"It's not related to aviation and IEDs but the Israelis used to drag fences behind their patrolling jeeps to leave a unique pattern in the ground so anyone crossing it would leave footprints. "

the Russians found that the Afghan fighters would bury mines in the road and then 're-print' the tracks of the vehicles that had previously passed, completely disguising the location of the mine.

Following in the tracks of the previous vehicle, if not immediately afterward, is not a sound technique. There are even mines that wait for the second vehicle to pass before exploding, IOT defeat overpressure mine clearing.

Unless we had a troop and sensor density that would preclude people from emplacing IEDs in anything other than a very hasty manner, we can always expect to find more of these weapons. And it still does nothing to defeat the individual from wanting to employ them.
