UNOFFICIAL GUIDE
IRON NEST Corrections: From Impact to the Next Shot
IRON NEST corrections become much easier when every line keeps its own origin. A correction begins at the previous impact, produces a corrected point, and then hands that point to a fresh firing line from the current Iron Nest. The correction arrow itself is not the gun bearing.
Quick answer
Start at the previous impact. Follow the reported correction distance and direction to mark the corrected point, then measure a new bearing and range from the current Iron Nest to that point. Recalculate whenever the point, firing origin, gun position or charge context has changed.

This answer applies directly when the game gives an explicit correction vector. A crater without that vector is a different evidence case: keep only the inputs that are still trustworthy, change one control at a time, and do not promote one successful adjustment into a universal rule.

Next firing input
A fresh bearing and range from the current Iron Nest to the corrected point, followed by a charge and elevation that belong to that shot. IN-GAME TEXT plus qualified firing-chain inference · build 24750322. The correction vector locates a point; it does not replace the Nest-to-point firing line.
The page uses three working input types. They are a guide to evidence, not official menu names or a complete list of every mission mechanic.
If you only have a report bearing or an incomplete location constraint, first return to the origin-first bearing handoff. If several independent constraints still need to locate the target, finish the triangulation firing-line handoff before treating any line as a shot solution.
Follow the correction workflow
Start at the previous impact.
1. Name the evidence and its origin
Write down what you actually received: an explicit vector, a crater, or a report that still needs interpretation. For the Mission 2 yellow annotation, the origin is the previous impact. Do not silently replace that origin with the turret, a Spotter or the target.
Done when: every distance and direction in your notes has a named starting point.
Common mistake: drawing a plausible-looking arrow from the Iron Nest because the final shot will also need a line from the Nest. Those are two different lines.
2. Establish the corrected point
With an explicit vector, move from the previous impact in the reported direction for the reported distance. That endpoint is the corrected point. Use the published tactical-map tools to record and measure the point; this guide does not duplicate every drawing control.
With crater-only observation, keep the crater as a reference and resist the urge to infer an exact vector the game did not provide. The corrected aim is still an operational judgment, not a hidden fixed delta recovered from the crater alone.
Done when: the next intended point is explicit in your notes and is not being confused with the old impact.
Common mistake: reversing the vector and walking from the target back toward the impact.
3. Choose rebuild or controlled adjustment
Rebuild the firing solution when the target point, firing origin, Iron Nest position, charge choice or shot context has changed. Rebuilding means getting the current Nest-to-point range and bearing again, then using values that belong together for the next shot.
A controlled single-variable adjustment is only defensible when the point of reference and the other controls are still reliable. Change one thing, observe one result, and keep the evidence attached to that shot.
Done when: you can say which inputs were rebuilt, which were retained and why each retained value still applies.
Common mistake: calling an old card “close enough” after the Iron Nest moved or the charge changed.
4. Transfer the next shot to its owners
Set the final firing bearing from the current Iron Nest to the corrected point. Send the current distance and charge decision to the Calculator when you need elevation or predicted airborne timing. Keep task targets, waypoint timing and completion signals with the relevant mission guide.
Done when: the next shot has one current origin, one target point and one internally consistent set of firing inputs.
Common mistake: treating the yellow arrow, an observation bearing and the turret bearing as interchangeable numbers.
Read the yellow correction from impact to target
Mission 2 gives the clearest build-backed definition. Its task text says the yellow number is the distance from the impact point to the target, and the yellow arrow is the direction from the impact point to the target. Read both from the same origin: the previous impact.
That instruction solves a location problem. It tells you where the corrected point lies relative to the miss. It does not directly tell the turret how far to rotate, because the turret is standing at a different origin. Once the point is marked, the final gun line starts at the current Iron Nest.
The full mission context—including STAR ammunition, repeated observation shots and its completion signal—belongs to the Fire and Light correction section. Do not carry its task-specific UI into missions that only show a crater or use another reporting method.

Rebuild the firing solution or adjust one control?
Use a conditional answer, not a slogan.
Rebuild when the geometry changed. A new corrected point, a different firing origin or a moved Iron Nest changes the line. Measure bearing and range again from the current position. A different charge also changes the elevation and timing context, even if the map point did not move.
Retain a value only when its dependency did not change. In a stable crater-reference problem, the known bearing, charge or another control may still be usable. Retaining that value lets you adjust one remaining control and observe the result. It does not make the entire old firing solution current.
Do not use miss size as a universal switch. This research found no build-backed half-kilometre threshold, fixed angle step or automatic bearing/elevation delta that decides between the two branches. The expensive failure is not “recalculating too much”; it is combining values that describe different points, origins or shots.
Correct from a crater when no vector is provided
A crater can still be useful when it is the only visible reference, but it does not come with the same facts as the Mission 2 yellow vector. Keep the variables you genuinely know, change one uncertain control, fire once, and compare the next impact with the same reference.
The The Gorge manual-fire section shows why this method matters when the calculation machine is unavailable. Its task sequence and one-run firing values stay on that mission page. This guide carries over only the qualified method: one observation per shot and one controlled change while the remaining inputs still apply.
If the target point changes, the Iron Nest moves, or the charge changes, return to a rebuild. Do not stack a crater adjustment on top of a stale origin and call the combined error a correction formula.
OBSERVED / REPORTED · mission-specific method, not a universal game equation.
Keep flight time separate from the correction
Predicted airborne time answers how long a shell is expected to be in flight under the current build model. A planned fire time answers when to fire for a chosen impact clock time. Target state at impact answers where a moving target is expected to be. These are related inputs, not the same quantity.
Use the Calculator’s six-solution timing tool for build-specific elevation, predicted airborne time and optional planned fire time. Its limits exclude preparation, loading, aiming, trigger, network, reaction and target movement. This page does not repeat the formulas or turn that estimate into a hit guarantee.
For a moving target, the mission still owns the route, waypoint, speed changes, turn behavior and success condition. Knowing airborne time alone does not supply a universal lead or intercept point.
How do you calculate rotation after a correction?
First decide which rotation you mean. The correction direction runs from the previous impact to the corrected point. The turret firing bearing runs from the current Iron Nest to that point. A moving target’s course or turn is a third quantity. There is no single naked “rotation” number that safely replaces all three.
For the gun, locate the corrected point and measure the current Nest-to-point bearing. Transfer that bearing to the turret through the normal firing workflow. Do not copy the yellow arrow as the turret setting unless both lines happen to agree in that particular geometry; coincidence is not the rule.
This page does not publish a fixed rotation delta. Report-origin questions belong to the bearing guide, map geometry belongs to Map and Triangulation, and target-course timing belongs to the relevant mission.
Troubleshoot a correction that still looks wrong
Work from origins and dependencies before changing more controls.
Check the origin. Did the correction start at the previous impact, or did you draw from the Nest or target by habit?
Check the direction. Does the arrow run impact → corrected point, or did you reverse it?
Check the point. Are you aiming at the corrected point, not the old target estimate or the last crater?
Check the firing origin. Has the Iron Nest moved since the bearing and range were measured?
Check the shot context. Did the charge, target, gun side or other recorded input change?
Check the handoff. Are correction direction, observation bearing and turret bearing being treated as separate lines?
Stop at the evidence boundary. The current research does not confirm how a correction marker chooses a target, what two yellow half-vectors encode, or how marker deletion and lifetime work.
When the first six checks are clean and the marker itself remains confusing, record the build, mission, before/after recon state and a clear capture. That can support a later evidence update; it should not be converted into a rule from one run.
Version and evidence limits
These limits apply to Version 1.0 (1622), Patch #5, build 24750322. Do not generalize Mission 2's explicit-vector interface to missions that do not show it, turn crater-only practice into a fixed delta, or treat current-build timing behavior as a promise for later releases.
The shared extraction does not expose a universal correction-bearing, correction-distance, elevation-delta or rotation-delta output on the 36 impact-trigger records reviewed. That absence limits what this site can publish; it does not prove the game has no internal correction logic.
Still unconfirmed: runtime target selection, the exact meaning of two yellow half-vectors, correction-marker deletion and duration, photo-update behavior, and a cross-mission target-lead model. A later build, direct developer explanation or repeatable current-build capture can reopen those items.
Fire correction FAQ
Where does an IRON NEST correction start?
For the explicit Mission 2 annotation, it starts at the previous impact. The yellow distance and direction both run from that impact toward the target or corrected point. Other missions without that annotation need their own evidence.
Is the yellow arrow my turret bearing?
No. The arrow describes impact → corrected point, while the turret bearing describes current Iron Nest → corrected point. Mark the point first, then measure the firing line from the current Nest.
Do I need to rebuild the whole shot card after a miss?
Rebuild when the point, origin, Iron Nest position, charge or shot context changed. If the geometry and other controls remain trustworthy in a crater-only observed-fire case, you may retain them and adjust one uncertain control. There is no universal yes-or-no rule based only on miss distance.
What should I do when there is only a crater?
Keep the crater as a reference, preserve only the inputs that still apply, change one uncertain control and observe the next shot. That is a qualified observed-fire method, not an exact vector or fixed correction table.
Can I reuse the old bearing after the Iron Nest moves?
No. The old bearing describes the line from the previous firing position. A known target point may remain useful, but the moved Iron Nest needs a fresh bearing and range to that point.
Does flight time give me the complete lead for a moving target?
No. Predicted airborne time is one input. It does not include the target route, speed changes, turn behavior, preparation or firing delays, so the relevant mission must supply the rest of the timing problem.
Are the two yellow half-vectors and marker lifetime confirmed?
Not by the current evidence. Their exact UI meaning, target selection, deletion and lifetime remain open items. This guide does not turn a community interpretation into a current-build rule.
