The Doomwheel does D6+1 Impact Hits. In the case of a Doomwheel hitting a friendly unit, resolve Impact Hits immediately after contact and then move the Doomwheel back an inch. In close combat, the Doomwheel uses the Attack profile for the crew. It has Random Attacks (2D6), rolled separately for each round of combat. The Doomwheel itself does a Grind Attack at the beginning of each round of combat in which it did not charge. A Grind Attack does D3 automatic S6 hits against one enemy unit in base contact, distributed as per shooting.
