It is usually abbreviated to "Adm" or "ADM". - A flag officer is a commissioned officer in a nation's armed forces senior enough to be entitled to fly a flag to mark the position from which the officer exercises command. - Vice admiral is a senior naval flag officer rank, equivalent to lieutenant general and air marshal. A vice admiral is typically senior to a rear admiral and junior to an admiral.

Lying off the north-western coast of the European mainland, it includes the island of Great Britain (the name of which is also loosely applied to the whole country), the north-eastern part of the island of Ireland, and many smaller islands. Northern Ireland is the only part of the UK that shares a land border with another sovereign statethe Republic of Ireland. Apart from this land border, the UK is surrounded by the Atlantic Ocean, with the North Sea to its east, the English Channel to its south and the Celtic Sea to its south-south-west, giving it the 12th-longest coastline in the world. The Irish Sea lies between Great Britain and Ireland. With an area of , the UK is the 78th-largest sovereign state in the world and the 11th-largest in Europe. It is also the 21st-most populous country, with an estimated 65.1 million inhabitants. Together, this makes it the fourth most densely populated country in the European Union. - Schout - bij - nacht ( pronounced ( sxud bi nxt ) ) is a Dutch Naval rank , equivalent to rear admiral in the US Navy and Royal Navy . It is the second most junior admiral position of the Dutch Navy , ranking above commandeur ( '' commodore '' ) and below a vice-admiraal ( '' vice admiral '' ) . The rank of schout - bij - nacht originated between the 15th and 16th century . Interpreted as '' watch - at - night '' , the schout - bij - nacht was the officer who supervised the ship when the captain was asleep .

Although warships were used by the English kings from the early medieval period, the first major maritime engagements were fought in the Hundred Years War against the kingdom of France. The modern Royal Navy traces its origins to the early 16th century; the oldest of the UK's armed services, it is known as the Senior Service. - Air marshal (Air Mshl or AM) is a three-star air-officer rank which originated in and continues to be used by the Royal Air Force. The rank is also used by the air forces of many countries which have historical British influence and it is sometimes used as the English translation of an equivalent rank in countries which have a non-English air force-specific rank structure. Air marshal is a three-star rank and has a NATO ranking code of OF-8, equivalent to a vice-admiral in the Royal Navy or a lieutenant-general in the British Army or the Royal Marines.

The term is also used by some armed forces which are not NATO members. Typically, three-star officers hold the rank of vice admiral, lieutenant general, or in the case of those air forces with a separate rank structure, air marshal. - Rear admiral is a naval commissioned officer rank above that of a commodore and captain, and below that of a vice admiral. It is generally regarded as the lowest of the "admiral" ranks, which are also sometimes referred to as "flag officers" or "flag ranks".

The rank traces its origins to the Middle Ages, where the title of lieutenant general was held by the second in command on the battlefield, who was normally subordinate to a captain general. - The French Navy ("national navy"), informally , is the maritime arm of the French Armed Forces. Tracing its roots back to 1624 it is one of the world's oldest naval forces and historically played a key part in establishing the French colonial empire. Since the early foundings, its roles have been defined as maintaining intelligence, protecting populations, preventing crises, intervening wherever necessary to reestablish peace, and dissuading any threats against vital French interests. The Marine nationale consists of four branches: the "Force d'Action Navale", the "Forces Sous-marines", the "Aeronavale" and the "Fusiliers Marins" (including Commandos Marine). As a blue-water navy the Marine nationale operates a wide range of fighting vessels, including a nuclear-powered aircraft carrier, nuclear-powered submarines, frigates, patrol boats and support ships. The French Navy does not use prefixes of the names of its ships (such as the Royal Navy uses HMS, for instance). Foreign commentators sometimes use the prefixes "FS" (for "French Ship") or FNS (for "French Navy Ship"); these are not official, however. - A four-star rank is the rank of any four-star officer described by the NATO OF-9 code. Four-star officers are often the most senior commanders in the armed services, having ranks such as (full) admiral, (full) general, or air chief marshal.
