US Army Signal Corp

The U.S. Army Signal Corps was established in 1860, just before the outbreak of the American Civil War, to provide communications for the Army. Initially employing visual signaling techniques such as flags and torches, the Corps quickly adopted emerging technologies, including the telegraph and later radio communications. Throughout the 20th century, the Signal Corps played a crucial role in every major conflict, from World War I and II to the wars in Korea, Vietnam, and the Middle East, pioneering advancements in military communications, electronics, and radar. Today, the Signal Corps continues to ensure reliable and secure communications across all Army operations worldwide.
