I believe the military unit is "mil" and that there are 6400 of them in a circle, making them very close to a thousandth of a radian, and allowing the mental use of the small angle approximation sin theta is about theta for small theta. Thus when firing a mortar round, it would be easy to calculate a small variation in azimuth based on estimated horizontal separation in (yds. meters, etc) if one knew the rangewhich is essential to set the elevation!
