No cast member on 'M*A*S*H*' served in the Korean War.

The correct answer is A (True). The TV series M*A*S*H was set during the Korean War (1950-1953), but the show aired from 1972-1983. None of the main cast members actually served in the Korean War, which ended nearly 20 years before the show began filming. Actor Jamie Farr was the only cast member who served in the U.S. military, but he was in the Army during the Korean War era and did not see combat in Korea.
