There was nothing like setting up a textbook ambush, and then having your inexperienced gunner on an MG42 panic and run off when you gave the order to fire...
I think the map was even "deformable" in that if you ordered a tank to move somewhere it could break down walls and such to get there, walls that soldiers could have used as cover while moving around etc.
Note though that the graphics was top down 2D, so it was "cheap" to replace a standing wall tile with a broken one.
It's getting hard to run on current machines, though, with its hard-coded screen sizes and a scroll speed that's unusably fast.
The tanks definitely felt underwhelming sometimes, but overwhelming other times. It depended a lot on the environment, the type of tank, and the enemy units, which seems pretty realistic. It was interesting and terrifying how invulnerable some of the better German tanks could be.
