This video was actually made by the bad guys. The cameraman is filming his friend as he praises Allah and launches mortar rounds at American troops. The shooter apparently knows nothing of the latest American shell tracking technology which can track the trajectory of a hostile round and fire a retaliatory round to precisely where the hostile round was fired from. This technology requires only a few rounds to zero in. Notice that the shooter has just chambered his 4th round when he is recycled to Allah.
