Master Chief helmet Mistake?

Just watched the ad, MC doesn’t have a broken helmet. It this because he got a new one, this is before “the next 72 hours”. Thoughts?

I can only assume that the UNSC didn’t have a problem spending the money on a new helmet for the Chief. There’s probably a decent amount of time (several months, if not a couple of years) in between the comic and Halo 5.

He gets it fixed in the comics. Along with the gash on his chest plate. It’s after the “Next 72 Hours”
