We have not seen any specific images showing the marines that will be in halo 4. We know there will be marines on board the Infinity so they will have a role in the campaign as always. This in an older picture, but i have neglected to notice some details. the guy to the right of chief appears to be smaller than the spartans in the room, and his face is exposed from the front of his helmet(spartans would have visors), and he lacks the amount of distinguishable armor that the other spartans have.
i would assume this is the new look for the marines in halo 4, but i may be wrong. what does averyone think of the new look??
