See Codings Artillery Computer, a mod which, among other things, provides the angle added by the ground's slope, so that you can apply that offset. (Except that it gives it in degrees, making it pretty useless for me).\r\n Ideally of course, the mortar sight would just give you the _actual_ azimuth and elevation of the barrel, relative to the coordinate system, not relative to the piece of terrain you happen to be set up on."}}
