surgeons lacked the skills and experience necessary to meet the demands on the units, as Carroll often sent younger, less experienced surgeons forward, a departure from the Army's experience in World War I, which showed that less experienced surgeons should be kept at larger facilities to the rear, where they could operate under the tutelage of a more experienced senior staff surgeon. And, finally, the Portable Surgical Hospitals had been stripped so lean that they were never truly self-sufficient, and had to rely on other units for life-support. The Mobile Army Surgical Hospital, developed after World War II, would address these concerns. One-hundred percent mobile with organic vehicles, with 60 beds and assigned nurses, and fully equipped and supplied to provide definitive care, the MASH built on the experiences of the PSHs of World War II.
