I experimented with this "just to see" what would happen 

:
Panzer vs. the troop tent...the troop tent won.  I imagine that a multi-ton, armoured, tracked vehicle should be able to run over a tent without much difficulty.  I'm sure this is a collision model type thing, and fixing it would require dividing ground objects into things than can, and things that can't, be smooshed by a tank.  Just an observation 

.
Otherwise, Great work!
Salute,
