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".
Battalia (formation) From the late 16th century into the 18th century battalia, was a description used both for the positioning of units in an army (or navy) on a battle field and the formation in which individual units deployed for battle (battle array or battle order). Sometimes it was used to describe the main body of an army deploy for battle but excluding the wings and other units such as those deployed in front of the main line in skirmishing formation etc. Battalia differs from battalion which is generally the smallest military unit capable of independent operations and would have formed up in its battalia when going into battle.
