Basically what Monkwarrior said. The unit cards must be correspond to whatever the unit's dictionary name is. If for example you were to add Seleucids to the ownership for the Greek ballista, then the new unit card would still have the same name as the Greek one, and you just stick it in the Seleucid directory. Remember to create a UI\units\factiontitle and a UI\unit_info\factionatitle directory as I don't think the game has one as standard, as the unpack tool merely makes a \pack directory which the game otherwise ignores.
Btw, I thought you used my Carthy archer mod? If the files were unzipped into the right directories, that unit should work anyway.
