the.com/centurion

means A professional officer in the Roman army who commanded a century — originally about 100 soldiers, later closer to 80 — and formed the backbone of its discipline and command structure.

from From Latin 'centurio,' built on 'centum' meaning hundred, since each centurion led a 'century,' the basic tactical unit of the legion. The word reached English through Old French and Latin church usage, partly kept alive because the Gospels feature a centurion as a notable figure of faith, giving the word extra staying power beyond military history books.
