The Roman Legion was one overwhelming mass, but not all people in the battle had the same job. Together, all the different types of people in the legion worked together to build a war machine that would take over all of the ancient known world.
The Roman Legion
This was the large unit of people that was able to take on very large groups of opposing forces. It was made up of many smaller groups, grouped into bigger and bigger ones. The lowest unit was the Pedites, the single armed soldier. Next would be the grouping called a Centuria, a pack of 100 men led by a Centurion. Two Centuria would team up to form a Manipulus. A Cohors would be made by binding 3 Manipuli together. A legion would be formed by getting together 10 Cohorts. The legion would be led by a general. When Caesar was commanding his legions, he made them smaller to make them easier to maneuver. His century unit only contained 60 men, instead of the standard 100. This changed the amount of men per legion drastically, from the standard 6,000 to a smaller 3,600.
The people were a lot like the mascots for the army. They would hold up a symbol to unite the soldiers, and lead them into battle. The Aquilifer was the man who held the Aquila (eagle), the symbol of Roman Army. This man would be carried by the Aquila into battle and lead the legion to victory. There were many things like the Aquila found in battle. The first of which was the Vexilla, this acted as a flag to rally small groups of soldiers. The Imaginifer would hold a statue-model with medallions hanging from it. Also found were the Signifers who were very educated men who stood in front of a Century, and the Draconius, a dragon-head with a fabric tail made to whistle in the wind.
