Surgeon General of the United States Air Force
In September 1947 the combat elements of the Army Air Forces separated from the U.S. Army, forming the United States Air Force. But a few Air Force support functions, such as medical care, remained U.S. Army responsibilities for the next two years. Starting in 1948, the Air Force and the Air Surgeon, Maj. Gen. Malcolm C. Grow (1887-1960), began to convince the U.S. Army and the administration of President Harry S. Truman that the Air Force needed its own medical service. In the summer of 1949, Air Force General Order No. 35 established a medical service with the following officer personnel components: Medical Corps, Dental Corps, Veterinary Corps, Medical Service Corps, Air Force Nurse Corps, and Women’s Medical Specialist Corps.
Militia
The Militia Act of 1903 divided what had been the militia into what it termed the "organized" militia, created from portions of the former state guards to become state National Guard units, and the "unorganized" militia consisting of all males from ages 17 to 45, with the exception of certain officials and others, which is codified in . Some states, such as Texas, California, and Ohio, created separate state defense forces for assistance in local emergencies. Congress later established a system of "dual enlistment" for the National Guard, so that anyone who enlisted in the National Guard also enlisted in the U.S. Army. When the U.S. Air Force was established as an independent service in 1947, the National Guard was further divided into the Army National Guard and the Air National Guard. Under this construct, the 1933 defense act's "dual enlistment" facet was further amended so that enlisted soldiers and commissioned officers in the Army National Guard were also enlisted or commissioned in the Reserve Component of the U.S. Army. Enlisted airmen and commissioned officers in the Air National Guard were also enlisted or commissioned in the Air Reserve Component (ARC) of the U.S. Air Force.
