The Royal Marines (RM) are the marine corps and amphibious infantry of the United Kingdom's armed forces and, along with the Royal Navy and Royal Fleet Auxiliary, form the Naval Service. They are also the United Kingdom's specialists in mountain warfare and Arctic warfare. A core component of the country's Rapid Deployment Force, the Corps' 3 Commando Brigade is capable of operating independently and is highly trained as a commando force. It can deploy quickly and fight in any terrain in the world.

The Royal Marines are a maritime-focused, amphibious, light infantry force capable of deploying at short notice in support of the United Kingdom Government's military and diplomatic objectives overseas and are optimised for operational situations requiring highly manoeuvreable forces. As the United Kingdom Armed Forces' specialists in cold weather warfare the Corps provide lead element expertise in the NATO Northern Flank and are optimised for high altitude operations.

In common with the other armed forces, the Royal Marines can provide resources for Military Aid to the Civil Community and Military Aid to the Civil Power operations and have done so.


The main operational capability of the Corps comprises a number of Battalion-sized units, of which three are designated as "Commandos". These are integrated into 3 Commando Brigade (with a number of British Army units). The Royal Marines also have a number of independent units including the Special Boat Service.

Rank InsigniaEdit


Royal Marine officer ranks used to rise as high as General, however with the reduction in the size of the Royal Marines, the rank of the Commandant of the Royal Marines has been reduced to Major General. As the Royal Marines are part Royal Navy, the military head of the Marines is in fact the First Sea Lord.
