How to you resolve movement over terrain less than Height X?
Ex: I want to move troopers onto a LOS-blocking terrain piece that is, let's say, 3 inches high. It's sides are near vertial but the height of the terrain does not warrant a climb check. Do I count the sides of the cliff as part of the movement? Or is movement only measured horizontally? Can't find anything in the rules or RRG but maybe I overlooked it.
