Tonton Streaming Tour of Duty (1987) S1E2 - Notes from the Underground

The VC are mauling the American soldiers through their use of the underground tunnels. On their latest trip into the bush, Anderson and the men provide a blocking force, only the Gooks being driven toward them disappear down into the tunnels... and Goldman and Anderson end up firing on Americans -- thinking they are VC coming toward them. The team ends up in a village but again gets attacked as the VC pop up out the tunnels and then back into them after the attack. Taylor is captured during this fighting -- having been wounded. Taylor ends up being befriended by a VC Doc who has no interest in fighting -- only in returning home alive. On the surface, Anderson and Goldman go into the tunnels, only to end up entombed by a cave-in.
