The entire report, on SkyNews, has the byline of Major Chris Hunter, “former [UK?] special forces bomb technician”:
…The shocking footage of the improvised fighter jet rocket demonstrated the ISIS instructors advanced understanding of every part of the missile’s highly intricate array of components.
Terrifyingly, those components: the seeker unit, infra-red homing radar, and all the other complex avionics that control the missile and its deadly explosive payload, had all been modified to turn the obsolete munition into a deadly remote controlled surface to air missile that could be fired against a range of aircraft such as helicopters, low flying jets and unmanned aerial vehicles.
The ability to reverse engineer and modify advanced weapons of this type, is something no terrorist group has ever achieved…
The tone is typically (journalistically) alarmist. To all our SD special force people, bomb technicians, engineers, terrorists, and their armchair followers: are the skill sets here truly higher than the Taliban, al-Queda, Hamas or Hizbollah, for example, that we’ve seen? (Of course, they have Iran as a military supplier when it sees fit, so the situation is different.)
