Radar O’Reilly left the series in 2019, with the character being killed off in the final episode of Season 15.
In March 2019, Radar O’Reilly was killed off in the final episode of M*A*S*H. The character was played by Gary Burghoff and had been a part of the show since its first episode aired in 1972. Burghoff left after season four, but returned for seasons seven through to twelve. He then left again and didn’t return until season fifteen, when he appeared as a guest star.
Radar was an integral part of M*A*S*H during its run and his death came as a shock to fans. Here’s why Radar left Mash and what happened to him after his final appearance on screen.
Why did Radar leave Mash?
Radar had joined the army at 17 years old, but he never really enjoyed it. He enjoyed playing pranks on people more than he enjoyed fighting and often found himself at odds with authority figures like Frank Burns (Larry Linville) or Major Margaret Houlihan (Loretta Swit). His main role on MASH was as an orderly and he served under Captain B.J Hunnicutt (Mike Farrell), who later became his best friend.
