The Royal Navy (RN) is the naval warfare force of the United Kingdom, British Overseas Territories and Crown Dependencies, and a component of His Majesty's Naval Service. Although warships were used by English and Scottish kings from the early medieval period, the first major maritime engagements were fought in the Hundred Years' War against France. The modern Royal Navy traces its origins to the English Navy of the early 16th century; the oldest of the UK's armed services, it is consequently known as the Senior Service.
The Royal Marines, also known as the Royal Marines Commandos, and officially as the Corps of Royal Marines, are the United Kingdom's amphibious special operations capable commando force, one of the five fighting arms of the Royal Navy, and provide a company strength unit to the Special Forces Support Group (SFSG). The Royal Marines trace their origins back to the formation of the "Duke of York and Albany's maritime regiment of Foot" on 28 October 1664, and the first Royal Marines Commando unit was formed at Deal in Kent on 14 February 1942 and designated "The Royal Marine Commando".
Commander is a common naval officer rank as well as a job title in many armies. Commander is also used as a rank or title in other formal organizations, including several police forces. In several countries, this naval rank is termed as a frigate captain.
United Kingdom Commando Force (UKCF), previously called 3 Commando Brigade, is the UK's special operations-capable commando formation of the Royal Marines. It is composed of Royal Marine Commandos and commando qualified personnel from the Royal Navy, British Army and Royal Air Force.
The Commander-in-Chief Fleet (CINCFLEET) was the admiral responsible for the operations of the ships, submarines and aircraft of the British Royal Navy from 1971 until April 2012.

Colonel commandant is a military title used in the armed forces of some English-speaking countries. The title, not a substantive military rank, could denote a senior colonel with authority over fellow colonels. Today, the holder often has an honorary role outside the executive military structure, such as advocacy for the troops.

In the British Army, a major general is the customary rank for the appointment of division commander. In the Royal Marines, the Commandant General holds at least the rank of major general.
The Fleet Marine Force, Pacific (FMFPAC) is the largest maritime landing force in the world. Its units are spread across the Pacific Ocean and reports to the United States Pacific Command.

FMFPAC is under operational control of the Commander, United States Pacific Fleet (COMPACFLT), when deployed.
The Navy Command is the current headquarters body of the Royal Navy, and as of 2012 its major organisational grouping. It is a hybrid, neither a command, nor simply an installation. Royal Navy official writings describe Navy Command Headquarters both as a physical site, on Whale Island, Hampshire, a collective formed of the most senior RN officers, and as a budgetary grouping.
