Archer Auxilia are a type of infantry unit in Rome: Total War and Total War: Rome Remastered.
Description[]
Archer auxilia are supporting troops for the heavier legionary infantry, an important secondary role in Roman warfare. They are not expected to fight in hand-to-hand combat and are not given the war gear to do so for long; their job is to provide supporting fire and let the legionaries fight the main battle. Because the Roman army is standardised around its heavy infantry legionaries other types of troops are recruited as auxiliaries. Their training is very nearly as vigorous as that of the legionaries and discipline in auxilia units is certainly as harsh and uncompromising.
Historically, with the changes introduced by Gaius Marius professional auxiliaries were recruited to serve alongside the now-professional legionaries; a wholesale shake-up of the Roman military machine saw the whole army being put on a full time, service-for-life footing, with auxiliaries being rewarded with Roman citizenship at the end of their military careers.
