"...the US discovered that various potential enemies have been quietly enhancing their own small arms capabilities and are on the verge of achieving overmatch.

There has been no specific information on what the evolved threat is, but it appears that the Chinese and Russians are about to field improved ranges of weapons and ammunition."

Maybe there really is a 6.5 Grendelski???

What have the Chinese and Russian been migrating towards? I think that the Chinese have a 5.8mm in a bullpup.
