Tour of Duty - Season 1 Episode 8 The Good, the Bad and the Dead

A drunken GI steals a chaplain's jeep and goes on a joy ride with a Vietnamese hooker. They nearly collide with a jeep-load of MPs who chase him down. His arrest is witnessed by Zeke, who recognizes him as Decker, his former drill sergeant and role model. Anderson rescues Decker from a certain court-martial (his second) and drafts him into the squad without checking with Goldman first. Decker is popular with the guys but he almost immediately starts to disobey orders. Decker mans a listening post with Horn to watch for enemy troops movements, but he gets drunk and falls asleep. As a result, Horn is nearly killed.
