When you think of roman military structure, you think Contubernium, Century, Cohort, and Legion. A legion consisting of a few thousand men, and led by a Legate. But I can’t seem to find any unit size above a legion, although it seems like they would have higher organizational levels seeing that there were quite a few legions. If no organizational structures, were there any formal positions above Legate? Or was that level of command reserved for the emperor/consul?
