The MG-42 was a light machine-gun during World War 2, probably the most famous weapon of them all along with the M1 Garand. The MG-42 had a rate of fire at 1200 rounds per minute (RPM), yet, it couldn't fire such a bullet train, since the barrel will start to melt after a while. This machinegun was the choice of the German machine-gunner, since it causes panic amongst enemy soldiers when fired. It also makes a very distinctive sound, as it was called "Hitler's Buzzsaw".
Third platoon went up the hill, then some kraut fuckhead came out of nowhere and fired his MG-42, wasting every guy in the platoon.
