Non-fiction, video: Gwynne Dyer, "War," part 5: "Keeping the Old Game Alive."
This is part of an 8-part documentary series on the problem of large-scale war with modern weapons. This segment focuses on how NATO officers attempt to "keep the old game alive" by pretending they can fight a conventional war in Europe (setting aside Soviet doctrine, which didn't attempt to do so). It's a really good look IMO at how we prepared to fight a war in Europe in the mid-1980s when this game first came out.
