The skeptics can't deny the skills bowmen had to master in the days before gunfire, especially mounted or chariot-borne archers. The Parthians had no stirrups. The Mongols, as x SF med points out, were superb mounted archers. Pardus is right that we don't give enough credit to the skills ancient warriors had to master to survive the brutal close combat of their day. These guys had to be part acrobats.
