It’s called Autonomous Rotorcraft Sniper System. And it mounts a powerful rifle onto highly stabilized turret, and fixes the package on board a Vigilante unmanned helicopter.
The system is intended for the urban battlefield — an eye in the sky that can stare down concrete canyons, and blink out targets with extreme precision. Attempting to return fire against the ARSS is liable to be a near-suicidal act; ARSS is described as being able to fire seven to ten aimed shots per minute, and it’s unlikely to miss.
