Quote:Luttwak, E.N., The grand strategy of the Roman Empire (Baltimore 1976) 255p.
I have it too And the book I mention is basically a rebuttal to "The grand strategy..." written a few years after during the 80s.
Quote:Therefore you get the 'defense in depth' and the development of the Mobile reserve (already under Gallienus, probably, not Constantine)
From my understanding ; yes and no. Gallienius didn't implement any permanent changes. Gallienius assembled his mobile forces in an ad hoc manner and during a civil war on two fronts to boot. Whereas Constantine implemented reforms during his decade-long reign as sole Emperor.
You could also say that Severus had a strategic reserve which comprised of the II Parthica legion plus the Praetorians making a combined force of some 40,000 men based in Italy. Yes,he could have used them as such but didn't. Nonetheless, it foreshadows what was to occur in the later empire. I think, from what I've read, that goes for Gallienius as well.
