Can I customize the AI of units?

I'd like to know if it is possible to program the AI of units. Most of the mod tutorials I've found are just about tweaking the XML files which can affect a few hyper parameters such as how aggressive they are, but nothing where you can just rewrite their decision code. I've also looked through the lua scripts in Civ 5's Assets directory but can't find anything relevant.

I've seen some posts that have hinted that some of the bigger mod overhaul packages can create custom AI, but I don't know how I might get started on this or if maybe I'm misunderstanding things. Is there a way to customize the AI?

Absolutely, but you'd need a decent grasp of lua to do so.
