Armored vehicle math 101:
Below freezing temps + semi immovable objects + drivers cloak of invincibility because he's surrounded by steel = eventually being put afoot
This reminds me of two actual events when I was in the Armored Cav. The first was going downhill at top speed through a grove of frozen fir saplings In an M551 Sheridan. When we got to the bottom of the hill and out into the open-- we looked like a porcupine-- the thin shell of the outer skin of the tank was punctured by limbs in several places, with the stripped limbs sticking out in all directions. We repaired the damage with the bottoms of #10 cans from the mess hall-- but our Sheridan had all these circular patches, definitely making it look distinctive.
The second event was when we had an M113 driver who thought he could "jump" a 12 foot frozen stream in Germany during a particularly cold winter. He thought if he got up enough speed and distance he could make the jump, but the two "itys" overtook him-- insanity and gravity. It took the horsepower of two Sheridans and an M113 hooked together to extract the offending M113 from the opposite bank of the stream. Staying dry while doing so in sub freezing weather was not possible. Both final drives were sheared, and the driver lost his front teeth. Armored vehicle accidents are always a big problem.
