- "You see? Not a demon. A man. Now, we find where he's crawled to die. "
- ―Captain Vinh on the wounded Rambo.
He was portrayed by William Ghent.
Captain Vinh was introduced when Lt. Col. Podovsky arrived at the POW camp, when Podovsky thanked him and asked him to leave one guard. Vinh saluted and left. After Rambo went on a revenge rampage when Co Bao was killed, he murdered Tay with one of his explosive arrows and proceeded to head to a nearby village where he doused a dry wheat field in gasoline. Vinh then made it his priority to go after a furious Rambo after he took out an entire band of Spetsnaz commandos, trailing him to the nearby village. Rambo then killed a chicken and spread its blood around the field to confuse the soldiers and trick them into going deeper into the field, as they thought he was wounded and hiding in the field. Rambo's feint worked, however, and by the time Vinh discovered the dead hen, it was too late. Rambo had already dropped a match from the survival kit of his combat knife into the long grass, causing the entire dry field to rapidly combust. Vinh saw the flames and attempted to evacuate his men from the field but they had ventured too deep into the crop and got lost. With no way out, all of Vinh's men and himself wound up painfully burning to death before they could escape the flames.
