Nowhere near 1:1, although their elite infantry are called stormvermin. Probably more a take on industrialised society in general

They're a survival-of-the-fittest society of ratmen with no redeeming features. Hierarchical and authoritarian, they've got enough numbers to easily conquer the world and they have all sorts of hacked together high-tech stuff like nukes and gatling guns and sewn-together monstrosities etc, except they're all so busy constantly trying to stab each other in the back that they can never get anything done. And they're all so completely cowardly that no chud is going to unironically stan them for "martial honour" or anything like that
