Iv been trying to form all my divisions as such. I am actually the opponent of the guy who posted the question. Do the same rules apply when your on the defensive or is this formation best for an offensive only?
The short version is that that is a good setup if you do not have an arty division in the stack. The artillery division was discovered (by Gray Fox, IIRC) long after the game was published, and the setup you refer to was the old conventional wisdom. It still applies when, for whatever reason, you do not have an arty div to work with.
If you do have an arty division, and setting aside how you want to deploy your cavalry, a division with more line infantry can deal more damage and take more hits (hearts) than one that has artillery taking up combat slots. You will almost never be able to get a division with 17 line infantry in it (easier as the Union) due to all the mixed brigades, but a theoretically best stack will have an arty division, enough other arty to fill out the frontage mixed as evenly as possible into the other divisions (or even better left loose in the stack if you have CPs to spare), and as many combat units as you can cram into the non-arty divisions. Sharpshooters are a little weak but give other benefits to their division, so it is always nice to have one, (no more than one) but are not strictly necessary.
Cav have a bunch of weird properties in and out of combat and are worthy of a separate discussion, but are considered combat elements like infantry, rather than support elements like arty. In Corps scale battles they are safer mixed in with infantry than in an all-cav division, but are (mostly) not as good as infantry, element-for-element, so tend to water down a division's combat performance if there are too many in a single division.
I try to get at least 13 line infantry in each tip-of-the-spear division (assuming there is an arty div available) but "You go to war with the army you have, not the army you want" as the man once said.
