Commando Ninja

In 1968, during the Vietnam War, a Special Forces (United States Army) platoon known as the "Lizard Smokers", led by John Hunter, is ambushed by ninjas. In the midst of the chaos, Leeroy Hopkins loses his right arm in the ambush, Sgt. Oskar Kowalsky is attacked by velociraptors, and John is captured by the Viet Cong. While in captivity, John learns the art of ninjutsu from his captor, Colonel Yin. After John's training is completed, Yin sets him free, but warns him of a red ninja who betrayed his teachings. Yin is killed when his compound is bombed by the U.S.
