Yeah. In other words, it doesnt make a hole below ground level, it piles the hole up above ground level, but only visually. If you roll a tank or a plane through a crater, its like it isnt there physically. Yet it's visually disruptive enough that a Panzer can hide in one and all you can see is the top of his turret. The striated brown color of the blast crater blends in quite well with the standard panzer camo pattern. Even bombing buildings is sometimes difficult because a bomb crater will overlay the building, making it hard to see (and difficult to tell if it's up or not).
