    I recommend Rosy because she's got a machine gun and a healing buff. I'd also recommend you do this in a red (danger) area.

    The raptors are the weakest in the game so your machine gun will tear through them. The way I did this is I went into a danger zone, shot at one of them, and then the other raptors followed.
