To earn the International Mine Action Standards Accreditation and be certified for mine action, the rats must pass a blind test, clearing an 800 sq m(8,600 sq ft) field over two days. They must find one 100% of the mines, with only two false positives. So far, 300 rats have been cleared for action. | |
