I dunno if it's the real armor but, I know this armor has 20 old than MarkV.
(EDIT: There are one more pic of spartan old armor and OLD Elite Armor from Halo Wars)
(EDIT2: I ADDED MORE PICS)
(EDIT3: 3. As the Halo Wars pagepoints out, they are wear a variation of the MJOLNIR Mark IV Armour, which means that they are probably part of the Spartan-I Program. Kerek 11:52, 16 February 2007 (UTC) `Confirmed by Halo.wikia.com)
