The stats are quite broken in many cases and thus not indicative of actual performance in combat, which makes this all the more valuable IMHO. What you see if not what you get from the unit stat tab.

I have to say, however, the fact that peasants able to rout Italian Spear Militia (equal valor captain stacks in both campaign and custom battle) etc. is fairly ridiculous.

At any rate, I'd be happy to share my experiences with my Turks. (This does happen to coincide with finals perod though). They were my favorite faction in original MTW partly due to a crazy ransoming rush I came up with but also their amazing unit roster.
