When playing Battlefield 3, I've noticed that unlike many other shooters, I can actually damage buildings and other forms of cover. This is an interesting game mechanic, but I'm curious about its limits.
Is there a maximum amount of damage that I can do to a given structure? Can I cause it to collapse completely? Are there only certain structures that can be damaged? Beyond just blindly firing explosive weapons into a building, how do I tell if I can or can't do (additional) damage to a building?
