The Future Commando Force (FCF) is an in-progress modernisation programme and transformation of the role and operations of the Royal Marines. The FCF essentially retasks 40 Commando and 45 Commando with forming two Littoral Response Groups (LRGs) which will be permanently deployed, though other units from 3 Commando Brigade are also included in the composition of LRGs, as well as changing the role and operations of the Royal Marines and the equipment and tactics they use. The FCF concept was created before 2019, when the first exercises and experiments with the FCF began. It was reinforced in the Defence in a Competitive Age command paper, which followed the Integrated Review. It describes the Royal Marines as a forward-deployed maritime special operations/special operations capable force which will work with greater agility and autonomy, and in smaller teams that specialise in raids within littoral zones, and operations within grey zones and other special operations to relieve and complement United Kingdom Special Forces (UKSF). The emphasis on the littoral role of the Royal Marines strongly links the FCF to the Littoral Strike concept, which is being developed and implemented by the LRGs. The FCF is also strongly linked to the "Autonomous Advanced Force" concept by its emphasis on leveraging new technologies to augment commandos on operations. A series of exercises from 2019–present have been key to developing the FCF, chiefly with experimentation.

40 Commando RM is a battalion-sized formation of the British Royal Marines and subordinate unit within 3 Commando Brigade, the principal Commando formation, under the Operational Command of Commander in Chief Fleet. Their barracks are at Norton Manor Camp, Norton Fitzwarren near Taunton in Somerset.
