Well as the article said, M81 was tied mostly to the advisory role they played with Afghan forces. As this has apperently mostly gone away I can see MC being adopted simply to streamline MARSOC and other non NSW SF. Let the navy have their stuff as they already have a lot invested and have MARSOC adopt MC. Let M81 finally retire with dignity.
Now if only RHS could make a decent G3 uniform in MC and make it not literally glow. That would be lovely.
