I do plan on adding two Rhino's in time but I'm happy with the army as it stands now and I think it'll give most other 3000pt sized forces a bloody nose on the tabletop as well. Now to get my paint on!
Legion Praetor leading a squad of Cataphractii armoured Terminators
Death Guard Legion Tactical Support Squad
Legion Heavy Support Squad with Multimeltas
Spartan Assault Tank
Incidentally the Spartan does have sponsons, I've just left them separate for ease of painting.
