Just based on a quick look I think the point of this one is the follow ability, and plotting a path through complex obstacles.
The original Big dog might have been quite a few years ago but since then they've had: big dog no cables big dog on petrol engine big dog that runs 30mph big dog massive payload carrying big dog that won't fall over / rough terrain big dog on batteries that follows you automatically. next: big dog with gun/s?
I guess when they put it all together, that thing's gonna be amazing. And No you won't see a youtube vid of it. One day the yanks will just "unleash the hounds" on the battlefield.
