Play the Grand Campaign as the Italian Superga division. 

Proof of concept, not a finished product. None of the Briefings are done, only the first battle is fully customized etc. But these files, especially the Grand Campaign.txt, Tunisia.txt, and Longstop Hill.txt (Operation and Battle files) can be used as a template to create a German, Italiaan or US campaign based on the companiwes seen in the Main Force window of the Scenario Editor.
