罗马共和末期到帝国初期这段时间,它的军队由罗马公民的军事组织逐渐演变为职业化的常备军,每个军团都拥有自己的番号、名称、军旗、团徽、服役期限、军饷及退役津贴标准、还设立了军事国库并建立了军事殖民地以安置精简下来的士兵和退伍老兵。这些举措使得罗马军团成为维护帝国统治的强有力的工具,为罗马帝国的繁荣和强盛奠定了基础。 During the period from the end of the Roman Republic to the beginning of the Empire, its army gradually evolved from a military organization of Roman citizens into a professional standing army. Each army regiment has its own name, flag, emblem, length of service, salary and retirement benefits Standard, a military treasury was also established and a military colony was established to house streamlined soldiers and veterans. These moves made the Roman legionaries a powerful tool for maintaining imperial rule and laid the foundation for the prosperity and fortitude of the Roman Empire.
