remains unresolved.
- Treating all listed town enemies as mandatory after the approach is cleared.
- Chasing a kill streak near allied units and losing the zero-ally-kill medal.
- Using reconnaissance during a run intended for Unaided Fire Distinction.
- Conflating All Clear with the all-gold Crowned in Brass result.
Achievements
All Clear
The completion achievement is awarded for intercepting Iron Road. Confirm the operational clear after the blockade is removed and the allied advance can proceed; optional town cleanup is not the identity of this achievement.
Crowned in Brass
The all-gold achievement is tied to earning gold on every Iron Road medal. Review all four medal results, including ally safety, streak, efficiency, and unaided-fire requirements, instead of inferring it from completion.
