Medical Brigade established its offices and billets at 24/8 Truong Quoc Dung, a group of rented villas in suburban Saigon. The Brigade Headquarters, assigned to the 1st Logistical Command, became operational on 1 May and assumed command and operational control of all medical units assigned to the 1st Logistical Command. Mission and Organization When the advance party of the 44th arrived in Vietnam in March to establish the Medical Brigade (Provisional), the 1st Logistical Command had command and control of those medical units in country which were not organic to divisions, separate brigades, or similar units. The 43d and 68th Medical Groups were the principal subordinate medical commands within the 1st Logistical Command. The Medical Directorate, 1st Logistical Command, was staffed to develop, coordinate, and supervise medical plans and operations, medical supply and maintenance policies, medical statistics and records, professional medical and dental activities, preventive medicine, and medical regulating activities. The Medical Brigade (Provisional) served as a vehicle of transition in transferring the direct command and control of medical support units from the 1st Logistical Command to the 44th Medical Brigade. Colonel Wier continued to direct his staff in the Logistical Command's Medical Directorate while also serving as Brigade Commander. The mission of the Headquarters, Medical Brigade (Provisional) was to "Provide medical service to the United States Army, Vietnam (USARV) through command and control of operating units of the 1st Logistical Command medical service system; developing; [sic] refine and implement operations; reinforce the medical service of the Army divisions, separate brigades and other units having organic medical support, as required; provide staff and technical supervision over religious activities of assigned and attached units; and perform the overall medical service support operations which include patient evacuation, care and treatment; medical supply and maintenance; and the dental, veterinary, preventive medicine and laboratory services." The Brigade Commander was to "Direct the medical service of the 1st Logistical Command and as the Medical Director, 1st Logistical Command is responsible to the Commanding General, 1st Logistical Command for the accomplishment of the overall medical service mission." During the time that the Provisional Brigade was functioning, some of the personnel of the Logistical Command's Medical Directorate were transferred to the Brigade Headquarters; others were transferred elsewhere; and some rotated, so that when the 44th became operational, the only personnel left in the Medical Directorate other than Colonel Wier was a Field Army Support Command (FASCOM) Staff
