Against Roman and Greek heavy infantry, these horsemen have little trouble in staying out of range while wearing down the enemy.

These are tough Saka from the north-eastern frontiers of the Parthian Empire and the lands beyond. Living a tough life, they learn to ride as soon as they can walk, and they are masterful horsemen. The Saka nomad's primary weapon is the composite bow, the new asymmetrical so called 'Hunnish' bow rather than the Scythian composite bow. The steppe pony they ride is a hardy beast, though small and shaggy. Considered unattractive by more settled folk, it is well able to survive in the harsh steppe climate and can thrive on grass alone, not requiring the daily grain feed of more finely bred mounts. This allows their nomadic riders to range far and wide, not hampered as more traditional cavalry would be.

Historically, Saka cavalry fought both within and against Parthian armies. Shooting accurately with a bow while on horse-back took long training and, thus, many “Parthian” mounted bowmen were levied from the vassal tribes on the Empire’s border marches, who were renowned for their horsemanship and fighting skill. Most Saka horsemen in Parthian service were part of contingents supplied by tribal allies/subjects, but some might have been mercenaries. Occasionally, they appear to have formed their own units and fought under their own chieftains. In any case, they have their own sense of loyalty and cannot be relied on to fill important roles. They could be used, though, to bulk up the line of horse archers in a Parthian, providing the Parthian Kings with another vital source of light cavalry. When fighting for themselves, the Saka proved a force to be reckoned with. Hostile Saka managed to slay two Parthian kings in battle and when the Parthians finally drove them out, they coalesced with related groups of nomads from further east to overran Northern India, forming the Indo-Saka kingdoms there.
