There is no way this is honest or real, i.e., it somehow fought off a tactical unit trying to take the frontline that this drone was holding? Or was it just parked in some area where there was no tactical point of even taking the territory?
Just by virtue of its nature, a single drone and/or a well placed dumb grenade, not even to mention likely a smoke grenade could have easily defeated this thing within seconds of deployment if there was any interest in taking the area this toy was "controlling".
Someone is doing a literal con job to get military graft and fraud contracts.
