How to Triangulate
Triangulation in IRON NEST is a map problem: two pieces of information shrink where the target can be. The firing solution is a second measurement, always taken from the Iron Nest itself.
Field Method
Safe core sequence
- 01
Mark the Iron Nest and every Spotter you can identify on the tactical map.
- 02
From Spotter 1, draw the reported bearing as a line. Spotter bearings originate at the Spotter, not at the gun.
- 03
From Spotter 2 (or a distance arc / compass if you only have one bearing plus range), add the second piece of geometry.
- 04
Treat the intersection (or the remaining short segment) as a candidate target location — not yet a firing solution.
- 05
From the Iron Nest’s current position, re-measure the firing bearing and range to that candidate.
- 06
Only then take those numbers to the Ballistic Calculator. Recalculate if the Nest moves or the report changes.
Cross-checked — A Steam player guide and a third-party map guide both describe the same principle: plot known points, draw bearing lines (and distance when you have it), then read the final firing bearing and range from the Iron Nest. That overlap is why this sequence is published.
Not published here — Grid letters, sub-cell counts, line colors, compass clicks, and any example coordinates from videos are version- and mission-specific. They are not written as fixed answers.
Common failure
Using a Spotter bearing as if it were already the gun bearing. Community walkthroughs of Fire and Light show shots going wrong when the firing line is generated from the wrong origin. Locate from the Spotter; shoot from the Nest.
