Here is a quick link to a Civ4 forum about Srivijayan (Maritime Southeast Asian) armies would look like. I am from the region and have travelled within the region extensively too. National and tribal wear is legit. Expect i doubt any of the nations listed would probably not have employed chariots. lol as thalassocracy (sea power) the srivijayan empire would have employed many of the nations and tribes from the different islands within it sphere and probably beyond. Pls let me know if the link works and what you think.
