Yes, that is true.
I like many things about the USSME official histories. The glaring gap in the histories are an overarching account on the army throughout the war. Volumes similar to the UK's
Grand Strategy and
Central Organisation and Planning or the American
Army Ground Forces and The War Department series. The
Verbali delle riunioni tenute dal Capo di SM Generale and the
Diario storico del Comando Supremo, while useful, are poor substitutes for a comprehensive account of the Italian military during the war.
The USSME books are organized by campaign. There isn't an account of Italy itself until the
Le operazione delle unità italiane nel settembre-ottobre 1943 volume. What was happening in Italy between June 1940 and September 1943? There aren't any book that connect the various theaters/campaigns in terms of resourcing, production, recruitment, etc. While
L'esercito italiano all vigilia della 2ª guerra mondiale provides a good overview of the military at the start of war, it is merely that: an overview. Few details such as which divisions were considered 100%, which were incomplete, etc. Which units had their 47/32 c.c guns and which didn't. Production, shipping data, etc. remains to be ferreted out using multiples sources, yet remains incomplete.
L'esercito italiano tra la 1a e la 2a guerra mondiale is good for the desired army, but what was the actual army with which Italy entered the war?
A series that might have helped is
L'esercito e i suoi corpi. Published by the USSME, only four books were printed before the series was stopped incomplete. A loss for researchers.
Ah well, an opportunity for some aggressive researchers.
