About this Unit
The Signal Corps is a specialized branch within many national militaries, responsible for managing military communications and information systems. Established during the American Civil War in 1860, the U.S. Army Signal Corps pioneered the use of visual signaling, telegraphy, and later, radio communications on the battlefield. Over time, the corps expanded its mission to include the development and maintenance of advanced communications technology, ensuring secure and reliable transmission of information. Today, the Signal Corps plays a vital role in modern military operations, supporting command and control through cutting-edge cyber and satellite communications.
