eiros is the battle unit of the fleet. navigators pair up with fighters and train on this ship. they can train for years and never leave alpha terran borders, or they can be there for only a few hours before joining a mission to gather information or battle any rogue ships that enter their space. eiros' battle ships are small and fast, but prone to heavy attacks and are weak at the wings. but the navigators and fighters are often well trained and can avoid surprise attacks.
