Centurion

A centurion (Latin: centurio; Ancient Greek: κεντυρίων), also hekatontarch (ἑκατόνταρχος, hekatontarchos) in Greek sources, or, in middle Byzantine times, kentarch (κένταρχος, kentarchos), was a professional officer of the Roman army after the Marian reforms of 107 BC. Most centurions commanded 60 to 80 men despite the commonly assumed 100, but senior centurions commanded cohorts, or took senior staff roles in their legion. Centurions were also found in the Roman navy.
