If sighting in at more than 125 yards, with a laser bore sight system the user can determine the exact line of the bore to a target at a selected distance, measure down the drop distance derived form the ammo ballistics chart, and the resultant point will be the point to air the sight.
The goal is to ensure that the sights of the gun have the same lateral orientation as the barrel.
The root of the elevation problem is that the gun sight is mounted above and away from the barrel.

An optical gun sight system for an M1A2 Abrams Main Battle Tank supported in a lower housing which may be attached to the fixed internal upper housing in the turret of the tank.
A new gun sight system is required to mount within the internal housing and within the dimensional restrictions imposed by the interior of the tank's turret.
Also, the sighting system is a very complicated and sophisticated instrument which must be carefully aligned with the tank's turret and thereby the main gun mounted to the turret.
