What unit from the Roman Army consisting of centuries enjoyed more prestige than the Roman navy?
Roman legion A Roman legion (from Latin "legio" "military levy, conscription", from "legere" "to choose") was the largest unit of the Roman army, evolving from 3000 men in early times to over 5200 men in imperial times, consisting of "centuries" as the basic units. Until the middle of the first century, 10 cohorts (about 5,000 men) made up a Roman Legion. This was later changed to nine cohorts of standard size (with 6 centuries at 80 men each) and one cohort, the first cohort, of double strength (5 double-strength centuries with 160 men each).
Legio VI Ferrata Legio sexta ferrata ("Sixth Ironclad Legion") was a legion of the Imperial Roman army. It probably originated from the Republican general Pompey's 6th legion in Spain. In 30 BC it became part of the emperor Augustus's standing army. It continued in existence into the 4th century. A "Legio VI" fought in the Roman Republican civil wars of the 40s and 30s BC. Sent to garrison the province of Judaea, it remained there for the next two centuries.
