It is hard to explain to guys that high angle shooting is difficult to replicate on a normal post range and on most military posts. The angle and and range combo is hard to do. The next thing to watch is that the human eye sees in height more than width. That is the reason that an 'E-type' does NOT look twice as tall as wide, it looks almost three times as tall. This also makes "eyeballing" an angle a very bad idea. I have had guys, both students and instructors, estimate an angle in degrees; ie, more or less than X degrees. They always grossly over estimate the angle. A measureing device is needed but not attached to the rifle. And most shots are well within the point blank zero in an urban environment.
Now get onto a water tower that is 15 to 20 stories high and look out about 600 meters and you may need an adjustment.
