Was that not the case in some other things? I'm sure I remember a story where WY had to effectively bail out the military and them ending up as glorified PMCs?
It was the case in The Rage War books (set in the 27th century).
This, along with WY financing the ICC, is lazy, creatively dull, and has no basis in the source material.
Certain individuals trying to exert influence over the USCM via unofficial means is more interesting and fits with the existing material.
Especially since there were a couple of stories in the works featuring Olivia Shipp that would've explored the USCM and WY being too cozy and how she was instrumental in that changing and making the USCM more independent. Which I think it alluded to in the first issue of the new comics.
