Looks like it could possibly be an employee of either bungie or 343? idk 
Thats what it appears to be but not sure
I’ve heard of people having codes for the armour, but I have no idea where it came from.

This is possible, although, I don’t think that Bungie is going to be involved in Dev exclusive goodies
Vic Deleon, Kiki Wolfkill, Walshy and some other people have been giving out codes on Twitter. I think they got them from the Halo 4 party at E3.
This little Chief looks cute. 
From E3

I have no idea.
Codes for the Halo 4 Master Chief avatar item were given out at E3. Some codes have also been given out over Twitter and such as little contest or first-come-first-serve items.
I think bs_angel handed some extra ones out after E3.
Alright thanks for telling me. I was really curious how he managed to get that Armour.
