This Military Protractor is a measuring instrument, made of thin transparent plastic.
Protractor has a ruler for maps in 1:50,000 and 1:250,000 scale.
Angles can be measured in both miliradians (6400 mils) and degrees (360).
Protractor can be bent and is resistant to weather conditions.
The scales allow you to immediately have a visual comparison of the distance.
For example by measuring a distance of 10 with the coordinate meter on the scale 1: 50,000, you will immediately know that the distance is 1 kilometer. By plotting the route to follow, it will be easy to establish the distance to cover.
Furthermore, in the case of UTM coordinates, with the coordinate-meter it is possible to easily trace the point by measuring the distance from the merdian and parallel, in the reference scale of the map
