Might have to stick around more than 25 years to see a carbine turn into a Roman officer.
A centurion (Latin: centurio; Greek: κεντυρίων, kentyríōn, or ἑκατόνταρχος, hekatóntarkhos) was a professional officer of the Roman army after the Marian reforms of 107 BC. Most centurions commanded groups of centuries of around 80 men but senior centurions commanded cohorts or took senior staff roles in their legion.
