chunk: Tension arises between Chief and Willard as Willard believes himself to be in command of the PBR while Chief prioritizes other objectives over Willard's secret mission. Slowly making their way upriver, Willard reveals part of his mission to the Chief to assuage the Chief's concerns about why his mission should take precedence. As night falls, the PBR reaches the chaotic last US outpost on the NĂšng River, the Do Long Bridge. Willard and Lance enter the base seeking information on what is upriver. Unable to find anyone in command of the base, Willard orders the Chief to continue upriver as an unseen enemy launches a strike on the bridge.
