There are army promo videos that show all kinds of crazy, dangerous, incredible stuff, but those are produced by people who have millions on the line.

When they show them in the past, it is very difficult to see what actually happens. You occasionally get a puff of smoke on the ground when a ball hits something, but you have no idea what the coverage is or how dense it is.

There are 180,000 balls that go flying.

This video shows them in a half circle because there's water to splash when they hit, but you know that everything else in the rest of the complete circle has been shredded. This is pontoon bridge building in the distance. No visible people.

The moment I am describing is at 7:11. A magical number.
