DD Did you ever find out the 1 in 5 of those snow posts was concrete my lance carrier use too ,an i would here a satifactory thump as i drove over it , the thing was with the m113 chassis the tracks would grab at the back and sling it upwards , not to good for the 4 tonner behind you lol. Remember setting up an exclusion zone for mating main missile assemblies and warheads together , me and a mate knew that the next lad on stag ( grave yard shift) was **** scared of the dark , so we decided to peel the bark of a tree and smeere the resadue on our faces & hands , which incidentally glowed in the dark, of i went to wake him for stag and rushed back to the trench we both laid in the parapit at the front of the trench, waiting for him to arrive and settle in to his routine , i mean routine, he was having a tug and fag to warm the body up , with our glow in the dark hands a face we leapt up and frightened the lad half to death, we pissed ourselves laughing as he leapt out the trench and shot off into the woods , we didnt see shirley ( his nick name)for about half a day . Never under estimate a squaddies imagination when there bored. good times , could write a book about this stuff
