Hi,
Looking at the Carolingian armies in the Frankia list, I found a spelling mistake.
There is talk of 'Heerbaan' instead of 'Heerbann'. Although the 'Heer' bit is identical in meaning, i.e. 'army', the second bit is like calling the system of military organisation a motor way/main road.
Granted, 'Heerbaan' got its name from the reason it was there, to allow the army to travel on it (basically still the Roman Road), but the organisational system of the armies was the 'Heerbann'.
