If you've ever fired a gun more powerful than a .22, you know immediately this is a BS video. Added: engineering analysis shows that every shot would lift the front end of the dog a little; this then requires time for the platform to restabilize and the camera vision to readjust and be able to acquire targets.Thus limiting the fire rate to single shots. Auto repeated fire would merely be a spray on a jittering platform. The uniform concrete blocks show it's CGI.
