Battle difficulty

[Byte]

Hello, does the computer have different AI routines in easy/medium/hard or is the difficulty change only the morale bonuses?
So basically is the computer smarter in higher difficulties or does it just get numerical bonuses?

I've found the AI to get more battle bonuses than getting smarter. I've played custom games to try and figure it out and I've noticed they won't make so many dumb mistakes, but you can usually get away with flanking them pretty easily on both easy and very hard. The biggest thing i've noticed is moral boosts and attack ability. Recently, I've been playing with civs that use spearmen and on very hard light and heavy cavalry can defeat nubian spearmen and militia hoplites even when attacking the front.

The AI gets a bit smarter on harder battle difficulties, but not much. You can still use the same strategy to beat them all the time if everything is right. Really the only bonuses that they get are morale boosts and ridiculously stupid fighting bonuses in battle. On easy difficulty, put 1 Hastati against 1 Gallic Warband, Hastati win with not so many casuaties (this is just a melee fight, nothing sprecial). Put the same units up against each other on Very Hard and the Gauls have a good chance of winning, or at least inflicting more casualties, even if the same exact strategy was used before.
