This is a late Roman cavalry unit made for Primordial Stews Rise and Fall of the Roman Empire mod. Late Roman cavalry were much better than the cavalry during the Republic and Early Imperial Period. The unit is based off of the Roman cavalry on the cover of the Warhammer Supplement book, Fall of the West. PLease offer comments here:
