The GL5 Active Protection System is an active protection system developed in China by NORINCO designed for main battle tanks. The system can detect incoming warheads such as anti-tank guided missiles (ATGM) with a range of 100m and within a 360-degree horizontal and 20-degree band. Upon detection, two defensive rockets are fired at the incoming threat. The system employs four multi-mission fire control radars for tracking and engaging incoming threats. It is suspected to be installed on Type 99 and VT-4 main battle tanks.[1]
