Signal Corps (United States Army)
The United States Army Signal Corps develops, tests, provides, and manages communications and information systems support for the command and control of combined arms forces. It was established in 1860, the brainchild of United States Army Major Albert J. Myer, and has had an important role from the American Civil War through to the current day. Over its history, it had the initial responsibility for a number of functions and new technologies that are currently managed by other organizations, including military intelligence, weather forecasting, and aviation.
