I've seen some conversation about the space on the shoulder. The angle of the black space, away from the chest seems weird, costume malfunction is plausible but it appears to be seated correctly. My thought was, shoulder strap from the back pack? You can see the back pack strap on the Cpt. here and it does seem to be a substantial strap.
Also, the debate about a cap either not present or grey/silver... Got a few shots.
