regular rifle or super/future-y one?
Joanna: *nods* Tell me, where those things you fought before her any challenge?

Probably a future-y/uber one. Solty Rei definitely falls into the Sci-Fi genre, among other things.
Speaking of Uber... The most powerful units in Halo Wars (Scarab for Covenant and Vulture [I think it was Vulture] for Marines) are literally called "Uber Units" in-game.
