LegIIAvg represents the Roman army
from 43AD, the time of the
Roman invasion of Britain
, until the end of the 2nd century AD.
During that period there were circa 28
in the order of battle. Each
was structured as follows.
The smallest administrative unit was the
conturnium of 8 legionaires
century of 80 legionaires
centurion, 1 Optio and 1 standard bearer.
6 centurys formed a cohort of 480 legionaires, 6 centurions, 6 Optios and 6 standard bearers and 10
formed a legion. Cohorts 2 through to 10 inclusive had the structure described above however cohort 1, which was the senior
lead by the senior centurion known as the
, had a different structure.
The 1st cohort had only 5 centurys but each century was a double strength century of 160 legionaries. This gave the 1st cohort a strength of 800 legionaries and 15 officers. Thus if we include the command element of a legion its strength is in excess of 5300 men.
In time of war a Roman army would have its
legions who would be supported by auxiliary units, artillery, medical staff and cavalry
to make a formidable field force.
