I owned this boxed set; Behind Enemy Lines, by FASA.  this was fun, more like the BATTLETROOPS set than the MECHWARRIOR wargame; anyway I used it exactly once to do a session based on a "Haunted Tank" comic book story...  the game got nowhere near a finish... the night ended before the session got far enough along to mean anything.  kinda like my Twilight 2000 session.  also, The game title is the same as my Initials...so there's that.
