The present review is dedicated to organization and principles of operation of the Medical service of the Armed Forces of Great Britain. At the beginning of the review a brief description of British Armed Forces and their medical service is presented. Then the particular key elements of the medical service such as the medical services of the Armed Forces major components, inpatient care, medical supplies, research, medical care at an operation theater, medical personnel training are considered. The special attention is paid to the Joint Medical Command formed four years ago as a prototype for the future integration and centralization of the whole medical service. The cooperation with the civil health care has played an increasing role in the organization of British military medicine. That is why the review includes the short description of the major structure of the British civil health care system--the National Health Service.
