provided adequate medical coverage without an overlap or duplication of medical resources. An additional objective was to obtain a clearer visualization of the manner in which the medical service functioned at each of the major logistical bases. The following 19 bases were selected by the brigade headquarters to be surveyed by medical groups responsible for medical care in their areas: 43d Medical Group Cam Ranh Bay Nha Trang Tuy Hoa Phan Rang 55th Medical Group Qui Nhon Pleiku 67th Medical Group Chu Lai Da Nang Phu Bai Camp Evans 68th Medical Group Long Binh Vung Tau Saigon/Cholon/Tan Son Nhut Cu Chi Can Tho Bien Hoa Lai Khe Bear Cat Long Giao The groups were not allowed to delegate responsibility for the conduct of the surveys to subordinate units. A detailed format was developed for the groups to utilize in documenting the results of each survey. This format, along with the requirement that the group headquarters conduct the surveys insured both comprehensiveness and standardization. Every aspect of medical support at a given base was required to be surveyed, to include preventive medicine, evacuation, hospitalization, laboratory service, dental service, veterinary service and dispensary service. At the end of 1968, the first two surveys had been completed and forwarded to Headquarters, USARV. Medical Regulating During 1968, The mission of the Medical Regulating Office continued to be the control of patient evacuation within and out of the Republic of Vietnam. Accumulation of daily medical statistics for medical regulating purposes remained a function of the office. The Medical Record Statistics Division, USARV Surgeon's Office continued to function as the primary agency for medical records and reports. The importance of having a responsive medical regulating system was dramatically demonstrated during both the Tet Offensive and the May Offensive. During February and May, close coordination with the U.S. Air Force aeromedical evacuation team was necessary to preclude over­loads at the casualty staging flights and to arrange additional special flights, which in some cases originated at alternate air­ fields not normally used for out-of-country evacuations. The support and cooperation of the U.S. Air Force played an extremely important role in the successful operation of the 44th Medical Brigade's medical regulating system. In early 1968, there were few scheduled in-country and out-of-country flights available which limited evacuation and created the need for nonscheduled special flights. Shortly after the Tet Offensive, the number of scheduled in-country flights by the 903d
