Grid Reference Systems PDF (Master Navigator Series – Part Four)

Master the Language of the Map

Master Navigator Part 4: Grid Reference Systems unlocks the essential skill of precision navigation using grid coordinates. This fourth guide in the 10-part digital series by Joshua Enyart, the Gray Bearded Green Beret, focuses on teaching you how to locate any point on a topographic map using grid systems like UTM and MGRS.

Whether you're calling in a rescue location, planning a route, or finding your exact position in rugged terrain, understanding how to read and plot grid coordinates is non-negotiable. This guide breaks down what grid references are, how to read them accurately, and how to communicate them clearly—especially when lives depend on it.

Train with Real-World Application

Joshua Enyart draws on decades of Special Operations experience to demystify one of the most critical elements of land navigation: coordinate systems. You’ll learn how to use a coordinate scale (protractor), interpret different digit grids (4, 6, 8, and 10-digit), and follow the golden rule of grid reading: “Right, then Up.”

By the end of this guide, you’ll confidently understand the differences between UTM and MGRS, and you’ll be able to plot precise locations on your map—even in complete wilderness.
