Раньше было только в FAQ вроде что можно выставлять всю формацию целиком, сейчас точно в последних книгах сказано:
«When you are setting up, you can setup all of the units in a warscroll battalion instead of setting up a single unit. Alternatively, you can set up some of the units from a warscroll battalion, and set up any remaining units individually later on, or you can set up all of the units individually. For example, in a battle where each player takes it in turns to set up one unit, you could set up one, some or all of the units belonging to a warscroll battalion in your army.»
