Good point. AND, those guys can still get a hit on the other side of the ridge so there's not so much rushing involved. Call it in, fire for effect. (Now I think I'm confusing artillery lingo with mortar man speak).I dunno, the Abrams is still largely targeting a point target, which increases the likelihood of a miss.
I think you’re better served with a well trained 120mm mortar crew, so you can just blanket the entire hillside.
