This should also apply to our military in combat zones considering these aspects. Although it may seem like a daunting task, the thing to keep in mind is dealing what is real vs what is potential or imaginary. For example, in war we see Military vehicles navigation fields setup by mines. Impossible to de-mine until not under fire and vehicles are left to randomness and good fortune. You could still have a vehicle protected if you could go slightly ahead of time and test the area that you about to transverse. If a tank had a slightly wider skid plate hinged to it's center pivot point that if hit could actually blow the skid to it's direct backwards opposite side upon impact that could through hydraulics put back into it's front position, then you have covered you cross section 100% safely. If that transversed area was marked at the time leaving a trail then the next vehicle that goes through the gauntlet can actually make the path wider.
