During the American Civil War, Surgeon (Major) Jonathan Letterman, Medical Director of the Army of the Potomac, realized a need for an integrated medical treatment and evacuation system, equipped with dedicated vehicles, organizations, facilities, and personnel. The Letterman plan was first implemented in September 1862 at the Battle of Antietam, Maryland. The United States Army's need for medical and scientific specialty officers to support combat operations resulted in the creation of two temporary components: the U.S. Army Ambulance Service, established on June 23, 1917, and the Sanitary Corps, established on June 30, 1917. Officers of the Sanitary Corps served in medical logistics, hospital administration, patient administration, resource management, x-ray, laboratory engineering, physical reconstruction, gas defense, and venereal disease control. They were dedicated members of the medical team that enabled American generals to concentrate on enemy threats rather than epidemic threats. On August 4, 1947, Congress created the Navy Medical Service Corps. In the United States, a report entitled "Accidental Death and Disability: The Neglected Disease of Modern Society (1966)", was published by National Academy of Sciences and the National Research Council. Better known as "The White Paper" to emergency providers, it revealed that soldiers who were seriously wounded on the battlefields of Vietnam had a better survival rate than those individuals who were seriously injured in motor vehicle accidents on California freeways. Early research attributed these differences in outcome to a number of factors, including comprehensive trauma care, rapid transport to designated trauma facilities, and a new type of medical corpsman, one who was trained to perform certain critical advanced medical procedures such as fluid replacement and airway management, which allowed the victim to survive the journey to definitive care. The International Committee of the Red Cross, a private humanitarian institution based in Switzerland, provided the first official symbol for medical personnel. The first Geneva convention, originally called for "Amelioration of the Condition of the Wounded and Sick in Armed Forces in the Field", officially adopted the red cross on a field of white as the identifying emblem. This symbol was meant to signify to enemy combatants that the medic qualifies as a non-combatant, at least while providing medical care. Islamic countries use a Red Crescent instead. During the 1876–1878 war between Russia and Turkey, the Ottoman Empire declared that it would use a red crescent instead of a red cross as its emblem, although it agreed to respect the red cross used by the other side. Although these symbols were officially sponsored by the International Federation of Red Cross and Red Crescent Societies, the Magen David Adom (Red Star of David, MDA), Israel's emergency relief service, used the Magen David (a red star of David on a white background).
