During the war in Vietnam, a MUST hospital (Medical Unit, Self-Contained, Transportable) was a type of field hospital developed by the US Army. These hospitals utilized inflatable shelters, expandable structures, and auxiliary power units to create self-contained medical facilities. They could be constructed relatively easily and were capable of supporting a large number of patients.
