User blog comment:Cod1/Spetznaz vs. Marines, who would win?/@comment-1911220-20100603000043

AK-74 is chambered for 5.45x39 and the M16A4 is chambered for 5.56x45 NATO. I was too lazy to put x39 in the first. Since we were on the Ak-74 topic, I just said the cartrige the weapon is chambered for. how is that funny?
