The South African Military Health Service is the branch of the South African National Defence Force responsible for medical facilities and the training and deployment of all medical personnel within the force. Though unusual, as most national militaries integrate their medical structures into their existing service branches, the SANDF regards this structure as being the most efficient method of providing care and support to the SANDF's personnel. It is a significant actor in the effort to control HIV/AIDS within the SANDF. History The predecessor of the SAMHS, the South African Medical Service, was established as a full service branch of the South African Defence Force (SADF) on 1 July 1979 in order to consolidate and strengthen the medical services of the South African Army, South African Navy and South African Air Force. Rationalisation Following the end of the Border War, in the early 1990s, it implemented several retrenchment measures. It consolidated all quartermaster stores in the Cape Town and Bloemfontein areas, relocated its training center from Potchefstroom to Pretoria, closed several medical supply depots, consolidated computer centers and systems, rationalized procedures for procuring medicine and medical equipment, discontinued survival training, and reduced or closed sickbays and military medical clinics that served other armed services affected by retrenchments. The SAMS was incorporated into the South African National Defence Force on 27 April 1994, and was renamed the South African Military Health Service on 1 June 1998. Organisational structure The SAMHS includes active duty military personnel and civilian employees of the Department of Defence. In addition, the service employs roughly 400 medical doctors and private medical specialists are sometimes appointed to supplement the staff of the SAMHS. The Surgeon General heads the SAMHS and has the rank of Lieutenant-General. The SAMHS operates three Military Hospitals; one in Pretoria, one in Cape Town and one in Bloemfontein. There are also four specialized institutes - the Institute for Aviation Medicine, the Institute for Maritime Medicine, the Military Veterinary Institute and the Military Psychological Institute. Together, these units provide comprehensive medical care for military personnel and their dependents, as well as the police and employees of other security-related government departments, and occasionally to neighboring countries. The SAMHS also provides extensive veterinary services for animals (mainly horses and dogs) used by the security and correctional services. The Institute for Aviation Medicine and the Institute for Maritime Medicine screen pilot candidates for the air force and for
