Time to light things up.

what video game is this?

Israeli's Phalanx Close-in air defense system—part of Israel 's "Iron Dome" defense system is shown here successfully engaging incoming missiles from Garza of Lebanon.

In this video, there appear to be at least two high-speed guns out of view of the camera, maybe more. Those guns are at least 50 cal., or perhaps 20 mm, given the range they are achieving.

The white can in the foreground appears to be for close-in fire, in situations where the longer-range guns do not do the job. All the fire power is radar/computer controlled; i.e., there's no human intervention, except to turn the defense system on.

These are actual shoot-downs, rockets probably aimed at Tel Aviv or other populated targets.

Turn your sound up, open the attachment, and watch the action full screen to see and hear cutting-edge technology destroy incoming missiles. It's awesome.
