Relatively recently joined German member of the board. A published author, his first debut being the WWII ISOT novel Wolf Hunt.
Hates badly researched WWII alternate histories, especially those which have endless and implausible Nazi wanks. He is known and respected on AH.com for his great reviews of the awful alternate WWII mockumentary made by Spike TV (reviewed in two parts on YouTube) and the thinly-veiled pro-Nazi AH novel Kaiserfront (reviewed on the AH Weekly Update blog).
You can find his personal site here. He also runs a blog about military history and assorted military fiction.
