The most secret of secret units
With the spotlight shining brightly on the Joint Special Operations Command, several of its component units have receded further into the shadows.

Intelligence Support Activity
The United States Army Intelligence Support Activity (USAISA), frequently shortened to Intelligence Support Activity, or Mission Support Activity, nicknamed The Activity, the Army of Northern Virginia,[1] or Office of Military Support, and operationally known as Task Force Orange,[2][3][4] or less often Task Force Mandarin[4] is a United States Army Special Operations unit which serves as an intelligence gathering special mission unit[5][6][7] of Joint Special Operations Command. Originally subordinated to the US Army Intelligence and Security Command (INSCOM), it is one of the least known intelligence components of the United States military,[2] tasked with collecting actionable intelligence during or prior to missions by other US special operations forces, particularly other tier one special mission units including 1st SFOD-D and DEVGRU.[2]
The unit is known by many names, USAISA was the official name of the unit from 1981 to 1989; previously it was known as the Field Operations Group (FOG), created in September 1980.
