TEHRAN (Fars News Agency)- The Islamic Revolution Guard Corps (IRGC) said its defense troops have launched a new system which brings all movements in the Persian Gulf and the Straight of Hormoz under Iran's online control. The system called 'Hod Hod' (Hoopoe) has been designed by IRGC experts and provides the Iranian troops with the possibility to monitor even the subtlest moves on the surface or in the air.
