Grizzly tank got a new model and C&C Renegade-2 style camo.
Rino just got some new details, to look like related to older Mammoth tanks. I got idea that both Apocalypse and Rhino tanks based on Mammoth tank from RA1, while Apocalypse is direct successor and Rhino is more cheaper version for MBT role.
Reminds me of a Panther Tank or Tiger II, nicely made tho!
