Hmmm. In my limited experience, there've been a number of times LOS/LOF didn't correspond to the terrain. The most egregious example occurred when a railway embankment at higher elevation intervened between units at lower elevation, yet they were still able to direct fire on each other. Funny thing was, when I moved my unit onto the embankment (getting a little closer to gain advantage from the enemy's suppression), the LOS no longer existed! This situation may have been fixed with the v5.0 patch; unfortunately, I can't remember the scenario to check it out.
