Never mind the Lakota, check out the Americans. MS has recently updated the info.

[Americans] also have the additional power of receiving +3 Food, Timber, Metal, and Wealth for every non-Scout Barracks unit.

Holy Cow! That means every barracks unit brings in more resources than a normal villager! You can boom AND attack! That could be EVIL.

UPDATE: Nevermind. It ain't +3. We're not allowed to discuss detailed stats, so I shouldn't say what it really is (since it hasn't been released).

But while we're on the subject of Americans, I can safely say the Wonder the Americans will use their bonus on is NOT the Collossus. It's the Hanging Gardens. This wonder is the first (and only) thing you can build that actually increases knowledge gathered. With this bonus, plus the extra scholar per uni, Americans might even be faster boomers than the Greeks. But the Americans ALSO have the barracks troop bonus resource thingy going on.
