Our factory walls are flimsy ... Think of a warehouse in this instance
If they are required to be more than flimsy they are stone or brick.
i think Tin sheet might be the closest match along the lines of a nissen hut.
Be realistic Andrew, this kind of building did not exist in 1944 Europe. Certainly not in rural Belgium. Pressed tin buildings were rare at best even in the U.S. at this time.
My main point is that you only have one designation for "factory wall". So, assuming that all factories that are present in the WaR maps use the "factory wall" coding, then they all have "flimsy" walls and can be seen through in such a manner. This, I think, is completely misleading. When I think of a factory in 1944 Europe, I think of Brick buildings with smoke stacks etc. Even warehouses would have been made of wood at the very least and should be coded as such.
