Besides the legions, there were also specialized military units, such as cavalry units and naval forces, which added to the total number of men in the Roman military.
Total Size of the Roman Military
The total size of the Roman army at its peak is estimated to have been between 300,000 and 500,000 men, though the numbers fluctuated depending on the time period and military campaigns. The Roman Empire was vast, and the army had to be large enough to defend its borders and maintain control over its territories.
Conclusion
In summary, the Roman army was composed of a significant number of men, with the average Roman legion consisting of about 4,800 to 5,200 soldiers. In addition to the legions, the Roman military also included a large number of auxiliary troops, which could bring the total number of soldiers to several hundred thousand at any given time. This vast and organized force was one of the key factors that allowed Rome to dominate much of the known world for centuries. shutdown123
