The real proof of this stuff is if you were prepared to go out in your inflatable shoes and walk over IEDs yourself.
Sometimes (quite often) all this proves is that the idea was bloody stupid in the first place.
It helps to remember that whilst outlandish ideas sometimes work, usually they don't - it is a common misconception that because 'daft' ideas sometimes pan out that all daft ideas have merit... if this thread were actually intended to generate good ideas for use in Afghanistan then posters might do well to remember a couple of basic 'rules' of the game -
such as
1) We are ostensibly there to support a democratic government, with the overal aim (I presume) of making the Afghan government strong enough to maintain internal security without further support.
2) We are not there to punish the locals, to strip their country of assets, or to damage the Afghan infrastructure (such as it is).
3) They are not an enemy nation that we have conquered, we aren't intentionally in there to kill everyone who looks at us funny.
Consequently good ideas shouldn't involve indiscriminate slaughter of anyone holding a spade, or turning the road network into an allotment.
