I'm busy prepping some new additional units for my DZC armies
First off, a pair of Tormentor Heavy tanks for the Scourge
The Tormentor is a bit of a specialist unit dedicated to burning infantry out of buildings. Although technically a heavy tank it is useless against other tanks, and its armour is not really any better than the standard MBT, but it is a bit more durable, and in addition it can carry a trio of Razorworms - basically giant intelligent centipedes with teeth & claws used to clear buildings of infantry.
Sorry for the blurry shot - will try and get a better one . I suppose the nearest real world counterpart would be a Churchill Crocodile
