The picklist for the AI also takes into account the actual availability of certain types of units for that nation at that time. So if certain types of armor are included int he OB but were 'experimental' or only available in very small numbers the computer is unlikely to get them, or if it does only a few.

Set the points yourself manually or better yet, buy a force which is barely large enough to cover all sectors of the map. Battles are a lot more fun if they're not slugfests with large forces moving at each other over the whole length of the battlefield. That's my opinion at least...
And oh yeah, japanese infantry is especially tough to deal with. So it's not really a good measuring stick as far as dealing with infantry goes.
