Physically, it looks like an oversized tank - while Grizzlies of this period tended to have a very low profile, allowing greater protection, Prism tanks have smooth chassis reminiscent of those of armored personnel carriers, including the IFV. The weapon and power systems take up most of the extra space this chassis design provides. The weapon itself has an extreme range (though not as extensive as that provided by V3s and Dreadnought missiles, but missiles fired by those can be shot down) and tendency to have a dispersed beam - basically the beam diffracts off of targets, causing secondary beams that fly out in all directions, but with an extremely short range. Particularly in the case of highly seasoned Prism Tanks, these secondary beams can be extremely powerful.
