Dragon ogres

Dragon Ogres are a Warriors of Chaos melee monstrous infantry unit introduced in Total War: Warhammer. In battle is the only time a Dragon Ogre can die, so they fight with a powerful fury.

Description
Dragon Ogres are amongst the most ancient of the world's living creatures. Their incredible longevity, as with almost all things supernatural, is the work of the Chaos Gods. Aeons ago, the elders of their race made a pact with the Ruinous Powers, embracing damnation in order to save themselves from a slow decline into extinction. They were given eternal life, and in return, the entire Dragon Ogre race put themselves at the command of the Dark Gods. Since that day, the Dragon Ogres have carved their names across the ages as immortals who can only die in battle, monstrous beings that rouse themselves only in the name of destruction.

Strategy
The Dragon Ogres are the anti-large mobile unit for Chaos. They lose speed compared to legit cavalry but gain improved melee stats. Notably, they also have Scaly Skin for improved missile resistance. They are good for hunting down large units and can also devastate infantry if necessary.
