yes
There is no way to get and different armor for Elites in the BETA.
Not that anyone is aware of, 343 Industries may release DLC containing armor for Sangheli's (Elites).
Choose the gamemode Slayer (Not Classic Slayer) and play that one, or choose invasion, to play Spartans against elites, or choose infection, for Spartans and elites to fight infected Spartans and elites. there may be other ways, but they are not yet known.
Yes
You can't be a hunter only Spartans or elites sorry it would be fun though
No, but there is a limited edition elite armor that comes with it.
Spartans are generally 7 feet without there armor. In full armor they can be as tall as 8 feet.
the halo reach legendary edition comes with extra armour for Spartans and elites as well as a model of Nobel squad
There are no colors for Elites in halo reach, that is because the colors you used for the Spartan species will be used for your Elite species, and the same thing occurring for the Emblem and everything else!
Because they -the Elites- are taking over Reach, and you are trying to stop them. This is rather confusing to many people as they were allied with the UNSC in previous Halo games, but keep in mind that Halo: Reach is set before even the first Halo game, Halo: Combat Evolved.
Helmets Jun:scout kat:air assalt jorge:grenadier carter:mrk v(b) emile:e.v.a Jorge had mark IV armor but all the other Spartans had mark V armor with several different modifications.
Why yes they can if the game glitches somehow... Or they use there MLG LEGITZZZ Powers to use them.
