because it is the halo 2 hand. notice the 5 dots instead of the new spartan's 3 dots. this can only mean two things. one that bungie overlooked the fact to make all spartans alike for the screenshots(unlikely) or that there is another spartan in the mix. we somehow need to steel the bungie halo bible and find out. or read the third installment of the halo book series, or wait for halo 3 [Edited on 12/3/2006]
