What are you talking about!The Carthaginians only have 3 or 4 units that are native to Afriqya(not Africa im talking about Punic citizens).I can only think of the Sacred Band(cavalry and phalanx)and the really bad Punic citizen militia.
The elephants,though native to North africa,were not Carthaginians but North africans,or Indians,in the employ of Carthage.
The Liby-Phoenician spearmen were half breeds,not of pure Punic descent,and so could not attain the priveleges of Citizenship.
Im sure if you actually the look at majority of recruitable units are foreigners(cant really remember as RTR and EB have merged in my memory)
Thats the Benefits of doing a massive Carthaginian thesis,based on Hannibal's War

and they did have massive armies,the first punic war was said to have caused more deaths than any other war in Antiquity(even Alexanders campaign to destroy the Archamedian empire)with over 50,000 roman citizens dead,not including the 100sof thousands Levies,allies,sailors and actual Carthaginian forces lost through out.
