Marvel Comics Universe and Major X #0 / Major X #6 Spoilers follows.
Major X Expands Uncanny X-Men Mythology As House Of X / Powers Of X Reboot Looms!
I believe the ranks would work out like this (lowest to highest):
- Lieutenant X
- Major X
- Commandant X
- General X
Major X #0 hits stands on August 7, 2019.
However, before that Major X #6 (of 6) hits stands on June 26, 2019.
Plus a tease / spoiler / preview of Major X #6 by Rib Liefeld himself.
Say what you will, this has an entertaining and fun ride so far; popcorn level fun IMHO.
