Basics
In most cases it'll be fairly obvious which troop type category a model falls into, but as troop type is essentially an extension of the characteristic profile, you'll find that information in the relevant Warhammer Armies book. Most units in Warhammer conform to one of the following types. Some particularly unusual units are literally in a class of their own – we call these "unique" units. Such troop types have special rules that govern them and only them, clearly stated in their entry.
