The United States Army Signal Corps (USASC) is a division of the Department of the Army that creates and manages communications and information systems for the command and control of combined arms forces. It was established in 1860. In 1942 General George C. Marshall ordered the creation of the Army Pictorial Service (APS) to produce motion pictures for the training, indoctrination, and entertainment of the American forces and their Allies. The APS produced over 2,500 films during the war.—Wikipedia
The Marine Raiders were elite units established by the United States Marine Corps during World War II to conduct special amphibious light infantry warfare, particularly in landing in rubber boats and operating behind the lines. "Edson's" Raiders of 1st Marine Raiders Battalion and "Carlson's" Raiders of 2nd Marine Raiders Battalion are said to be the first United States special operations forces to form and see combat in World War II.—Wikipedia
Airborne forces are military units set up to be moved by aircraft and "dropped" into battle, typically by parachute. Thus, they can be placed behind enemy lines, and have the capability to deploy almost anywhere with little warning. The 82nd Airborne Division is an airborne infantry division of the United States Army, specializing in parachute assault operations. It was organized in August 1917 originally as the 82nd Division of the United States Army and served with distinction on the Western Front in the final months of World War I. Since its initial members came from all 48 states, the division acquired the nickname All-American, which is the basis for its famed "AA" shoulder patch. The division later served in World War II where, in August 1942, it was reconstituted as the first airborne division of the U.S. Army and fought in numerous campaigns during the war.—Wikipedia
