Tour of Duty S01E05 - Sitting Ducks

B Company is sent to relieve another group guarding a small village which is having an important new irrigation system installed. As they arrive, Goldman discovers that the commanding officer has just been killed out on patrol. After they take over, men get hit every time they patrol the surrounding jungle. It looks like someone from the village/fort is setting them up. Horn becomes fascinated with the local Buddhists and eventually discovers that it is the monks using the temple bell, who are tipping off the NVA.
