Footage from a recent Islamic State propaganda video release shows the perspective of one of their 40mm grenade attack drones as well as cutaway footage from the Syrian Democratic Forces on the ground.
The Kurdish SDF fighters can be seen from above, maneuvering but sticking close to cover. They enter a small orchard, and the video cuts to the SDF point of view. They look up to the sky, knowing they are being observed by the quadcopter.
The drone releases the grenade and it explodes near the Kurdish fighters. As the video cuts back to the SDF footage, we can see that they sustained at least two casualties, however the wounds don’t appear to be life-threatening.
