The AUS has been moved to the center, and thus apart from the evangelical radicals, the other groups (I am looking at you George Moseley and Lindberg) are under a faction called "Constitutional American Republic", as such the AUS can now make a detente with the Internationale
The AUS army doctrines are under different officers, however I don't know any one of them
Assuming you go for the christian radicals, however, you can adopt Gerald K Smith who has no military insight whatsoever to make your army, and it is like what you would expect from a 2000s game showing the soviet army
Here the map
The black revolt only spawn if you go too harsh with the Constitutional american republic
Some leaders of the constitutional american republic, William "Alfalfa Bill" Murray, Charles Lindbergh, General George Patton and William Bell Riley
from what I can understand, the CAR is the new AUS, as the AUS is the "evil" faction on normal kaiserreich but got one less evil path being Huey, now the AUS is a "good" path with the CAR being the "evil" faction with one less cursed path, that path would be Lindberg
Now, you might be wondering "If this is the less cursed path, what is the most cursed one?"
Alfafa Murray is basically a integralist on the sense that he believes that "until point x of history everything was going all right, then from this point on everything collapsed", he wants to turn the entire USA into the pre civil war south with added antisemitism, the only thing he lacks is the slavery, but he probably comes close to that
The second most cursed path is the christian fundamentalist one, under someone called Armstrong , I really would like to paste his wikipedia here but I have no idea who he is
The third is the new KKK, you have a path with the old KKK also. The New KKK path is the closest you have to Pelley in normal Kaiserreich.
Different from the AUS, the CAR is way more belligerant and can take more foreign policy paths, from going full "AMERICA FREEDUM!" to a pro british policy, or a pro german, or just close like the AUS usually do
