OK, so it's only my second game (first as the CSA) and I effed up by trying to march Jackson to Baltimore as winter hit, but otherwise I'm doing pretty well I think.
Anyway, Bragg and Hardee (I think) have the training master special ability which gives 1 pt of experience to each unit in the stack.
Maybe I'm gaming this ability, but so far, I have bought maybe two brigades of infantry. Instead, I buy as much militia as I can, put them in uber stacks in "training camps" and wait. I use New Orleans and Charleston (also means I have good entrenchments for if the Union try to land) and feed the units to the front as much improved infantry. Sure, they don't have the support elements a real brigade would have, but that's what divisioning is for, right?
Is there a cap on the level a unit can attain under a training master? I don't mind spending time to get militia to infantry, but at some point you need to see the elephant for a unit to become more experienced.
I mean a * with nice stats like Sherman is OK, if he does well with an independent command you can get a good corps commander out of it, but otherwise so what? As a * they'll always be in trouble vs even an average full-sized corps just because of size.
The entrentchers etc that don't need to be in command to benefit are handy, but right now I am a CSA with enough money to embargo cotton whenever it becomes available and not worry about it (well except when it backfires).
Sorry for the rant, I would like to hear who other people think are important *s, just got carried away with my little trick.
