edit: i'm looking at that screen again and that panzer. why would there be a static of a brand new, undamaged tank just sitting in the road with infantry around it? looks pretty drivable to me
If its a static mesh now that doesn't have to mean that it won't end up as a drivable model in the future. Aka it could be posed there for a screen shot, and basically the animations and code etc might not be done yet. Then saying that it is a static mesh would be speaking the truth.
