This tool is equivalent to the Graphic Training Aid 5-2-12 Coordinate and Protractor used by the United States and NATO military forces around the world. However, this tool offers significant benefits over the standard issue GTA 5-2-12. This tool is printed on 30 mil plastic stock with a protective coating. This makes it about the thickness and stiffness of a credit card. It's 33% thicker than the standard military issue version, so it's less likely to be bent or broken when you need to use it. It also has rounded corners to keep it from wearing holes in your pockets. It offers Scales: 1:25,000 x 1km/1:250,000 x 10km, 1:50,000 x 1km/1:500,000 x 10km, 1:10,000 x 100m/1:100,000 x 1km.
