I'm sure most of us all know of the beasts the Germans made artillery wise. As i have been digging around on the history of the units that manned these guns, I wonder if they had a "special' badge or tinnie that indicated they were part of this group? Does anyone have any relics from these crews or any pieces like a shell casing? I find alot of history on the guns themselves, but not the crews or its logistical feats to make them work. Perhaps someone knows of a good book that i need to read on this particular subject. I found this bad assed pic that has started my hunt for relics pertaining to these huge beasts.
