Do we know how all the armors are unlocked?

Games Other Halo

I know that some are unlocked through specializations, and others are by completing certain tasks/challenges. Can you also buy armor with XP?

I know I saw a picture recently with some of them being for the specs and I know you get raider for getting all terminals. THen Mark helm is for beating campaign on legendary.
Then deadeye and locus are pre orders only AT THE MOMENT and FOTUS is LE only.
A lot of the rest are just for leveling up in SR.
