藩镇对唐五代时期的各个方面都产生了重要影响。就军事制度方面而言，藩镇军制推动了唐五代时期的中央禁军统兵体系和武官制度的变革，重塑了唐五代军制。唐后期中央禁军主动引入藩镇使府体制，全面改造了旧有的武职事官统兵体系。德宗贞元十二年设置统领神威军的中护军、神策军的护军中尉，标志着两支最有实力的北衙禁军“使府化”完成。宪宗元和十三年，六军辟仗使置印，可以直接统领六军。至此，北衙禁军全部实现“使府化”改造。唐后期北衙诸军中，神策军使府体系最具代表性，该军也是唐五代第一支采用使府体系的禁军。唐末藩镇内部对牙兵与亲军进行了整顿，成为五代侍卫亲军的源头。后梁时期的“侍卫亲军都指挥使”仍较强地继承了藩镇时代“中军指挥使”的特征，只能临时调度出征期间的侍卫诸军，而驻京期间则改称“在京马步军都指挥使”。侍卫诸军直属于皇帝本人。后唐庄宗时期侍卫亲军结构仍然松散，但参考“帐前军”系统的发展程度，侍卫亲军很可能已经分马步军统辖。后唐明宗彻底整顿了侍卫亲军，使之真正成为了一支结构完整的军队。侍卫亲军在随后的发展过程中出现了跋扈现象，与此同时殿前诸军被整顿成一个完整的系统。侍卫亲军与六军、侍卫亲军与殿前军先后构成了制衡关系，五代朝廷防范军队作乱的策略几乎就是藩镇时期牙兵、亲军关系的翻版。唐后期藩镇内部发生了幕府武职阶官化，其高峰是形成了“节度使府阶衔体系”，这一体系促使节度使府系统下的武职发生分化，一部分脱离军事差遣，成为带武职衔的非统兵军将；另一部分以“指挥使”名衔为标志，成为固定的统兵军职；还有一批带武将衔的非军职也参与到军事行动中。五代时期，这三个群体分别与内职和禁军军职发生联系。这对唐宋时期的武官制度变化产生了直接影响。唐初的武职事官体系完全空名化，宋初则形成了以武阶官为主体的武官体系；联系这两个变化的中间环节就是幕府武职阶官化。唐宋武官制度的变化过程可以高度概括为武职事官阶官化、幕职阶官化和内职阶官化三个连续的过程。

Fanzhen（藩镇） had an important influence on all aspects of Tang and Five Dynasties. In terms of military system, the Fanzhen military system promoted the reform of the central military structure and military officer system in the Tang Dynasty and the Five Dynasties, and reshaped the military system in this period.In the late Tang Dynasty, the imperial army of the central government took the initiative to introduce the system of office of the military governor（节度使府体系）, which completely reformed the original military system. In the twelfth year of Zhenyuan（贞元）, Emperor Dezong（德宗） of the Tang Dynasty set up an official named Zhonghujun（中护军） to lead the Shenwei（神威） army and an official named Shencezhongwei（神策中尉） to manage the Shence（神策） army, which marked the completion of the reform of the two most powerful imperial armies. In the 13th year of the reign of Emperor Xianzong（宪宗） of the Tang Dynasty, the Liujunpizhangshi（六军辟仗使） had the seal and could directly command Six armies. By this time, the reform of the imperial army of the central government had been completed. Among all the armies in the late Tang Dynasty, the system of office of the military governor of the Shence army is the most representative. It was also the first imperial army to adopt such a system of administration during the Tang and Five Dynasties.At the end of the Tang Dynasty, the Fanzhen carried out a rectification of the governor's private army（牙兵） and trusted troops（亲军）, which became the source of Emperor's Personal Army（侍卫亲军） of the Five Dynasties. The commander of this army in the Later Liang Dynasty still inherited the characteristics of the old times. It can only administer the army temporarily for the duration of the war. The Emperor's Personal Army remained directly under the authority of the emperor. During the reign of Emperor Zhuangzong（庄宗） of the Later Tang Dynasty, the structure of this army was still loose, but it may have been divided into cavalry and infantry. Emperor Mingzong of the Later Tang Dynasty completely reorganized the army and made it a truly complete army. In the course of its subsequent development, this army became domineering, and at the same time, another army, known as the Dianqian（殿前军）, was established.In the late Tang Dynasty, the officers of the Fanzhen were divided into three parts. Some of these men became professional officers, some fought as officers, and some did not really run the army. This change had an important impact on the officer system between the Tang and Song Dynasties.
