Yeah, that doesn't look like a Super MAC Orbital Cannon.
Look alot like a Frigate, since it has an engine.
If you really memorised the books, you'd remember the Class II Spartan II were canceled, due to lack of funding.
That's why they made Spartan IIIs, cheap(er) but effective soldiers.
All of these theories were brought up before, and most were proven wrong.
Yeah, that could be James, as brought up many times before, but he is most likely dead. If he isn't, then why wouldn't they tell anyone? How could they retrieve his body in that battle?
