Let's take that lifespan business as an example. The best advertised failure rate for the disarming mechanism I've seen for FASCAM mines is 4%. That's the manufacturer's figure and it's based on optimal conditions. Even if it's true, I don't find it particularly reassuring to know that 1 in 25 land mines will still be live after their expiry date.
I would be even more sceptical of the claim to be able to differentiate between targets. It may well be true that they never detonate when a Challenger passes over them, but I wonder just how many different tractors or school buses they've tried these things out on.
Suppliers of military hardware have a long and distinguished history of over-stating their products' effectiveness, and there's no reason to believe that they've become any more honest recently.

Would you prefer 1 in 25 land mines going off, or 24 in 25 going off? They're not perfect, but they are designed to injure people/blow up vehicles.
They're pretty nasty things in general, but they serve a purpose in war, and you've got to win it before you can worry about whether your kids are going to be walking over them in years to come...
