Wyches assaulted a Battle Wagon and did not cause any damage to the vehicle. On the Ork players turn, can the battle wagon pivot, or must it move straight or not at all? If it can pivot, how will enemy models be moved? On page 68, under Tank Shock!, it says, "Not that because pivoting on the spot does not count as moving, this is not enough for a tank shock."
During the game, we decided that the battle wagon could not pivot, and it simply moved forward. We have a tournament coming up in two weeks, and this is something that could potentially happen. Any feedback at all would be appreciated!
