What contain AI armies?

[Harovan]

In my current game I just destroyed a Zulu army, that contained

- 1 cavalry
- 1 infantry
- 1 swordsman,

which is a quite strange mixture. I'm curious, what contained AI armies you have seen in the game. Is there any logic, or does the AI stuff in it's armies all units that are handy at the moment?

I encountered a Russian army that contained two cossacks and a rifleman. Didn't seem that strange.

Most AI armies I've seen tend to contain either two fast units (knights, calvary, armor) and a slower one (spearman, rifleman, infantry), or, if its the ancient age, a set of three archers or three swordsmen.

The only time I've seen a really odd AI army was one time when I saw an army of one calvary and two warriors running around in the early modern age.
