Some of the formations look good just as they are. But I want to see the special rules for fielding them. Surely that Infinite Phalanx has some additional rules, such as better reanimation or the units going back into Reserve when destroyed to come on again. Maybe the formations have no extra rules but then what is the advantage of fielding an Assault Company over a Battle Company?
