Popular culture: 4077 is widely known as the designation of the 4077th Mobile Army Surgical Hospital (MASH), a fictional U.S. Army MASH unit depicted in the 1970 film MASH and the subsequent television series M*A*S*H (1972–1983), set during the Korean War. The unit serves as the setting for much of the drama and humor, focusing on the medical staff and their routines in a front-line field hospital. The designation has become a cultural shorthand for military medical personnel.

Real-world context: Although MASH stories are fictional, the concept of Mobile Army Surgical Hospitals existed in the U.S. Army during the Korean War and beyond; however, the specific '4077th' unit is a creation of the film and TV franchise rather than a documented real unit.
