Chasing Emergence: Historical Development of Planning and Intelligence in Great Power Conflict [open pdf - 2MB]
From the Thesis Abstract: "Modern US Army doctrine requires collaborative planning by all War Fighting Functions. The years between WWI [World War I] and WWII [World War II] became the planning forge for the American military. Why did the United States develop integrated planning before WWII and how did it affect Army operations? The integration of intelligence, and other functional specialties, into interwar planning established a new planning paradigm in the US Army. Contributions from non-combat functional areas like intelligence, signals, and logistics became a central theme to interwar planning."
