To be honest, I'm not too impressed with that system. It's profile is too high, and if you look at the videos of it's targeting, it bounces all over the place. I cannot go into detail, but I have worked on stuff 30 years ago that was more stable than this. Lord only knows where it's at now. They were doing over the horizon back then and this thing, even under remote, is line of sight? These systems use nothing new, a servo drive/control system, which is basically stepper motors which can react blazing fast and in whatever increments you build the stepper motor to, and the gear you attach it too. The gearing allows for the weight, while a stepper motor can looking like a free spinning high speed motor, but stop instantly, using electronic braking to hold it's position, then move incrementally. The heat signature, never mind the radar signature, will make this the first target of opportunity. I believe they are designed more with civilian control than real defense, or maybe counter terrorists, but I would not want to be in a closed in situation with such a device, a can of paint will knock it out of commission, as would a well dropped steel weighted blanket. The Afghani's we knocking Hind's out of the air with boulders hitting the rotor systems, when they suckered the Helos into canyons, and these things are being mounted on trucks? On way to mission, before being a 1/2 mile out of the complex, a WWII vintage anti-tank gun could take out the optics with one shot. This is putting all your eggs in one basket. I guess the the source is more of interest than the actual gun. PKK watch out.
