I chose to render the box art with the rear skirt only option 'Hoth style' as I felt it helped differentiate them from the Assault and Support Valkir in appearance. This image also débuts the Eisenkern StuG, this version is the grav assist but there is also a tracked version for you tread heads. (More on that in another update).
I could not resist putting a crushed Mortis under the rubble pile, as the StuG's chose to take it down the easy way, by dropping a building on it ;)
Enjoy the pics!
