Various Scythian tribes served in Persian armies at different times - Dahae, Sakae, Massa-wotsis - but I just lump them together as Scythians. This lot are the ones allocated to the 'main' (ie mostly Garrison) Persian army. At the moment, one unit based as Sparabara plus a unit of light cavalry. In the invasion of Greece the Sakae were brigaded with the Bactrians as part of Corps VII.I can't remember whether it was Head or Sekunda who suggested that the infantry would have been Sparabara rather than open order lights, but I've followed that view with these.
This component was scheduled to be much bigger than this but has been overtaken by events and will have to wait for reinforcements - though 2 units of 'S' Range cavalry were acquired they have been allocated to Athens and Assyria!
Should be 12 cavalry, other base must be foraging or something.
