If you want to distinguish and have Libyans of the Carthagenian Empire and Native Libyans, yes they would probably be different. I would say, not as heavy armor. No hoplite like units. Heavy spearmen is a maybe yes or maybe no thing. I would say probably at least light or medium cavalry or both, spearmen, skirmishers, maybe even heavy spearmen but probably not as good armor or weapons as that of carthage libyans. And I would probably say, chariots too. Maybe archers, but maybe not slingers.
