Roman legions, comprising 4,500 to 6,000 soldiers, were key military units in ancient Rome, renowned for their discipline, innovative tactics, and cultural impact.

These auxiliaries were recruited from diverse regions across the empire, bringing unique skills that complemented the traditional Roman military tactics.
