4. The Legionary Structure
The Roman army’s hierarchical organization, from small squads to vast legions, enabled flexible strategies and seamless operations. A legion typically comprised about 5,500 soldiers, divided into ten cohorts, each containing six centuries of 80 men. The first cohort was double-strength, consisting of 800 men. Each century was subdivided into ten contubernia, or tent groups, of eight men who shared a tent and equipment. This structure facilitated efficient command and control, allowing the Roman military to adapt swiftly to various combat scenarios (unrv.com).
