Wasn't there a Tank Crew found dead under their tank in RAFG that sank onto them in the night crushing them?
I was in the RAF but working with 24 Brigade (604 FACS). It was forbidden for anyone to sleep underneath a vehicle for that precise reason.
After several army types were killed when lying, camouflaged, in ambush position the powers that be stated that a notice on a 6ft pole was to be posted next to camouflaged ambush positions, the notice was to say "DANGER! |Troops are hidden within 4 metres of this notice". Soon after a German army tank crushed several troops despite the presence of the notice. The tank commander's excuse was the had to get closer to the notice so that he could read it.
