My friend, the one who is a Halo maniac and has all the Halo books, sayed that the midget aliens are Grunts, the tall ones are Elites, and the ones with the plasma shields are the Jackals. Is this true?
He also told me that the midget ones are not really Covenants and that they work for the Covenants. That is why they wear a gas mask thing, because thay don't breath oxygen. Is this true, too?
