I've been conscripted into the Covenant armada! Holy shit, they found and conquered Earth already? That shit's not supposed to happen for 250 years, and even then the Master Chief was supposed to stop them.
Well, given that typical, non-augmented humans are probably equal in combat to grunts I guess I'd be frontline cannon fodder. Which sucks balls, but give me a fuel rod cannon and don't require me to breathe methane and we might get along ok.
