They are graduated marks used to estimate the range of an object. If you know the relative size of an object. The newer models are measured in mils because the are more accurate than degrees, Thre are 17.8 mils in a degree. The further the object is the smaller the object appears. If you know the estimated size of an object (a Tank), you can bracket it between the horizontal lines on the verticle post or the verticle lines on the horizontal post to determine its distance from you. The vertical lines on the horizontal base can also be used to estimate right to left distance. If you were calling in artillery, you would use the binos to adjust fire on the target by measuring from where the first round hit and calling back to the fire direction center to move right or left, say 100 mils and up 250 mils. Then fire for effect!

width over range in mills WORM. I was a gunner on a 106 reckless rifle. Later in a NATO excersice as punishment was a radio operator for a FO. The FO was a lt and some kind of math geek.He was explainig about artiley fire, and barrage points, if it wasn,t so cold and wet might have learned something.
