How to Triangulate in Iron Nest: Spotter Bearing Guide | Iron Nest

The Fundamental Triangulation Rule

In IRON NEST: Heavy Turret Simulator, spatial geometry is your greatest weapon. More than 80% of missed shots stem from a single fundamental misconception: the Spotter Bearing Fallacy.

The Spotter Bearing Fallacy Explained

When Forward Observer 1 sends a teleprinter dispatch:

Spotter 1 Report: Hostile heavy mortar spotted at bearing 096°.

Many new operators immediately rotate their turret wheel to 096° and fire. This will result in a catastrophic miss.

• Spotter 1’s bearing (096°) begins at Spotter 1’s observation post.
• Iron Nest’s turret bearing must begin at Iron Nest.

Unless Iron Nest and Spotter 1 occupy the exact same physical coordinates, their bearings to the same enemy target can never be identical.

Two-Spotter Cross-Bearing Technique

When command provides reports from two forward spotters:

1. Spotter Alpha: Reports bearing $\theta_1 = 096^\circ$. Draw a straight ray extending from Spotter Alpha’s map icon along heading $096^\circ$.
2. Spotter Bravo: Reports bearing $\theta_2 = 053^\circ$. Draw a straight ray extending from Spotter Bravo’s map icon along heading $053^\circ$.
3. Target Intersection: The exact point where ray Alpha and ray Bravo cross is the confirmed enemy location.
4. Final Firing Vector: Draw a line starting from the bottom spike of Iron Nest to the Target Intersection.
   • Read the line’s angle for your Turret Bearing ($65.7^\circ$).
   • Read the line’s length for your Target Range ($12.91\text{ km}$).

Advanced Chained Reference Points

In late-campaign missions like Mission 8 (Rock of Gibraltar) and Mission 10 (Phantom Battery), intelligence is delivered as a chained sequence: $\text{Reference Point A} \xrightarrow{\text{Bearing/Distance}} \text{Waypoint B} \xrightarrow{\text{Offset}} \text{Target}$

Always trace each link from its respective origin. Only the final vector originates from Iron Nest.
