T01 will be used as the default if one unit is in the scene.
If More then one unit is in the scene the following TGA's will be used
in sequence.
T01 through T0x
I believe I heard that no more then 6 or 9 ever appear before the
count returns to T01.
The only way to make them Theater specific would be to do a new unit
using the example from SH4 (Use 3D Model........)
then in the Roster file (Use image file or however stated)
I know useing the 1st part works.
Never tried the second.
But then you need to edit all Campaign files to use the new units.
A PITA all the way around.
