How do you edit the veterancy for an unit? I noticed in modstudio every veterancy level references a file, but I couldnt find the file.
You can edit squad veterancy by navigating to
squad_veterancy_ext/veterancy_rank_info/veterancy_rank. This table only exists for squads, so you have to use the files under
sbps folder.
As seen in the screenshot below, veterancy rank 2 for pioneer squad takes 800xp.
By going down to squad_actions you will find a modifier which multiplies squad armor by 2.25.
