My favorite, true RPG story. I used to work with a young man from the Balkans. During the war, one of his good friends was pressed into military service. While on guard duty at a small shack near the barracks, the lad came under attack. It being the greenhorn's first combat experience, he nervously shouldered his RPG, took aim and fired the warhead - straight back at the barracks where he scored a direct hit. Seems in his haste he neglected to notice it was backwards. Fortunately, for him and and his comrades, the barracks had emptied by then.
