Bombed a country's City this morning, and again offline to double check things. I used 250 lb bombs. Offline, I could see the damage quite plainly where each single salvo of 3 bombs took out a block.
However, when I dropped on the black warehouses, no damage was recorded; and offline, I could see no signs of damage.
Who is in the know about the black warehouses? Is their hardness greater than the buildings and comprise a normal city block?
