They were created in the 1970s specifically to deal with the growing threat of terrorism.

    SAD

    The Special Activities Division (SAD) of the CIA are engaged in both clandestine political action and paramilitary special operations. What does that mean? That officially, they don’t exist. If they’re compromised during an overseas mission, the government will officially deny any knowledge.

    Also known as the United States Army Intelligence Support Activity (USAISA), these are the guys who go out and collect intel for many of the other top Special Ops groups in advance of missions. These guys are so secretive we don’t even know what their current name is.
