IRON NEST Marking Tools: Pencils, Bearings and Compass

Use IRON NEST tactical-map marking tools: draw bearing lines with colored pencils, measure range with the compass, and preserve useful spotter markers.

QUICK ANSWER

What you need to know

Community-tested Mission 2 guidance shows that yellow or red map pencils display bearing while you draw a line, and the compass is used for distance/range circles. Use those tools from the correct map origin instead of searching for a separate physical protractor.

Bearing lines

Start the line at the correct origin—often a spotter marker—and rotate it until the displayed bearing matches the report. Extend the line far enough to intersect a second measurement.

Range circles

When a report gives distance, use the compass from the report's origin and draw a circle at that range. Intersections with another bearing or range measurement produce candidate target locations.
