Every experience star ads a level to either offense or defense. With defense being the first one raised. Eventually their strategic rating increases as well. Someone on the board once said every three stars, but it my experience it goes up faster than that (I once got Freemont to a 6, and there are not 12 stars available)
Experience makes a unit fight better. Experience can promote a militia to conscript, volunteer to line infantry, and conscript to regular. I think after two stars, and then they are reset to zero stars.
Units lose experience points when promoted. Based on my play (and getting units down to zero effectiveness multiple times), I do not thing they lose experience points when they get replacements.
Generals lose some experience when promoted. They also can lose their ratings, if they were historically worse as Army commanders than Division commanders, like Hood.
