Special Branch is a label customarily used to identify units responsible for matters of national security in British and Commonwealth police forces, as well as in Ireland's Garda Síochána. A Special Branch unit acquires and develops intelligence, usually of a political nature, and conducts investigations to protect the State from perceived threats of subversion -- particularly, terrorism and other extremist activity.
