Persian Sparabarai
The front rank of a unit of archers were equipped with a large shield made from cane pushed through leather. When the leather cured it bound the cane together forming an incredibly resilient construction.
From behind this shield they could protect the rear ranks using a spear, they were usually equipped with a Kopis, Akinakes or Sagris sidearm.
Persian infantry are depicted in Greek art as wearing a cuirass until about 450 when it is thought that Persian tactics changes, as did the role of the infantry.
These figures are based on Persians depicted on the Oxford Brygos cup, painted around the time of the battle of Marathon.
