Legio Armatus Ripenses --- 重甲岸防军团 (Legio Armata Ripensis)
Border troops were referred to as limitanei. The law of 325 AD implied that the limitanei consisted of two classes of troops; the ripeness (legions, equites, cunei equitum, and auxilia) and the alae et cohortes. The alae et cohortes included the classis (flotillas). The ripenses or riparienses as they were also called were higher grade troops than the alae et cohortes much like during the principate period.
During the 4th century and even into the early 5th century these troops were still considered battle worthy but were less prestigious than the comitatensis and palatinae units of the field armies.
These troops were permanently stationed along the borders and were usually reluctant to move to another province, though could act in cohort with field armies within their own province or even be promoted to field armies assuming the title of psuedocomitatensis. Over time, however, the limitanei settled down at their posts and became soldier-settlers with families and farms, rather than purely garrison troops.
Although a militia of sorts and treated as second class by the mobile comitatenses, the limitanei are fairly well trained and reasonably well equipped. These milites belong to legionary detachment. Being unarmoured they are more likely to fight in the rear ranks. These milites are armed with veruta and lancea.
边境部队被称为戍边军。公元325年的法律表明了戍边军又包括了两类部队:岸防部队(军团,骑兵,骑兵连,以及辅助部队),alae(我不知道这里的alae该怎么翻译),大队。alae和大队又包括了海军。岸防军,也被称作riparienses,其等级要高于alae和大队,就像是在元首制时期一样。
在四世纪到五世纪初,这些部队依旧被认为具有相当的战斗力,但声望不如机动野战军中的野战军和中央军单位。
这些部队长期驻扎在边境上,但通常不愿意转移到另一个行省,尽管他们可以在自己的省内与野战军共同作战,甚至会被提拔为野战军,并被称为准野战军。然而随着时间推移,戍边军在他们的岗位上定居下来,变为拥有自己的家庭与土地的农兵,而不是纯粹的驻军。
尽管戍边军被机动野战军视为二流部队,但他们还是训练有素,装备精良。这些军人隶属于军团分遣队,在穿戴护甲的情况下,他们更多的是在前线作战。这些士兵装备着长矛与长剑。
