I didn't get this, but that map needs other fixes, in that:
1) The soldiers spawns partially inside the building, and, well, Murphy's law kicks in - either short-range soldiers will end up on the second floor or sniper or GL in the toilet... meaning you have to spend a round moving some to the start. Annoying.
2) One floor of the T-shaped building (left and below the left branch of "T", above the door from the area between the buildings) seems to be a floor without entrance other than some sort of busted makeshift elevator?
