The killing fields would never be the same again, thanks to the new-age mine detonating sensors, developed by Omnitech Robotics of Colorado, US. Rollers of a M60A3 Panther tank are fitted with high power sensors to detect an embedded mine from as far as 500 m away, a safe distance from the tank's suspension and chassis. As soon as it is detected by the sensors, a high frequency laser beam is pinpointed on the mine to detonate it. Initial trials have shown remarkable success of the sensors in the mine-strewn warfields of Bosnia ( Popular Science, July '96 ).
