The Iron Cap Prince's Army is a Home City Card in Age of Empires III, that sends Flamethrowers and Changdao Swordsmen. The Flamethrowers are Infantry units that are effective against all melee Infantry Units, but lose to Cavalry, and ranged infantry that can stay out of its range. Changdaos are effective against Cavalry making the shipment well balanced and effective, and lose badly to skirmisher and archers lineups as well as culverin and falconet combo.
