I would guess there is nothing to stop someone carrying a short roll of high density foam (like camping mats) to either sit on or lay down on (prone is a valid position but I doubt it is defined as having to be on your front - just no part of rifle to touch the ground - how is it defined in DE?).
The no-foot-across-the-line rule may cause problems for some as that was changed in the UK some years back to barrel in front + trigger behind ??
