UNSC Army Special Operations Group

The Counterterrorism Activity Warfare Section (CAWS), commonly known as "Counterterrorism Activity", is a field special operations detachment jointly operated by the UNSC Office of Naval Intelligence and the UNSC Special Operations Command.

It had its genesis as a special-access program by ONI known as "JUST CAUSE" that was funded and authorized to train and organize advanced special operations forces, presumably for the role of counterterrorism and to increase UNSC civilian security. Although JUST CAUSE's results were undisclosed, it was later authorized by the Director of Special Intelligence to full operational autonomy, and JUST CAUSE was promoted from a black project to a recognized military unit under ONI's and UNSCSOCOM's jurisdiction.

Little information is known about CAWS, and its size and composition remain undisclosed, with the Office of Naval Intelligence paying a particular interest in protecting the privacy of CAWS's operations. CAWS is known to be one of the extremely few field units granted complete operational jurisdiction and unrestricted area of operations (AOR), making it unique in its striking potential and liberty. Delta Team was a tactical unit attached to CAWS.
