The second booklet in Guidon Game’s Wargamer’s Guidebook Series came out around April 1972, and reprinted articles from The Avalon Hill General, International Wargamer, and Panzerfaust collected by Don Greenwood.
These are all about the original 1965 Avalon Hill release of the game, though there is also a review of Guidon Games’ variant Operation Greif.
