[7][8] The Royal Marines and the Ranger Regiment are special operations–capable forces, but they do not form part of UKSF.

[9][10] The government and Ministry of Defence (MOD) have a policy of not commenting on the UKSF, in contrast to other countries including the United States, Canada, and Australia.

[17][18][19] Their role as part of 1 ISR Bde was to conduct Human, Environment, Reconnaissance, and Analysis (HERA) patrols.

[31] The Chief of the Defence Staff has said that the Ranger Regiment will be similar to the United States Army Special Forces, known as the "Green Berets".

[36][37] The Marines will often be permanently deployed in two new Littoral Response Groups, with one in Northern Europe and the other in the Indian Ocean.
