IIRemusII: If they're overused in this forum then i didn't know bc I never come to the library. But they weren't a failure. They were used on suicide missions in which they accomplished their goals, along with dying.
I recall several SPARTAN-III's surviving and completing their objective, so the others failed, which were 95% of them. The project failed.
Noc, I said Spartans in general. IIIs are used, too, you know.
