A lot of the group classnames can be found here: https://3cbmod.wordpress.com/released-mods/3cb-factions/class-names/ . I still need to create the individual unit classname list. As for Faction classnames, if you look in that link, you'll see it is usually the faction (lets use the AAF) and then an _ and the side (so B for Blufor, I for Indfor etc...). For example, Blufor AAF would be Faction = AAF_B; You can get most of the faction names from the middle part of the group classnames for now. I will be making a master list for the next release though.

cheers

or just look in the config viewer in-game ;-P
