2-2-3 is one of the most deadly rounds there is. It disintegrates when it hits you and opens up because they wanted to kill more people and maim more people in Vietnam. And so they had to have full metal jacket under the Geneva Convention. So they made a full metal jacket hyper-velocity round that breaks up when it hits bone. It's basically a fragmentation kinetic weapon. Any bullets a kinetic weapon, but it's a fragmentation kinetic weapon that gets around the Geneva Convention.
