The Royal Marines Commandos might soon be joining the ranks of the United Kingdom’s Special Forces (UKSF).

Although an elite unit as it is, the Commandos are currently considered a step down from Britain’s SOF. They are the country’s premier light infantry amphibious unit. In recent years, they were deployed in both Iraq and Afghanistan, and they are also the go-to option for large-scale Arctic warfare contingencies.

UKSF is comprised of the legendary Special Air Service (SAS), the Special Boat Service (SBS) – an equivalent of SEAL Team 6 – the Special Reconnaissance Regiment (SRR), and the Special Forces Support Group (SFSG), which contains Royal Marines who have successfully passed the SFSG selection and assessment process.

Under the Special Purpose Task Group (SPTG) concept, which is set to be operational by 2021, the Royal Marines Commandos might see their capabilities increase and the unit becoming a Special Operations force. The Future Command Force (FCF) initiative, which plans Britain’s defence capabilities for the next years, envisions the 3 Commando Brigade as a flexible force that can operate on a no-notice basis from littoral strike ships that would act as floating SOF bases.
