I would like to think that Mr Gill would be able to answer that question, for I can only rely upon my limited knowledge on military science and of the French military system.
It is why I know of the Colonne Vuide, and why a commander of Troops can only form a great body of troops that is in their repertoire. I can even explain the theory behind having two lines of battalions deployed, or which battalion is the regulationing battalion within the Colonne Vuide.
Like yourself, I must also wait for Mr Gills response.
