LP is right. Cavalry tend to be much less skittish to command. I have had several massed Cavalry charge - counter-charge fights where the fighting continues more than the old version. They tend to break/fall back less.

Also, I've noticed some superb, (and probably accidental), combined arms work by the AI. Cavalry comes forward, I form square, theres ALWAYS a battery somewhere close-up firing into the squares, and then up hustle the Infantry columns. Hard to beat.
