Where is my -Yoinking!- armour?

I’ve beaten this game at least three times solo on legendary, once on co-op. This piece of -Yoink- has reset me every time. I’ll be that guy, I’ve purchased since the original halo, I preordered the 250 halo 5 pre-order WHERE IS MY -Yoinking!- ARMOUR?! At this point all I have is some bookends and a game.

What armor are you referring to?
