The Future Commando Force is designed to modernise the way Royal Marines operate.
It has been described by the Royal Navy as the most significant transformation and rebranding programme since the Second World War.
Personnel are continuing to test elements of the Future Commando Force – but what exactly does it involve?
The Ministry of Defence says it will offer the UK a force ready to deploy around the world immediately, on tasks such as warfighting, combat missions, and humanitarian duties.
This could also involve persistent forward deployments and special operations, including supporting UK Carrier Strike Groups and "refined" NATO contributions.
The Royal Marines recently established the Vanguard Strike Company, a new unit of more than 150 Marines and British Army Commandos, due to take shape by the end of 2020.
The Royal Navy said Vanguard Strike Company will "shape how the Royal Marines Commandos of the future will operate around the globe", and will have access to "game-changing technology and weaponry".
The service also said company personnel will work in "small, versatile teams" tailored for their mission, delivering "a more agile and lethal capability".
