The SAMHS is organized into regional medical commands, corresponding to the army's regional commands, as well as a Medical Logistics Command and a Medical Training Command. The regional commands support military units, military base hospitals, and military unit sickbays in their region. The Medical Logistics Command is responsible for medical logistics only, as each service provides for its own logistics support. In addition, the Medical Training Command supervises the South African Medical Service College, the South African Military Health Service Nursing College, and the South African Military Health Service Training Centre, as well as the military hospitals' training programs. The nursing college, in Pretoria, grants a four-year nursing diploma in association with the University of South Africa. Specialized, in-service training courses for nurses and for nursing assistants are also available.
