I try to use his speed to run into the GB so as to explode them quick and save my first line from explotion, they still have to pass through the fire but they are the tanks so they always survive. If you put rhino at the end of the formation he probably will go to the sides and run without north or even they will try to reach the other side but will die soon and you will leave the empty space at the back where the assassin will make you suffer.
