 Ukrainian soldiers shoot down Shahad using modernized IGLA manpads. The Air Force command of the Ukrainian Armed Forces demonstrated the successful use of the IGLA man-portable air defense system with thermal imaging equipment against the Shahad. According to sensor media outlet, the video shows the downing of the Shahads with an IGLA manpads and an anti-aircraft missile system from the South Air Command. Thanks to this modernization, the Air Force's mobile fire groups are becoming even more effective at night. The IGLA is a man-portable air defense system developed by the Soviet Union in the 1970s. It succeeded the older Strella III with better range and seeker sensitivity. The system uses a 9M39 surface-to-air missile. It was adopted by the Soviet Army in 1981. This air defense system is known in the West as SA-18 Grouse. The IGLA manpads can engage aircraft and helicopters. Comparing with the Strella series, the IGLA has increased warhead weight. Its infrared guidance system uses proportional convergence logic for target acquisition and movement prediction. Operation of the IGLA is similar to other manpad systems. Firing operation of IGLA involves starting the ground power supply, powering the target acquisition unit and the missile.
