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).
Droungarios of the Fleet The "droungarios" of the Fleet (Greek: δρουγγάριος τοῦ πλοΐμου/τῶν πλοΐμων , "droungarios tou ploïmou/tōn ploïmōn"; after the 11th century δρουγγάριος τοῦ στόλου, "droungarios tou stolou"), sometimes anglicized as Drungary of the Fleet, was the commander of the Imperial Fleet (βασιλικὸς στόλος, "basilikos stolos", or βασιλικὸν πλόϊμον, "basilikon ploïmon"), the central division of the Byzantine navy stationed at the capital of Constantinople, as opposed to the provincial (thematic) fleets. From the late 11th century, when the Byzantine fleets were amalgamated into a single force under the "megas doux", the post, now known as the Grand "droungarios" of the Fleet (μέγας δρουγγάριος τοῦ στόλου, "megas droungarios tou stolou"), became the second-in-command of the "megas doux" and continued in this role until the end of the Byzantine Empire.
