I did a mission which has a larger building than the one those screens. Inside the building there's a staircase leading upstairs, but the second floor is partly destroyed, so when you're looking at it sometimes the parts which are destroyed blend in with the first floor. There's also a roof, but it's a full flat roof (there were even civilians on it in the Terror mission!) and not a sloped one. So there are 3 full floors for the building (F1, F2, Roof) and it's impossible to see ANYTHING once you move the camera indoors. You can see outlines of civilians all over and it's impossible to tell which floor they are really on until you look really closely. Horrific.
