John's chestplate damage?

Wondering if anyone has any Ideas why in most Halo 5 media (Live action, some posters, and merchandise) Chief is missing the chestplate damage on his MK6 armour that he’s had since H3. Does this mean he has had it armour repaired /replaced between the next 72 hours comic and Halo 5?

Yes… at the end of the final arc’s issue, you can even see him walking with his armour and visor repaired.

After the Skirmish on Installation 03 (“The Next 72 Hours”), John-117’s helmet infrastructure had been comprised. Upon returning to Unified Earth Goverment controlled-space, he opted to get his armor repaired, and then respectfully declined an R&R request, on the behest of Fleet Admiral Terrance Hood, ultimately reassigning himself and Spartan Blue Team.

As seen in the Live action trailer Master chief is shot in the left shoulder and chest, such as reference to the marks from the Beta armour and the E3 2013 trailer. So is the live action trailer and it’s basic info going to be in the game?
