All covenant are flood. The reason only Elites and Marines are Combat forms is because they are the only ones who can handle it. Grunts are too weak for flood fighting, so they become carrier forms. Hunters can't be infected at all, because they aren't whole beings, just colonies of spineless worms. That's why they have all the armor, to hold their shape together.
