IRON NEST Map Coordinates and Triangulation Guide

This IRON NEST map coordinates and triangulation guide covers grid references, spotter lines, target intersections, markers, range, and bearing.

Coordinates describe a point, not a firing solution

The map uses lettered and numbered grid squares with finer sub-grid coordinates. Plot the position inside the named square before drawing bearings or distances. A correct grid with the point placed on the wrong edge can create a large error downrange.

Orders and spotter reports may identify friendly observers, reference points, bearings, and distances. Use those facts to locate the target; only afterward should you measure from the Iron Nest to create the gun’s range and bearing.

A repeatable plotting order

  1. Mark the Nest and every known friendly or reference position.
  2. Label each report so information from different spotters is not mixed.
  3. Project each stated bearing from the observer that supplied it.
  4. Draw any stated range from its correct center.
  5. Place the target where the independent lines or arcs best intersect.
  6. Draw the final firing measurement from the Nest, not from a spotter.

The community guide describes the red pencil as the tool that records the firing range and bearing, while other marking tools help with construction and notes. Treat colors and interface behavior as current-build guidance that may be revised.

Account for imperfect intelligence

Spotter information can contain uncertainty. A close intersection is not always an exact reveal. Reconnaissance or an observing round can provide stronger confirmation when the mission and resources allow it. Keep friendlies and expected effect radius visible before selecting ammunition.

Version note

The official workflow and community map details were reviewed for version 1.0 (1663) on September 2, 2026. Exact plotting conventions are marked mixed because objectives and reports can be procedurally varied.
