This is a brief organizational history of a small special-purpose intelligence agency focused on signal equipment used by foreign armies and on the organization and activities of analogous organizations to the US Army Signal Corps in foreign armies. In addition, the Signal Corps Intelligence Agency had been tasked with producing intelligence concerning the Soviet-Bloc civilian power and communications networks.
In the 1950s, the Chief Signal Officer was the head of the US Army Signal Corps which was one of the US Army Technical Services. The Technical Services were bureaus which supplied the army with weapons and equipment, organized and trained special-purpose military units, provided the army with technical services, and managed the careers of officers commissioned in the corresponding branches. The Signal Corps provided communications and photographic services to the army.
