Establishment of the Drug Treatment Center, Cam Ranh Bay: A significant change was made in the mission of the 6th Convalescent Center on 15 June 1971, when it became the first operational drug treatment center in Vietnam. The unit was preparing to standdown from its mission as a convalescent center specializing in the care of malaria and hepatitis patients when the new mission was assigned. Because its MTOE was not structured for the drug treatment mission, the new mission necessitated a major reorganization of the 6th Convalescent Center. On 30 October 1971, the 6th Convalescent Center was inactivated and the U.S. Army Drug Treatment Center, Cam Ranh Bay was activated to replace it. The Drug Treatment Center was organized on a TDA specifically structured for the drug treatment mission. Although there were minor organizational problems with the TDA, it proved to be an adequate organizational structure. In addition to the drug treatment mission, the Drug Treatment Center, Cam Ranh Bay was also responsible for area medical support in Military Region II South. For this mission, it had dispensaries located at Cam Ranh Bay South, Nha Trang, Dalat, and the 22d Replacement Battalion.
