UNOFFICIAL GUIDE
IRON NEST Final Harvest Walkthrough
This unofficial IRON NEST Final Harvest walkthrough turns Mission 14 into a manageable sequence: read the train schedule before firing, use the waiting window to prepare targets, control counter-battery pressure through the FDCs, answer only the support calls you choose to accept, and recognise the 15-enemy primary-completion signal. It separates build-backed rules from player-reported tactics so a useful route never masquerades as the only route.
How to beat IRON NEST Final Harvest
Destroy at least 15 enemies, then wait for the primary-objective-complete and stand-down messages. Plan for the reinforcement train first, fire deliberately because the first landed shell starts counter-battery, and use an FDC pause to organise later shots and any support calls you accept.
The train, AA battery and fire-support requests can matter to the operation, but the reviewed build does not make all of them a single mandatory checklist.
Likewise, enemy icons may remain after the primary objective completes.
Let the objective state—not a full-map clear—tell you when the required work is done.

Evidence: IN-GAME TEXT — Campaign order, localisation, mission graph conditions and entity fields from build 24750322.
The completion check counts destroyed entities through an enemy filter; it is not a promise that every visible enemy type behaves identically in every version. The reliable player-facing signal is the combination of at least 15 destroyed enemies, primary objective completion and the stand-down message. Final Harvest follows the earlier Campaign operations in the complete IRON NEST mission list. That hub owns the wider order; this page stays focused on Mission 14.
IRON NEST Final Harvest walkthrough
The mission asks you to manage several clocks without turning them into one rigid order. A train moves toward the battlefield, the first landed shell starts counter-battery pressure, FDC destruction can create a pause, and optional support traffic can add short deadlines. The route below prioritises preparation and clear state checks.
1. Read the briefing before firing
Open with the schedule and intelligence, not a ranging shot. Identify the reinforcement train's route and timing, note Alpha and the reported FDC and AA information, and leave space to track support traffic. Record only values shown in the current operation.
A grid or flight time from somebody else's run is not a shortcut. Your gun position, current target state and ammunition determine the live solution. The useful transferable lesson is to collect the inputs before the first shell lands.
Success signal: You can state which moving or fixed target you plan to address first and which current-run inputs are still missing.
If not: Re-read the briefing and train schedule. Do not start the counter-battery sequence merely to reveal information you can obtain before firing.
2. Plan the moving-train opportunity
Choose a waypoint you can identify reliably, then work backward from when the train is expected there. Calculate range and shell flight time with the current operation's data, and decide whether your crew can complete the shot before that opportunity closes.
Treat train-first as a strategy, not a completion rule. If the timing is too uncertain, wait for a later readable point or prepare to engage the reinforced position after arrival. The mission graph supports both an in-transit interception branch and an arrival branch.
Success signal: You have a current-run intercept plan or an explicit after-arrival fallback, without depending on a copied firing solution.
If not: Stop refining an unreliable shot and preserve attention for the FDCs and primary enemy count.
3. Use the waiting window to pre-plot priorities
Before the first round, organise likely fixed targets and decide what each gun or crew member will handle. FDCs are the key counter-battery control targets. The AA battery is optional, and other enemy positions can contribute to the destroyed-enemy count, so build a queue that can change after each report.
This is also the time to prepare shell choices for possible support requests. Do not assume that a request has arrived or that it must be accepted. Preparation reduces the time between accepting a call and executing its stated sequence.
Success signal: FDCs and other priorities are labelled, and you can change targets without confusing old and new calculations.
If not: Simplify the queue. One clear current solution is better than several stale ones.
4. Start counter-battery deliberately
The first player shell that lands triggers the counter-battery sequence. In the reviewed build, the message estimates about 10 minutes. Treat that number as build-specific context and immediately confirm that the timer state has changed.
Your first shot should therefore advance the operation. A deliberate train attempt, FDC strike or other priority engagement is easier to justify than a casual ranging round that consumes the quiet opening.
Success signal: The first shell lands on the intended task and the counter-battery state becomes active.
If not: Do not compound the miss with hurried fire. Recalculate from the current range and target state.
5. Destroy an FDC to create breathing room
When an FDC is destroyed, the mission graph pauses the counter-battery timer. Use the pause to reassess the train, calculate the next target and organise support work. The graph also contains a later shell-landed path that can unpause the timer, so the pause is a planning window rather than a permanent shutdown.
If more than one FDC remains, keep its position in the target queue. The exact timing interactions beyond the documented pause and unpause paths are not quantified here.
Success signal: The game reports the FDC result and the counter-battery timer enters a paused state.
If not: Check whether the target was actually destroyed and whether a later shell has already landed. Avoid assuming the interface is wrong before checking the event sequence.
6. Run the train, timer and support queues in parallel
Compare the next train opportunity, the active or paused counter-battery state, and any support-call deadline. You do not need to accept every allied request. If you do respond, follow the current message's target, ammunition, order and deadline exactly.
Keep each queue visibly separate. A train intercept calculation should not be reused for a fixed target, and an optional support shot should not erase your plan for the enemy count. If a support request would destabilise the primary route, declining it is consistent with the briefing's discretionary language.
Success signal: Each live task has a target, a current calculation and a clear next action; expired requests are removed from the queue.
If not: Return to the primary objective, secure the counter-battery window you can control, and accept fewer parallel tasks.
7. Recognise primary completion
The reviewed mission graph completes the primary objective when the enemy-filter destroyed count reaches at least 15. After reaching that threshold, wait for the primary-complete and stand-down messages. Do not infer failure merely because enemy icons, the train, an AA battery or an unanswered support request remain.
The threshold is the documented rule; the messages are the practical confirmation that the current game state registered it. If the count appears sufficient but the objective has not advanced, review which targets were destroyed and whether the current message queue has finished updating.
Success signal: The primary objective completes and High Command permits stand-down.
If not: Continue with verified enemy targets and re-check the current objective state instead of attempting an indiscriminate full-map clear.
8. Choose whether to continue firing
Once stand-down is authorised, continued fire is optional. That choice belongs to the game's ending boundary, not to the required Final Harvest clear. If you want to understand what further fire may affect, pause here and use the dedicated endings reference before acting.
Success signal: You can separate “mission complete” from the optional decision that follows it.
If not: Treat the stand-down authorisation as the end of this walkthrough and avoid presenting any later outcome as a requirement for completing Mission 14.
How to use the reinforcement-train schedule
Read the schedule as a set of moving opportunities. Pick a waypoint, note when the train is expected there, calculate the shell's flight time from your current gun state, and fire early enough for impact at the chosen point. If the current inputs do not support a confident shot, use a later waypoint or switch to the after-arrival branch.
Destroying the train in transit can reduce later pressure, which makes it a strong opening priority for many players. It is still not the only valid route. The build explicitly handles arrival by reinforcing the enemy line, allowing the operation to continue rather than declaring an automatic failure.
Do not publish or memorise a universal grid, bearing, range, charge, elevation or lead. Those numbers depend on the current operation. The reusable method is schedule → chosen waypoint → current range and flight time → fire time → result update.
Counter-battery and FDC timing
The dependable state sequence is straightforward:
A first player shell lands and starts the counter-battery timer.
Destroying an FDC pauses the timer.
A later player shell landing can unpause the timer.
In-game text in build 24750322 estimates about 10 minutes when the sequence starts. This page does not convert that estimate into a timeless promise, and it does not quantify an additional-time event whose player-facing amount was not resolved in the audit.
Use an FDC pause to do real work: rebuild a train solution, prepare the next target, review support traffic or correct a stale calculation. Before firing again, assume that a landed round can resume counter-battery pressure. That mindset prevents the common mistake of treating FDC destruction as a permanent safety switch.
How allied fire-support calls work
The briefing makes responses discretionary. You may decline a request; accepting one means following the current transmission rather than improvising a substitute. The reviewed mission text contains three response patterns:
An HE request calls for high explosive on the stated target.
A TEAR-then-HE request requires the obscuring round first and HE after it, not both at once.
A SMK request calls for smoke at the transmitted location.
Each accepted request can carry its own deadline. Read the message again before firing, keep the support target separate from your primary queue, and retire the task after success, expiry or a decision to decline it. Missing an optional call does not by itself redefine the primary completion condition.
For terminology and cross-mission ammunition records, use the complete shell-types reference. This walkthrough owns only the sequence communicated inside Final Harvest.

You choose whether to answer; if accepted, follow the stated shell, order and deadline.
Every enemy icon
Not required by the reviewed completion check
Remaining contacts do not override primary completion and stand-down.
Continued fire
Optional after stand-down
It belongs to a later choice, not the required Mission 14 clear.

Final Harvest tips for a cleaner run
These IRON NEST Final Harvest tips are planning aids, not a hidden mandatory route.
Protect the quiet opening. Read the train schedule and pre-plot the FDCs before any round lands, because first impact starts the counter-battery sequence.
Keep a train fallback. Decide in advance whether you will wait for another waypoint or fight the reinforcements after arrival if the first intercept becomes unreliable.
Spend each FDC pause. Use it to calculate, sort support calls or repair the target queue; expect later shell impact to resume pressure.
Separate live calculations. Label each target and retire stale values after a result. Current range and flight time belong to that shot, not the mission forever.
Accept fewer support calls when overloaded. The briefing permits discretion. A clean primary route is more valuable than an optional queue you cannot execute accurately.
Watch the objective state at 15. Give the mission time to register primary completion and stand-down instead of assuming every remaining icon must be destroyed.
Use evidence labels. Build text can define the state machine; a reported player route can suggest an order, but it cannot make that order compulsory.
Final Harvest troubleshooting
The counter-battery timer did not stay paused
Check the event order. FDC destruction pauses the timer, but a later player shell landing can unpause it. Confirm that the FDC was destroyed, then check whether another round landed after the pause before treating the state as unexpected.
The reinforcement train reached the battlefield
Continue the operation. Arrival reinforces the enemy line but is not documented as an automatic mission failure. Update the target queue, use FDC pauses to manage pressure, and keep working toward the 15-enemy primary threshold.
A support call did not register
Re-read the current transmission. Confirm the target, requested shell, sequence and deadline. For a TEAR-then-HE request, check that the obscuring round came first. If the message has expired, return to the primary objective rather than repeating an old solution.
Field reports or fire-detection targets look wrong
Community questions show that players encounter confusing report or detection states, but this audit does not establish a confirmed current bug. Check the current transmission, target, shell order, timer and completion state. If a low-risk retry is needed, preserve the version and steps first; no workaround here is guaranteed.
The destroyed count looks high enough but the mission has not ended
Wait for the current messages to settle, then verify that the destroyed targets belong to the enemy-filter count used by the objective. Continue against verified enemy targets if needed. Do not substitute an assumed full-map-clear rule for the missing primary-complete signal.
This page does not assign a mission-specific medal threshold to Final Harvest. The maintained medals by mission index owns the site's verified medal coverage and its evidence boundaries.
After primary completion and stand-down, further fire is optional. The White Shells ending boundary explains that later choice without turning it into a requirement for beating Final Harvest. Check that reference before continuing if the outcome matters to your run.
Final Harvest FAQ
What are the requirements to complete Final Harvest?
Destroy at least 15 enemies under the mission's enemy filter, then wait for primary objective completion and permission to stand down. The reviewed build does not require one fixed checklist containing the train, AA battery, every support call and every enemy icon. IN-GAME TEXT — build `24750322`.
Does destroying every FDC permanently stop counter-battery fire?
No permanent shutdown is established. Destroying an FDC pauses the counter-battery timer, while a later player shell landing can unpause it. Use the pause as a planning window and expect the state to change when you fire again. IN-GAME TEXT — build `24750322`.
Do I have to destroy the reinforcement train before it arrives?
No. Intercepting the train can reduce pressure, but the graph also supports an arrival branch that reinforces the enemy line and lets the operation continue. Prepare an after-arrival plan if the moving shot is not reliable. IN-GAME TEXT — build `24750322`.
Is the AA battery required for mission completion?
The current mission data marks the AA battery as an OptionalTarget. Destroy it if it helps your route, but do not treat it as a separate universal prerequisite for the primary completion check. IN-GAME TEXT — build `24750322`.
Are allied fire-support calls mandatory?
No. The briefing makes responses discretionary. If you accept a call, follow its transmitted shell, order and deadline; declining or missing one does not by itself replace the 15-enemy primary condition. IN-GAME TEXT — build `24750322`.
What should I check when field reports or fire-detection targets look wrong?
Check the latest transmission, target, requested shell or sequence, counter-battery state and primary-completion state. Confusing cases are community-reported, not confirmed here as a current bug, and no retry sequence is guaranteed. REPORTED — unresolved community questions.
When can I stand down if enemy icons remain?
Stand down when the enemy-filter destroyed count has reached at least 15, the primary objective completes and the game gives permission. Remaining icons do not create a documented full-clear requirement after those signals. IN-GAME TEXT — build `24750322`.
Which shells should I use in Final Harvest?
Follow any accepted support call's exact request: HE, TEAR before HE, or SMK as transmitted. For other targets, calculate from the current target and operation; the audit does not establish AP, HCHE or another shell as the uniquely correct choice. IN-GAME TEXT + evidence boundary.
