I have updated the OP with the Ptolemaic, Baktrian, and Seleukid units. I'm sorry I didn't finish the Saka, but it's 2AM here in the USA and I want to get this thing out so that our European players can have a crack at it before I get home later today.

I didn't check it thoroughly because it's so late, and (as always) if you find problems, please inform me as soon as possible. Thanks!
