There is an aircraft that the Taliban fears more than any other. The drone of the engines instills a great sense of fear and sends them scrambling in all directions and for very good reason. Unlike some fighter jets or attack helicopters it can rain hell on them for an extended duration. Additionally the presence of this aircraft foreshadows a nearby special operations unit that is closing in on the Taliban fights. The aircraft is the AC130 Gunship. The variations have changed through out the years with newer aircraft being outfitted with the new 30mm bushmaster and hellfire missile pods. One weapon has remained constant the 105mm. Which seems to be the primary weapon used in this video to dispatch the jihadi fucktards in no time at all.
The video below provides a closer look at the weapons systems across the different Gunships.
