Not only does the Khanate start out with four towns, but they have the most mobile armies in all of Calradia. With just a little luck, you can easily kill, pillage, and burn the countryside of every nation in the game, as well as easily win field battles (even against Rhodoks, if you put a little planning into it). However, it is difficult to take and hold cities whilst fighting for the Khanate, as all Khergits are optimized for mounted combat. The best advice for the aspiring Khergit lord would be either to go and get troops from another faction to assist in sieges or completely overwhelm your opponents with your astounding numbers.
