Are there other ways of getting the Mark VI?

I got my Mark VI in the Spring … legendary visor and all for completing the game on Legendary. Often times while waiting in the lobby, I’ll look at other Spartan’s service records for the heck of it and I’ve noticed so far 2 people wearing the Mark VI helmet who had a “Normal (In Progress)” status for Campaign in their service records.
Are there other ways of getting the Mark VI, or do you suppose their record got reset (happened to me early on, but mine says “Legendary (Completed)”?
Are there alternate ways of getting the Mark VI armor?

There are only 2 ways that I know to unlock it. One is by completing the campaign on Legendary. The other is by less…legitimate means, if you get what I mean.

No. Their service record probably didn’t get it right.
