WT-626G Marder MK II
Gunhead in an alternate future. The Germans developed the WWII version of their self-propelled anti-tank guns. Also known as tank hunters, their future counterparts retained the same role in the infantry division, and retained some characteristics of the original Marder, like the open topped compartment for the crew. Instead of being operated by 2 men however, the MK IIs needed only one pilot.
And yes this MOC still contains the cockpit design of the original Gunhead!
