Raider Archers

Summary
Raider Archers (simply called 'Archers' in-game), are a brigade that were used by the Raider faction in-game as a weaker version of regular archers. While Raider Archers still exist in the game files, they don't currently appear in-game under normal circumstances, since the Raider faction was changed in an update to instead draw its brigades from those of the regular factions from which they rebel locally but with penalties to combat performance, rather than having dedicated Raider brigade types.

"Archers are light ranged infantry that have greater range than javelineers, do more damage than slingers, but have very limited melee skills. Archers were relatively rare in combat as the bow was still consider to be primarily for hunting."

- In-game Description

History
Ancient authors frequently describe slingers as being able to outrange archers, at least in European warfare where the stronger composite bow was uncommon. In-game, though, slingers are outranged by archers, likely because archers were designed as a more advanced elite missile unit with better stats as a reward for the extra investment required to unlock them, whereas slingers are a basic missile fodder unit.

Tactics
Raider Archers, though they still have the same range as Etruscan Archers, have diminished damage and defenses in comparison. They are still the strongest among the Raider-only missile units, however.
