In the Aztec list there are arrow knights listed, yet as far as I know they didn't exist as an order.
There are some (possible "arrow knights") shown in older pictures but nothing to say that the order existed.
Anton Hoffman being the prime candidate for this and his only have arrow shaped javelins not bow.
Could be wrong though

thank you for info. They are not knight, but foot warriors.
I will make some research and foward your imput to the person that made the list for a further check on this.

we are considering to change them in simple FL troops. They used this big javelin to fight in melee so they could be best classed FL than S.
