That's the Chris Martenson video. It's nonsense. He misidentifies shots and makes unsupported claims about who is shooting where.
I agree that Chris Martenson made some mistakes. Though what where the hollow sounding shots from? I didn’t hear a crack(bullet passing camera) with them. USSS sniper team three near the southern end of the area I’ve not heard any reports if they fired their weapons. I know Team one the team most seen in video never fired a shot. Team two fired one shot that I know of which did kill Crooks
