My friend Eric Morgensen has a list of FSSF books, video's etc. available on his website.

This includes, obviously a little known book, written by me which explains everything on the Force without the myth and BS attached, "Snow Plough and the Jupiter Deception". The main reason it was published was to dispell much nonsense written on the US/Canadian Force and to bring forward a complete story of British and Canadian involvement. Also, I noted in previous books that the chronological sequence of the battles was difficult to understand. It also corrects mistakes in Burhans/Supercommandos/We only move forward regarding the battle for Hill 720 etc. etc. Anyway Eric has the most complete library of titles available so check him out. It is now considered the official FSSF Association website.
