Friend of mine told me a story of when he drove a tank retriever for the marines, in Vietnam, he was given an order to pick up a broken down tank. When he got to it, the tank was sitting at the base of a hill and the mounted 50 cal was just high enough to peek over top.

As he approached he heard one shot ring out and the guy at the machine gun just sat back. A little while later the guy would aim and fire off another single shot. This happened the whole while my friend was hooking up to the broken down tank, so finally he asked the guy what he was doing.

He looked down and said, climb up and I'll show ya. My friend climbed up on top of the tank and he said, now watch that trail across the river. He said: The first Gook I saw walked down that path to get some water, so I took one shot and blew him to pieces and his body parts went into the woods.

He continued: A little while later, another gook came looking for the first one and I blew him to pieces too, he landed in a pile with the first...My buddy asked him how long he'd been doing this...he told him after 20+ gooks they hadn't caught on to what was happening, they were so far away the shot didn't sound close to them and they were confused.
