Not a lot of details in the article. I'm curious how 'AI' was actually used. Was it used to compensate for wind, distance, etc? Was it used to alert when the target was in range? Was it allowed to automatically recognize the target and deliver a kill shot? Was it used to make sure no innocents were behind him? Why did the apparatus weigh over a ton?

It was only a matter of time before this happened though. With off-the-shelf technology today, even lesser advanced nations, groups and even individuals could put something like this together. Throw in the skills of a more advanced nation, and you get something like this that works from a mile away and effectively destroys all trace of itself before anyone notices. Devices like this could lie in wait for years waiting for the target information to be passed to them. We live in interesting times.
