32d Medical Depot was organized in early February and stationed at Phu Bai to provide medical supply throughout I CTZ The second phase involved the deployment of medical units from the continental United States (CONUS) into the Republic of Vietnam (RVN). In March, five medical units arriving in-country were assigned to the 67th Medical Group. These units were the 95th Evacuation Hospital and the 566th Medical Company (Ambulance) stationed at Da Nang, and the 27th Surgical Hospital, 520th Medical Company (Clearing), and the 238th Medical Detachment (KA) stationed at Chu Lai. By the end of April there were 20 brigade units employed in the I CTZ. To provide dental support for the increased number of troops in I CTZ, the 56th Medical Detachment was relocated from Camp Radcliff (near An Khe) to Phu Bai.

This hospital, the 29th Evacuation Hospital, became operational at Can Tho during August 1968 and, together with the 3d Surgical Hospital, already located at Dong Tam, provided hospitalization in the Mekong Delta. The aeromedical capability in this area was doubled with the arrival of the 247th Med­ical Detachment (RA) at Dong Tam in December, joining the 82d Medical Detachment (RA), which had been stationed at Soc Trang since November 1964. At the end of 1968, the alignment of medical services provided efficient, responsive support to the operations of the U.S. Army and ARVN forces in the IV CTZ. In the third phase, measures were taken to refine and realign medical services within Vietnam. In order to ensure a more balanced alignment of evacuation and surgical hospitals in I and II CTZs, the following plan was implemented: The 2d Surgical Hospital would relocate in October 1968 from Chu Lai to Lai Khe The 312th Evacuation Hospital, a mobilized Army Reserve unit scheduled to
