A highly classified unit of the US Army, the Intelligence assistance Activity (ISA), focuses on gathering intelligence, infiltrating targets, and aiding for special operations while utilizing cutting-edge tactics and specialized tools.
The Intelligence Support Activity (ISA), also known as the 1st Capabilities Integration Group (Airborne) or The Activity, is a component of the US Army and serves as a dedicated intelligence group for the Joint Special Operations Command (JSOC). Unlike other special operations forces, the ISA focuses on secretive and clandestine actions to support military operations rather than direct combat. Its main purpose is to gather human intelligence (HUMINT) and signals intelligence (SIGINT) in support of JSOC and other intelligence agencies. The ISA has a long history, starting as the Field Operations Group (FOG) and later expanding after the failed Operation Eagle Claw. The organization comprises different elements, including administration, training, SIGINT, HUMINT, and direct action. The ISA conducts intelligence gathering, infiltration, and intelligence support operations, using advanced tradecraft and specialized equipment. Some notable operations of the ISA include Operation Winter Harvest, Operation Queens Hunter, and its involvement in Operation Anaconda and the hunt for Saddam Hussein. The exact details of the ISA’s operations and equipment are classified, but it is known that the unit employs a range of weapons and specialized tools for intelligence collection.
