U. S. Army Signal Corps

The U.S. Army Signal Corps was established in 1860, just before the outbreak of the Civil War, to manage military communications. Throughout its history, the Signal Corps has pioneered advancements in communication technology, from wigwag flags and telegraphs during the Civil War to modern satellite systems. The Corps played crucial roles in both World Wars, developing radio, radar, and cryptographic systems that greatly enhanced battlefield coordination. Today, the Signal Corps continues to ensure secure and reliable communications for the Army, adapting to the challenges of cyber warfare and digital information dominance.
