I’m including fracture armor for this, but as of right now, we can’t expect it to be crosscore, but cannon core armor we can.
Helmets=54
Coatings=204 (note that a lot of that is multiple of the same coatings, so it will be cut in half probably)
Helmet attachments=67
Visors=101
Shoulders=69 (lol)
Gloves=22
Knee pads=33
Chests=59
Wrists=13
Utility=22
Total armor combinations possible 308,882,776,553,208.
Or, in simpler words, 309 trillion combinations possible.
That doesn’t include coatings of course
