"Great engines of war, Citadel's Machineries of Destruction are superbly made, highly detailed multi-part boxed model kits, designed for use with the Warhammer Fantasy Battle rules but ideal for use with any fantasy wargame or for collectors. Each machine comes complete with a full crew, Warhammer Fantasy Battle statistics and special rules, and a specially written story fitting them into the Warhammer mythos." Which about sums the range up, except for MD9, the odd man out.
