Drenched in sweat, drivers leap into Humvees and tanks to block off access to the main road.Mosul: It only takes a split second for the expression on the Iraqi soldiers face to transform from relaxed contentment to absolute terror.Any soldiers carrying weapons lighter than rocket-propelled grenades scramble into abandoned homes, with some kicking through windows to get inside.It is driving slowly along a main thoroughfare dividing the neighbourhoods east and west, likely looking for a route that could bring it closer to CTS forces.He shakes his head and starts directing the drone back towards his rooftop, sprinkled with broken glass and empty cans of cheap energy drinks guzzled by young fighters."I put the drone up in the sky as soon as I heard there was a suspicious car, but I cant find it," he says, fixated on the birds-eye view of Karkukli displayed on the tablet screen in front of him.Special operations forces have seized the western half of Karkukli from the Islamic State group, but the eastern half -- like most of Mosul -- remains under ISIS control.ISIS has repeatedly turned to suicide car bombings as part of its defence against Iraqi forces since the operation to retake Mosul was launched four weeks ago.The young, clean-shaven soldier is responsible for flying the Mosul Regiments surveillance drone, which has been instrumental in helping them spot incoming car bombs."Im monitoring this area here, as its the only way the car can reach us," Mr Hussein explains, pointing to a deserted main road leading into Karkukli from an adjacent industrial zone. Ill have Hussein set up one (anti-tank missile) for you at the end of the alley," Abbas responds.While the imminent danger has subsided, CTS forces remain on high alert -- the search is on."Grab the bazookas!" one unit leader bellows to his forces, several of whom grab anti-tank missiles and take up positions at intersections where they can spot the car.
