Nations around the world particularly wanted a counter-terrorism capability like the SAS. The Ministry of Defence and Foreign and Commonwealth Office often loan out training teams from the Regiment, particularly to the Gulf States to train bodyguard teams now focused on CT. The Regiment has also had a long-standing association with the US Army's Delta Force, with the two units often having swapped techniques and tactics, as well as conducting joint training exercises in North America and Europe. Other nations' CT units developed close ties with the Regiment, including the Australian SAS, New Zealand SAS, GSG 9 and GIGN.
