Basic Structure of a Legion
Most legions are made up as follows. Some however have more or less cavalry, especially more recent legions, adding more heavy cavalry and decreasing the number of light cavalry.
- The Legate will be the commanding officer.
- The Camp Prefect will take charge in his absence.
- Six staff officers which can be a mixture of Tribunes and Adiuvators.
- Other headquarters staff including a Chief Surgeon, Chief Centurion, Quartermaster and Armorer.
The Legionnaires and Cavalry:
- 10 Cohorts each commanded by a senior centurion.
- The 1st Cohort is double strength, with twelve centuries, commanded by the chief centurion. The elite unit which will often be the legions first unit into any battle. Should the chief centurion be absent or killed in action the senior centurion from 2nd Cohort will take his place. The most experienced centurions are in the first cohort. A replacement senior centurion would be promoted from 1st Century 1st cohort, his replacement would be 2nd Century 1st Cohort centurion and so on.
- The other nine cohorts have six centuries each.
- A century is made up of 80 men commanded by a centurion with an optio serving as second in command. Each century is split into ten eight man sections which share a room or tent, depending on whether they are in the field or in barracks. In addition each century has a clerk and standard bearer.
- When at full strength the legion will have 5400 legionnaires, plus cavalry support.
