魏晋南朝存在三类主要的地方护军。一类是以统领若干支军队 ,使它们统一行动为职责的护军 ;一类是随地方都督而置的都督护军 ,既要监视都督的行为 ,执行军法 ,又是都督统军的助手 ;杂号护军的主要职责是管理少数民族及边境地区事务。都护将军的职责应与统领若干军队的护军相同。都护与督护并非同一职官 ,前者是几支军队的统领 ,后者只领一军。 There are three main types of local armies in the Wei, Jin and Southern Dynasties. One is to protect a number of armies led by them to unify their actions as a duty to protect troops; one is with the local captaincy and Dudu Hudu army, it is necessary to monitor the behavior of the captaincy, the implementation of military law, but also an assistant to the army; The main duties of the Armed Forces Nurse are to manage the affairs of ethnic minorities and the border areas. The duty of the general guard should be the same as the military guard of a number of armed forces. Both protect and supervise are not the same officials, the former is the command of several armies, the latter only take the lead.
