First up some Arab tribesmen from the dusty interior (of my miniatures drawer), followed by exotic Maotians from the Black sea. I don't know why I bought these from Vendel many years ago, perhaps to mix in with a Celtic warband or to use as vassal infantry for Scythians. Whatever the reason they have a character all of their own and have served in many a previous skirmish line. Note, usefully they carry both javelins & bows.
Next up a couple of small units of Persian archers, from Persia.
