Who are the Mercenary types?

I think they're running security for the mission during a time when Weyland doesn't have a weapons division of their own. See how uncreative I can be? LOL!

Well, you never know. You don't see much of them in the trailer though so there's not much to go on. It killing me to find out though. for every possibility that occurs, there's another hundred waiting to spring out at you, lol. I do love the suspense Ridley has built here. In some respect he is a true genius, lol.

I think they use exactly the same spacesuit than the rest of the crew. So they must be in the same team. If the "Prometheus" mission is a cover mission, but is also a very "big" thing, it´s comprehensible that the firm send some security in _ to protect but also to guarantee that nobody starts to have funny ideas like to try to sell the discoveries to rival firms.

actually we see them ...the 2 with pistols firing are quite surely mercenaries ...

nice. a theory thread that isn't retarded. that totally makes sense. though it's possible they might be pmc type running security detail. scott liked exploring how current events might translate to the future. pmc certainly will have a place in the future when warfare possibly becomes totally corporate.
