removing completely a unit means removing each line where the unit is, need to analysis each table/file in the pack file

if you just want to just remove the unit from teh faction without deleting from the entire mod:

=> in "units_custom_battle_permissions_tables" remove the lines where there are the units you want to remove

=> in "units_to_groupings_military_permissions_tables" remove same type of lines

you seems just wanting to delete all roman one, so try to look for the faction "rom_roman" and "roman"


the otehr tables just say the unit stats/building/training/skin and other details, the tables i show you are the one which "choose" to give the unit to the faction in custom battle/campaign
