Although the field obstacles were shrubs, I could imagine that the block-layout of the shrubs could easily be buildings in a town or city, as they impose the same constraints. If you're lucky and the shrubs are thin enough you could actually shoot through the corner. The height of the shrubs also afford some camouflage, and hide the exact location or turret orientation of tanks from the opponents. It allows for ambush and flanking movements like that.
Once contact is made, the outcome of the battle is usually decided very quickly. I like it!
