Royal Marines Commandos

His Majesty's Royal Marines are the United Kingdom's special operations-capable naval infantry force and constitute one of the five fighting arms of the Royal Navy. They provide a company-sized sub-unit to the Special Forces Support Group, personnel for landing craft crews, and personnel for the Royal Navy's military bands.

The Corps traces its origins to the "Duke of York and Albany's Maritime Regiment of Foot", formed on 28 October 1664. The first Royal Marines commando unit was formed at Deal, Kent, on 14 February 1942 and was designated "The Royal Marine Commando".
