Mission 2 triangulation: plot the target, not the spotters

The mission gives you two observation positions and two bearings. The positions tell you where the lines begin; they are not two targets.

Quick answer

Place Spotter 1 and Spotter 2 at the reported coordinates. With the yellow pencil, draw each bearing from the matching spotter. Their intersection is the target. Only then draw the red measurement from the Iron Nest marker to that intersection; that final line supplies the gun's bearing and range.

Concept trainer / illustrative coordinates

Two origins. Two bearings. One target fix.

Target fix
12NESTTARGET
Spotter 1 line Spotter 2 line Nest-to-target firing line

The yellow lines answer where is the target? The red line answers where should the turret point?

Procedure

  1. Anchor each report to its source

    Spotter 1's bearing begins at Spotter 1. Spotter 2's bearing begins at Spotter 2. Drawing either line from the Nest changes the problem and creates a false solution.

  2. Extend both bearing lines

    Use the yellow pencil and rotate each line until its displayed bearing matches the report. Extend the lines far enough to cross.

  3. Mark the intersection

    Drop a target marker where the two forward lines meet. If a report gives distance instead of bearing, use the drafting compass for that clue; a line and circle may produce two possible points.

  4. Create the firing measurement

    Use the red pencil from the spike at the bottom of the Iron Nest marker to the target fix. Move this Nest-relative bearing and range to the ballistic calculator.

How to know it worked
  • Both observation lines begin at their named spotters.
  • The target marker sits at the forward intersection, not at a spotter coordinate.
  • The firing measurement begins at the Iron Nest and ends at the target.
If it does not work
The turret points away from the targetYou probably measured target → Nest or used a spotter bearing as the turret bearing. Redraw Nest → target.
The lines never meetCheck the starting tokens, line direction and matching spotter numbers. Nearly parallel reports may be rounded or ambiguous.
A line crosses a range circle twiceKeep both candidates. Use a third clue, recon, or mission context instead of inventing certainty.
Later orders reference a missing spotterKeep the numbered spotter tokens on the table even after clearing temporary pencil lines.
Evidence boundary

The central sequence is consistent across two independent Steam Community sources. We did not run Mission 2 ourselves, so examples on the interactive board are conceptual rather than captured mission coordinates.
