Tour of Duty (1987)

S3E6 A Necessary End

McKay is excited for a date with a stunning blonde, but on their way to the mall, he accidentally hits a child with his jeep. This incident leads him to a makeshift orphanage, where he feels compelled to help the kids. Meanwhile, Doc discovers Purcell under the influence of drugs and grass. Upset, Purcell storms off in search of more drugs, only to find himself arrested and assigned to a lowly "shit burner" detail. Goldman visits Brewster to report a brutal massacre, and later, he and Anderson receive a briefing about a mission in Cambodia aimed at abducting a defecting NVA officer, while Purcell contemplates desertion.
