The layout of the exterior set for filming M*A*S*H 4077.
The series is based on events in the Korean War [June 1950 - July 1953]. Looking at some recent repeats [2024] it has an anti-war theme at times, between the off-duty exploits, and lasted between 1972 & 1983 - almost three times the length of the war it depicted.
