The MASH unit was conceived by Michael E. DeBakey and other surgical consultants as the Mobile Auxiliary Surgical Hospital. It was an alternative to the system of portable surgical hospitals, field hospitals, and general hospitals used during World War II. It was designed to get experienced personnel closer to the front, so that the wounded could be treated sooner and with greater success.
The idea made its way into popular culture through a film and television show.
