Allied Armies

In my current Roman campaign I use a mix of units for my Roman armies (2 of everything, hastati, principes, leves, triarii, hastati samniti, campanian cav. and pezzoi brutii) but I was wondering if it would be historically accurate to have armies composed entirely of allied units, commanded by a mercenary general recruited from their region? Cheers

P.S.-on the subject of mercenary generals some reason in Taras the description for my final Government Type 4 barracks doesn't say anything about recruiting a general! Is this a bug or is there some reason I can't recruit a general there? Cheers again

I've been using mercenary generals and regionally-recruited + mercenary armies to roleplay Pergamon in my campaign. It's had a client ruler there and my legions haven't set foot in Asia Minor since my war with the Seleukids.

I also used an "allied" army in one of my wars with KH/Makedonia, and indeed I had an Italian general marauding around Africa in my Third Punic War.

Should be able to recruit mercenary generals in Taras, I've been doing so for years.
