All armies had a chain of command from bottom to top. The Romans were indeed formidable and the foremost military of their time but the concept of the army corps was not developed and perfected until the Napoleonic era and the concept of a professional general staff responsible for the development of strategy and guiding the war fighting efforts of a nation to achieve its national objectives was not created until just after the Napoleonic era. As great as the Roman military achievements were they had nothing like that that we know of.
