It takes a 1:50,000 scale map distance of 1,800 meters just to reach the protractor's square edge to get a reading.Īnother self-help technique is to poke a hole in the center and place a knotted string in the center to overlap extend over your map lines for a reading, but this leaves a knot in the center, obscuring the center placement of the original point to be measured from and the string can fall out at the worst possible time. You lose the mills scale for artillery calls for fire and still have to draw extended lines on your map, cluttering and obscuring important details. Often hand trimming of the mils edge results in a sloppy, uneven edge cutting off degree marks. When measuring a grid angle from point A to point B on a map with the Army protractor, you are often forced to draw and extended line so you can reach the square's edge for a measurement! An improvement somewhat is to trim the mils scale off, but not a significant enough improvement. The RM protractor is round with degrees and mils scales on the outside edge. Army protractor (GTA 5-2-12) is a square shaped piece of clear plastic with mils scale and degrees on the outside edge of the square. Army SNCO, Rudy Madayag and offered in military clothing sales stores (MCSS) is far superior, easier to use and more accurate. The round and improved square map protractors produced by retired U.S. The current square issue map protractor ( GTA 5-2-12) is cumbersome to use, resulting in added time in planning, and inherently inaccurate resulting in map errors that can cause units to get lost and rounds to fall on friendly forces.
