Notes
Prone rear mount (flattened back control, face-down back mount) occurs when the attacker flattens the bottom player face-down with back control. In wrestling, this is the standard riding position. In BJJ, it creates opportunities for the rear naked choke and collar chokes. (Wrestling coaching manuals; BJJ instructionals)
