New Army uniform but no new rifle/cartridge?

I believe we are at the end of the capabilities of a kinetic energy weapon unless something very dramatic happens in terms of propellant. A propellant that takes up half the space, gives twice the velocity with half the pressure. Then you will see a new carbine / rifle.

Probably one of the best summations of where we're really at in the small-arms world. Moreso even than cased vs. caseless, the propellant is the issue.
