Faction unit selection priority?

[Burns]

I've been trying to figure something out. In a custom battle, how can I change a faction's unit priorities? The Saxons for example love to use lots of infantry, but how could I get the AI to select more cavalry? How can I have a faction (the Alemanni) select more ranged units instead of melee units? Is that related in any way to their descr_strat AI parameters (or does that only have an effect on the campaign?

hmm, i think it only effects the campaign, but as a general rule, i find that when i let the computer make a random army, it usually has lots of general units and quite a few seige units.
