The price tag for the never-ending, but occasionally paused, war in Afghanistan is well north of a trillion dollars by now. Nearly $US100 million ($132 million) of that is attributable to America's generous decision to buy uniforms for the struggling Afghan National Army -- and a newly released inspector general report says that as much as $US28 million ($37 million) of that cost was tacked on to pay for a proprietary camouflage pattern that Afghanistan's then-minister of defence thought looked cool.
