In the US military (land forces at least) a recruit is trained for land nav
using compasses/optics that are graduated in degrees and mils.
In the US equipment there are 6400 mils to 360 degrees. And on long range
optics (rifle scopes, arty optics etc) there are markings on the horizontal
and vertical stadia for range finding. These markings (round dots) are 1 mil
in diam. Because 1 mil subtends a certain area at certain ranges these
optics give good results in range finding.
I had a Russian (Soviet actually) compass a few years ago. It, as you
stated, was marked in 6,000 units instead of the 6,400 units I was used to
using. It was confusing as I always had to think about the difference when
using it instead of just using the equipment. I got rid of the Soviet
compass. Not because of inferior quality of the compass but I am comfortable
using 6400 mils to a circle.
