This is an Extended Universe tank, this was not shown in halo but it does use halo tech. This is the first in a new line of Devastating tanks that instead of a 90mm tank gun, has a massive and devastating Onager mass driver cannon. The shell is powerful enough to blow loads of enemy infantry to the universe next door and escort tanks, structures and even massive crusiers personally to the gates of hell. The tank supports a more traditonal 2 tread system compared to the scorpion's 4 tread, for structural support. It also comes with 12ft nose mounted pikes for pushing through enenmy fortifications, tanks and line. Enjoy the tank.
