Now this is hearsay. I would never break the law like this.
But some "scoundrels" in my Hawk unit, about 1973-or 74, in the winter, stole a jeep. They were probably interested in doing something illegal, like consuming Hash, or some other forbidden thing. Anyway, they took off into the great unknown, outside of Schweinfurt, at Area S, (Area Slime) and kinda got lost. They decided to hide the jeep, and drove it into some bushes. It was late December. They parked in a small clearing. Lit up the bowl and heard a crack. Than another. All the sudden, the nose of the M151A1 was pointed up in the sky, and the ass end was under two feet of water! And getting deeper. The scoundrels scrambled out, soaked from head to foot, in below freeing weather. They had parked on a water filled hole used to hide tanks, Hull down. The water froze a few inches thick. Held for a wile, or so I was told.
If not for a passing German M88 rendering a helping hand and tow cable, they might still be there.
