units range over walls

I made a great keep in one of my campaign's maps. I made the battlements of its walls using cliffs, like "raise two", "raise one", "raise two", "raise one" to look like battlements and so...

But the problem is that the ****ing archers just can't see enemies and fire through the walls, even the lower ones (those which would be the gaps between the battlements). The question is: is there a way to make units see through the lower walls, at least? Please, say there is!

try using the "low wall" doodad instead of cliffs, its looks just as cool.

Hmmm, maybe, but it doesnt look as cool...

Maybe I should use just 1 level cliff to make the battlements... damn... There must be a way...

take the small wall end model, jack its selection scale up to 3-5 ( dpening on size of keep) and use a flat surface to put them on. put a pthing blocker under it so they cant walk thorugh, and they will still be able to see past it, because the pathing size is much smaller

give vision with triggers to the other side where the archers are shooting? then they can see already? how about that

Try creating a visibilty modifier outside the wall.
