Pictures are up of the rumoured space marine command tanks - they're a warhammer world exclusive!
Rhino Primaris - comes with a load of comms gear on the top, decorative panels and doors to the sides and a twin linked plasma gun instead of storm bolter (by the looks of it)
Land Raider Excelsior - comms gear, a couple of banners, more decorative door panels etc, and a grav cannon with grav amp instead of the twin linked heavy bolter.
Both tanks appear to have new commander/gunner pieces
No indication of rules yet.
