Camilian Princeps have spears(tho anti inf-spears) hastati have swords.

wikipedia sais the hastas were replaced during the polybian reforms but the picture of Imperial legionaries on the site did not really make the article more believeable.

afaik Gaesatae reffers(not translates) to them beeing "spears for hire" spears used as general term for weapons like with celtogermanic infantry : Foreign Spears(tho they actually have spears, if they could afford it they'd have swords but would be called Foreign Spears nontheless.
