I would prefer to use US senators who refuse to ratify the Mine Ban Convention. They won't need any particular skills or training, just have them wander around possible UXO sites until they find one with their foot. The great thing about this is, US senators are a 100% renewable resource.
An interesting idea, although I think the US is actually ahead of the curve on mines. From Wikipedia: >> Opponents point out that the Ottawa Convention places no restriction whatsoever on anti-vehicle mines which kill civilians on tractors, on school buses, etc. The position of the United States is that the inhumane nature of landmines stems not from whether they are anti-personnel as opposed to antivehicle but from…
First, they are way easier to detect, as they are bigger and have more metal/explosives to spot.
Also the risk is minimized for the people clearing those mines, if they know they only have to deal with the big ones.
Secondly, it is easier and more practical to mark a field as not save for big vecicles for some time, compared to unsafe for everyone. (schoolbuses usually don't drive through fields)
So yeah, ideally we would not have any kind of mines or war, but we do. And when you want to stop lots of russian tanks for example, I totally would use anti tank mines.
They just won't cripple random children, like the anti person mines will do. And you can clear them out quite easily and safe with just a metal detector and a minimum of training.
But if you have a field with both types of mines, yeah than it is really expensive and dangerous to clear it. And I am amazed by the concept of using rats for help.
And about the self destroying mines - if they would always work like this, it is indeed a big improvement. The concept that they only can go off as long as the battery has power, sounds quite failproof. I remain sceptical though.
