Sheridan requested the support of the Royal Marine Mountain and Arctic Warfare Cadre, but was instead given 19 (Mountain) Troop from D Squadron Special Air Service (SAS) from Ascension Island. In the event, the whole of D Squadron comprising not only the Mountain Troop, but also 16 (Mobility) Troop, 18 (Air) Troop and 17 (Boat) Troop along with the Squadron HQ all joined the force at Ascension. Finally, 2 Troop, Special Boat Squadron (2 SBS) and, as requested by Sheridan, two Naval Gunfire Forward Observation Parties (NGFOs) also joined the task group.
