This question was posted on AHF. It is an interesting one. I looked through my books, but I don't have anything that addresses this time period. Ceva's La condotta italiana della guerra gives several cites of books that might address this issue, but his study really begins right after Di Giorgio's tenure.

So I was reading an article on Commando Supremo and there was a part where they mentioned Mussolini's war minister proposing an interforce high command. The first one created was German in the 1930's so this would have been ahead of his time. Does anyone know anything about it?
