Royal Marines

The Royal Marines (RM) are the marines and amphibious infantry of the British 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 and Arctic warfare.

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 highly manoeuvrable operational situations. As the British 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.

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. 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.
