Intense excerpt from the "Pech River Boys" documentary.
Marines Engage Armed Taliban Fighter
Moments after taking fire, U.S. Marines spot an armed Taliban fighter across the Helmand River where the ambush came from. After receiving clearance and confirming that he is in fact armed, the Marines engage with a MK-12, M240b, and M203 grenade launcher. This is a typical engagement for Marines fighting in Afghanistan, and contrary to popular belief confirmation of targets is confirmed before engaging.
