lead in iraq i would mention two things and one of them is the amount of debris we estimate seven point six million tons of debris and rubble in mosul the next thing would be the complexity of the devices the fact that they are improvised explosives . devices so they don't look like what people would have seen on t.v. and in films it is pressure plate devices to lift devices even passive infrared device and what does that mean i mean how badly they triggered a passive infrared device would be pretty much what you have outside your garage when you're driving home in the evening but it's triggered by movement only so you don't need to touch it you don't need to lift anything it would be triggered by your presence at that so that is extremely dangerous. once the mine is cleared can people to safely return home yes they come once once it's been cleared by by one of our teams if it's critical infrastructure or if it's if it's a house yes absolutely the problem comes when when we're working with debris
