C.W. Richeson has given Grey Ranks a very good review over at rpg.net.
“…I have been very pleasantly surprised with how well done Grey Ranks is. It focuses on the journey of the characters and all the high emotions they face during this turbulent time in history. While the mood can certainly be dark, it can be joyous and everything else too. With everything I need right in front of me — from history to German phrases to game ideas — I can pick up Grey Ranks and run an exciting game at the drop of a hat. That makes this one a winner for me. If you like deep character focus, rules light mechanics, and narrowly structured games then pick this one up.”
