Interesting video but battles like that are a thing of the past. Imagine being presented with multiple hard targets like that on the ground.
That's a commanders wet dream.
... and what happens after the conflict? All that tech just sitting on the battlefield waiting to be picked up and copied/re-purposed.
The R-R getting it at the end seems cool but it would be much easier and cheaper to hit it with a smart weapon from a Drone.
Drones are really were it's at right now.
