If anybody wants to get really geeky about tanks, a long time ago my kid brother had me paying for MAFVA membership as a birthday present. Lingerie for Vicky? And there I was all ready to mention long-rod penetrators. Or, as Doctor Who fans started saying after last Christmas, "Eat depleted uranium death, you repulsive alien weirdo!" So, if you model a Challenger tank, are you going to catalogue it as military or Doctor Who?
