I really don't understand what another heavy armor division is going to achieve at this point. I don't think we are being beaten back by the power of a superior Iraqi battlefield force.
If we wanted to level Baghdad, we could have done that the first night. This is a more subtle and specialized mission.
Maybe some folks are hoping Rommel and his full Panzer Afrika brigade will emerge from the nether-mist and we can line our M-1s up and get into a good ole slobberknocker.
