Not a bad idea. I have destroyed quite a few armies with 7-10 warbands a piece in them when the Gauls sent them to attack my territory; every Gaulish army I have encountered has been a mass of warbands and the AI has been admirably agressive in attacking my borders and raiding my farmlands. As far as I can tell each of those warband armies was replaced by another warband army, and certainly the Gaulish lands are packed with more warbands. It is hard to tell exactly what the AI does with its build orders though ...

I shall go on the offensive to kill several thousand hairy barbarians and see what crops up to replace them
