Warlord Games has new Aramean/Chaldean archers available over on their website.
From the announcement:
The Aramaeans and Chaldeans inhabited the marshlands of southern Babylonia and were formed into numerous tribes. The Chaldeans were said to be more organised than the Aramaeans. By the time of the Neo-Assyrian empire the two cultures would have influenced each other quite heavily, as well as being influenced by the Babylonians and probably the Assyrians that claimed ownership of the region.
