First Radio Relay

• Origins in WWII: The concept of radio relay units originated during World War II to enable long-range, secure communications between forward units and headquarters over difficult terrain. • First in Korea: The U.S. Army's First Radio Relay Company was officially activated in 1950, just before the outbreak of the Korean War, and played a critical role in connecting battlefield units. • Microwave Innovation: The unit pioneered the use of microwave radio relay systems, which allowed for high-capacity communication links over long distances without relying on vulnerable cable lines. • Critical in Inchon: During the Inchon landings in 1950, First Radio Relay provided vital communications between command ships and landing forces, contributing to operational success. • Cold War Deployments: After Korea, the unit was often deployed to NATO countries in Europe, where it established relay links to counteract Soviet jamming and maintain secure communications. • Vietnam War Service: In Vietnam, First Radio Relay supported tactical operations by ensuring reliable communications across jungles and mountainous terrain, often under fire. • Technological Evolution: The unit transitioned from bulky, truck-mounted relay equipment to more portable and robust systems, adapting to the needs of modern, mobile warfare. • Decorations and Honors: First Radio Relay units have received numerous commendations and campaign streamers, reflecting their critical yet often unsung role in military operations. • Disaster Relief: Beyond combat, First Radio Relay has provided emergency communications in disaster zones, such as after typhoons and earthquakes, supporting rescue and recovery efforts. • Legacy of Innovation: The expertise and traditions of First Radio Relay live on in today’s Signal and Communications units, whose secure, rapid communications are essential on modern battlefields.
