This military triangle scale protractor is a great addition to any military or Bug Out Bag. You can tie a piece of paracord or other string in the center hole to use for accurate measurements with the mil, degree, or back azimuth scales. First, locate the grid square in which the point (for example, Point A, Figure 5-21, page 5-24) is located (the point should already be plotted on.

ACCURATELY CUT - What sets this protractor apart from most are the accurately cut triangles, giving you increased accuracy during land navigation. Protractors have a vertex mark at their base mid-point from which you can measure all angular directions. It is marked in degrees (the inner scale) and Military Mils (the outer scale) around the outside. Its scale, graduated in angular units or degrees, fringes the instrument’s upper-edge. Measuring 5” X 5”, the Army map protractor can be used with a variety of metric-based coordinate systems, including MGRS, UTM, and USNG. The scale has three die cut triangles for access to mark the map being measured. A protractor is a mathematical instrument used for measuring, drawing or plotting angles. Rothco’s Coordinate Scale Protractor will accurately show your coordinates and endpoint when used with a scaled map.
