In each commanders JSON file, which are located in: Code: pa_media_directory/pa/units/commanders/particular_commander/particular_commander.json
They appear to be here: Code: ./ui/main/shared/js/catalog.js However shadowing the file in a client mod and renaming things doesn't work. Probably because the catalogue is always updated whenever something tries to load it. What are you trying to do? BTW grep or similar is a good tool to find out things like this. I searched for "Rallus" in the game files to find the catalogue. "Rallus" is not present anywhere except the unit JSON, the catalogue, and the galactic war faction files.
