The Tweel's bigger (military driven) cousin

Very cool upgrade to the Tweel, but not quite the same.
Me want honeycomb! lol

Edit: The only improvement I would make is to add a plate to cover the outside of the honeycomb. Maybe one exist already & it was removed just to show the honeycomb, but if one doesn't, to give a worst case scenario, the chamber of that honeycomb shape looks a perfect size to put a "pineapple grenade" in there.
That wouldn't be good. :ahh:
