When I was in Bosnia, the ROE called for a warning shot. When we did our convoy brief every morning before rolling out for a mission, the team sergeant always briefed that the warning shot would be aimed COM, and the real shot would be aimed at the spot where the BG was lying on the ground bleeding. Best convoy briefs I ever got.
"If ye love wealth better than liberty, the tranquility of servitude than the animated contest of freedom, go from us in peace. We ask not your counsels or arms. Crouch down and lick the hands which feed you. May your chains sit lightly upon you, and may posterity forget that you were our countrymen!” - Samuel Adams
