Bit of an odd question I guess!
I just picked up one of the battle fortress models go, and its got 4 gun turrets; two with a round piece to attack to the model, and 2 on squarish stands.
I just can't seem to find any place on the model where these things would logically go!
I guess the round turrets might fit on top of the turrets already on the front of the model, but that looks a bit odd.
Looking at the picture of the model on the GW page, I can't really spot the extra turrets at all.

Do these have a place to go? Are they stray bits for customizing your fortress in an appropriately orky way? Help!
