Low or comparably flimsy obstacles such as walls, hedges, light woods, shacks, privies and piles of rubble have little chance of impeding an Iron Daemon, and all such obstacles (up to the height of the Iron Daemon's wheels) are ignored for movement and combat by the Iron Daemon. Furthermore, if a suitably sized chunk of this type of terrain can be removed from the battlefield after the Iron Daemon crashes through it, do so!

All forms of marsh and water terrain however are still treated as impassable by the Iron Daemon.
