ISIS drones drop grenades

Elite Iraqi units clearing Mosul from Islamic State occupation face aerial bombardment from modified ISIS drones every day. I just returned from two weeks on the ground inside Mosul with Iraq's Emergency Response Division and the Counter Terrorism Service. These two units are Iraq's best, and are taking the fight to ISIS daily. ISIS is using snipers, suicide car bombs and drones to attack Iraqi forces. ISIS modifies commercial drones to drop 40mm rifle grenades.
