Имперская армия
Circle troops () were the contingents of soldiers that the Imperial Circles ("Reichskreise") actually placed at the disposal of the Army of the Holy Roman Empire or "Reichsarmee". Following the Imperial Defence Order ("Reichsdefensionalordnung") all imperial circles in the empire were obliged to provide contingents of troops, although not all did so in the event. The Imperial Register ("Reichsmatrikel") laid down how many troops the individual Imperial States had to make available to the "Reichsarmee".
