Talking about A-10s, I was at a firepower demo on Salisbury Plain some years ago and the pongoes, who were more used to seeing Harriers and Jaguars strafing at comparatively short range, erected the seating in the usual place for us visitors to get a good view of the aircraft firing and their results. A pair of A-10s pitched up and did all of their firing some considerable distance behind us, so we missed the most exciting bits. The results were impressive, though. That's the GAU-7 for you.
