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).
Size of the Roman army By the size of the Roman army is meant the changes (increases and reductions) in the number of its contingents: legions, auxiliaries Praetorian cohorts, Urban cohorts, vigiles, and naval forces over the course of twelve centuries - from 753 BC to AD 476 (the Fall of the Western Roman Empire).
