So far, the rules we've discussed cover the most important and most prevalent of troop types - infantry. We've started there because infantry are the 'standard' troop type in Warhammer. Of course, a Warhammer battlefield is home to all manner of weird and wonderful creatures, from charging knights to towering Giants, mighty cannons to multitudinous swarms. These more unusual troop types have particular rules attached to them, or use elements of the main rules in a different way to infantry, so let's take a moment to look at them now.
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.
In addition to their troop type, some models might also be noted as being characters. We're not going to worry about characters here, however – characters are such a powerful and important part of Warhammer that they have a chapter all to themselves later in the book.
Models and Base Sizes
Each model should be mounted on a base to determine the width and depth of the unit. Each Troop Type has different approved base sizes, which are listed below.
In some cases, you might be using a model that requires a larger base than described for its Troop Type. This is completely fine, as long as you try to keep it as close as possible to the normal approved base sizes. However, you may never have a base size that is smaller than the approved base sizes listed here.
