What unit from the Roman Army consisting of centuries enjoyed more prestige than the Roman navy?
Roman navy The Roman navy (Latin: "Classis" , lit. "fleet") comprised the naval forces of the Ancient Roman state. The navy was instrumental in the Roman conquest of the Mediterranean basin, but it never enjoyed the prestige of the Roman legions. Throughout their history, the Romans remained a primarily land-based people and relied partially on their more nautically inclined subjects, such as the Greeks and the Egyptians, to build their ships. Because of that, the navy was never completely embraced by the Roman state, and deemed somewhat "un-Roman".
Sacred Band of Carthage The Sacred Band of Carthage is the name used by Greek historians to refer to an infantry unit of Carthaginian citizens that served in Carthaginian armies during the fourth century BC. The presence of Carthaginian citizens fighting as infantry in these armies is unusual as Carthaginian citizens usually only served as officers or cavalry in the Carthaginian armed forces; the bulk of Carthaginian armies were usually made up of mercenaries, infantry from allied communities (who might be Punic colonists), and subject levies.
