more questions,
Qiout: from TW.com, how to add units to a faction:
After constant fiddling with this, I found a way of adding actual new units (although I don't think I'm the first one to do so).

First, the export_descr_units.txt file. The easiest thing to do is figure out which kind of unit you want it to be, and copy the data for a similar existing unit. Rename it to what you like, and change the dictionary name (let's call this one Bob).

Next, go into the export_descr_unit_enums.txt and add the three bits on the end for bob:
Bob
Bob_descr
Bob_descr_short

Third, go into the text folder, and open export_units.txt. At the bottom, put the description for each of the three items above:
{Bob} Bob
{Bob_descr}
This is the long description of the unit in-game
{Bob_descr_short}
This is the short description... duh.

You probably want to be able to actually use them in the game, so the next part is to add a unit card and an info picture. Create (or go to) the folder data\UI\UNIT INFO\Faction Name, and add a tga image (dim: 160 x 210), with the name of your unit tag followed by _INFO:
Bob_INFO.tga
Go to data\UI\UNITS\Faction Name, and add a card image (dim: 44 X 64) with a # sign and then your unit name:
#Bob.tga

This should allow you to use the unit in custom battles with the faction you specified in the descr_unit file.

To add them to the campaign:
Go to export_descr_buildings.txt. Under the building type of your choice, enter something like:
recruit "Bob" 0 requires factions { roman, }

Create (or go to) the folder data\UI\units\construction, and add an image (dim: 42 X 56) with a # sign and then your unit name:
#Bob.tga

now, where can I find those supplied/ existing tga files for the unit cards?

thanks again
