They are natural units – and dimensionless. A radian of angle is that which occurs when the arc length on a circle is equal to the radius of that circle. There are two pi radians in a circle. So 2 pi radians is equal to 360 degrees. As angles get small, the arc length of that angle starts to approach a straight line, perpendicualr to the radius. In shooting terms, it means the drop, or come up, etc. is the radian angle times the radius. Both the drop and the distance have to be in the same units. The radian angle is the angle in milliradians divided by 1000. Thus the distance (come up or drop) is the angle in mils times the distance divided by 1000.
