I looked at an article about that tests.
The 21 of 23 targets were drones, the easiest target to shoot down.
That makes it a little less impressive. But they are looking at a system that can shoot down mortars, artillery, and even cruise missiles.
Yes they were drones but what was the test procedure and conditions for those drones? I would assume they would try to simulate the speed and size to at least have a mark to attain.
