Many units can include a command group of some kind, dictated on the whole by the miniatures that are available, and detailed in the relevant Warhammer Armies book. Most units can take what we refer to as 'full command' – a champion, standard bearer and musician – whilst others will only be able to take perhaps one or two of these options. Light troops, for example, often do not have an option for a standard bearer, preferring not to draw the enemy's attention by waving a big gaudy flag. Command group models are always chosen as upgrades to normal rank-and-file models.
