In R. Lee Ermey’s special last night, he offered this defense for the 5.56 mm
When you shoot someone with a 7.62 mm, you kill him and just take one guy out.
When you shoot someone with a 5.56 mm, you wound him and take three guys out, the guy wounded, the medic treating him, and the guy who has to carry him off the battlefield
Sort of an academic exercise, and reminiscent of the horrible “body count” approach that was woefully used in Vietnam (thanks to McNamara and his Whiz Kids), but somewhat interesting
I think a mid size cartridge like the 6.5 or 6.8 would be good for the new carbine
Except the muzzies don’t bother to treat and evac.
Better to just kill them so they don’t wind up in a US court.
I’ve heard that theory before. But I don’t think it rings true in the current battlefield environment because they don’t act like traditional military units in how they treat casualties. It’s not an organized atmosphere. If a dude gets shot he continues to fight most of the time if he is decisively engaged. And I personally am not aware of Shia or Sunni fighters going out of their way to help retrieve wounded comrades. My knowledge of how they fight (I’ve never personally been involved in a firefight) is that they more or less scatter like quail when you start applying effective suppressive firepower, and leave their wounds to the individuals concerned.
