Destroying terrain

[low_bidder]

I hold down the shift key as I move my bulldozer into the hex I want to flatten. You can do walls as well.I think AT trenches too. Wire. Not sure if there are turn differences It has been a while so that might have changed.
Follow up units pay a MP penalty. A long time ago (last century) I found myself in a desperate situation. So I rubbled a row of buildings and used a flame thrower to set them on fire. My opponents were coming through but they seemed to have a lot of suppression. A shot or two and they retreated.
