The military chain of command was relatively uniform across the Empire. In each province, the deployed legions' "legati" (legion commanders, who also controlled the auxiliary regiments attached to their legion) reported to the "legatus Augusti pro praetore" (provincial governor), who also headed the civil administration. The governor in turn reported direct to the emperor in Rome. There was no army general staff in Rome, but the leading "praefectus praetorio" (commander of the Praetorian Guard) often acted as the emperor's "de facto" military chief-of-staff.
