I found this site in a link on an old RPG.net thread. Since I am a big fan of the DG setting (I am probably going to have to get some book covers for my copies...since it doesn't look like there is ever going to be a new edition) I am always looking for new material that could be used. While I doubt that I would run a WWII era DG campaign this still has information which could be useful as backstory.
