Funny story from one of my old bosses when he served in Korea...
"Chino" was his nickname, a cool old Mexican guy we all loved to work for. He was assigned to maintain two "quad-50's" mounted on half-tracks. He told us about how they would go out and "shoot all day long in whatever direction they told us to over the radio." Much of his time was spent sweeping 50 cal shells away from the guns and changing overheated barrels with asbestos gloves on.
One day they were out and a guy (enemy soldier) waaaay out from them and ~90 degrees from the direction they were firing would appear, jumping up and down and waving his arms whenever they'd open up with the 50's. Chino, when he wasn't busy, would take pot shots at him with his M1 Carbine, with no effect.
At some point the commander said, "Looks like Chino needs some help, guys." He had one of the two quads train the guns on the enemy's position. Like clockwork, when the other quad opened fire, the guy showed himself and Chino emptied his Carbine - along with four 50 cals. The guy's position erupted in a cloud of dust.
After he stopped firing, the guy on the gun said, "Now THAT'S how we do it, Chino."
Chino replied, "What do you mean "we," gringo? Got a mouse in your pocket? You missed!"
