The vast majority of Claret tasks were undertaken by British infantry units, including all Gurkha battalions. Special forces operations were undertaken by the British Special Air Service, Special Boat Sections, Guards Independent Parachute Company, Gurkha Independent Parachute Company, patrol companies of the Parachute Regiment (C Company 2nd and D Company 3rd Battalions), the Australian Special Air Service Regiment and the 1 Ranger Squadron, New Zealand Special Air Service. The reconnaissance and intelligence gathering activities of the Border Scouts, mostly trained by 22 SAS, are unclear (apart from their accompanying many infantry patrols). The extent to which Malaysian Army units undertook Claret operations is also unclear.
