The game begins in Saigon 1967. A transport plane full of fresh recruits landed and soldiers dismounted from it. Two soldiers, Privates Jack Kowalski and Caleb "Cal" Walker were picked by a CO to join an air assault to overrun a VC camp near Kontum with their new squad. The soldiers later seized the camp and occupied it with the rest of the company and converted it into American basecamp. The base became popular among the marines.
The group then takes on many missions from clearing out villages from VC and search for any weapon cache. They jumped to the next task of seizing an old French fort and defend it from the Viet Cong. As the game progresses, the group member began to die one by one in various missions to come. New soldiers are later introduced and Walker joins special forces. They take on subversive, rescue, and assault missions. Cal's final mission is to defeat General Diem, the game's main antagonist. He succeded and delivered the general's head to the base.
The game ends with only Walker and another ARVN soldier named "Monty" survived the group and the rest of the group were dead following a massive joint NVA and VC attack to the basecamp. Walker ends his tour of duty and continues a second tour of duty with his own special operations squad.
