Whats up with the mix-matched armor sets in Halo 4? One is olive drab metallic armor with a face mask, another is mostly white and appears to be made out of more fabric like material and the other one is the same thing as the white except for the fact that it is black? (ODST's Maybe)

Infinity is a mix N'match of navy, marines and air force, the only actual marine uniforms are the olive green one with the Helmet, the one with the Radio (also olive green) and the medic (white with red stripes) that Conan was using in the easter egg.
