It’s going to be decades before that happens, and by then the Boston Dynamics Murderbot 3000s will have replaced troops anyways

Damn, Foucault got hands

A “benefit” though could be that you’ll have less dead people from shootings with these and more injured. The round is substantial, but it penetrates more than anything. The reason the 5.56 is so lethal isn’t because of penetration, it’s because it tumbles when it hits human bodies and becomes a much more dangerous object compared to rounds from a handgun that fire clean through. It’s horrible to have to have a conversation about it, but I haven’t seen much testing from the 6.8mm or even much on the slight smaller creedmore on that aspect of it (tumbling).

There have been opinion articles by people with no sway on the matter, but I haven’t seen anything from any official source or from anyone in a position to make a difference.

The transition into 6.8mm is very soft. So far, the US Army is the only US military branch adopting 6.8mm, and even then it is being phased into units most likely to be engaged in spearheading fights. So far the Rangers, Special Forces, and 101st Airborne have been seen training with XM7s and XM250s. I’d expect 82nd Airborne to also be high on the list, seeing that they are on the Immediate Response Force. After that other infantry units and units that would work closely with them, but for now it appears the majority of the Army is keeping 5.56mm.

I think it is a true unknown if 6.8mm ends up pushing out 5.56mm as the US standard. Really it depends on what the world looks like if it ends up becoming a staple cartridge or a flash in the pan. If the US really adopts it wholesale, I think you’ll then start seeing NATO countries adopt it.
