Question: What is the NATO code of FitzRoy James Henry Somerset's rank?

full_context: Document 1: Admiral flote: Admiral flote (lit. Admiral of the Fleet) is the fifth and highest Admiral of the Croatian Navy. This officer is referred to as, and is considered the equivalent of, a five-star Fleet Admiral. The insignia for a Croatian Senior Admiral is two thick rank stripes on both the sleeve and shoulder board. Between 1995 and 2002, the rank was called Stožerni admiral, meaning "Staff Admiral", analogous to "Stožerni general" for the ground forces.
Document 2: Baron Raglan: Baron Raglan, of Raglan in the County of Monmouth, is a title in the Peerage of the United Kingdom. It was created in 1852 for the military commander Lord FitzRoy Somerset, chiefly remembered as commander of the British troops during the Crimean War. Somerset was the youngest son of Henry Somerset, 5th Duke of Beaufort (see Duke of Beaufort for earlier history of the family). His second but eldest surviving son, the second Baron, served as a Lord-in-Waiting (government whip in the House of Lords) from 1866 to 1868 in the Conservative administrations of the Earl of Derby and Benjamin Disraeli. He was succeeded by his son, the third Baron. He held office as Under-Secretary of State for War between 1900 and 1902 in the Conservative government of Lord Salisbury. His eldest son, the fourth Baron, was a soldier and also served as Lord Lieutenant of Monmouthshire. The fifth Baron was active in the House of Lords but lost his seat in the upper chamber of parliament after the passing of the House of Lords Act 1999. s of 2012 the title is held by the fourth Baron's third but second surviving son, the sixth Baron, who succeeded in 2010. As a descendant of the fifth Duke of Beaufort, Lord Raglan is also in remainder to this peerage and its subsidiary titles.
Document 3: Colin Campbell, 1st Baron Clyde: Field Marshal Colin Campbell, 1st Baron Clyde, (20 October 1792– 14 August 1863), was a British Army officer. After serving in the Peninsular War and the War of 1812, he commanded the 98th Regiment of Foot during the First Opium War and then commanded a brigade during the Second Anglo-Sikh War. He went on to command the Highland Brigade at the Battle of Alma and with his "thin red line of Highlanders" he repulsed the Russian attack on Balaclava during the Crimean War. At an early stage of the Indian Mutiny, he became Commander-in-Chief, India and, in that role, he relieved and then evacuated Lucknow and, after attacking and decisively defeating Tatya Tope at the Second Battle of Cawnpore, captured Lucknow again. Whilst still commander-in-chief he dealt with the 'White Mutiny' among East India Company troops, and organised the army sent east in the Second Opium War.
Document 4: Robert Ballard Long: Lieutenant-General Robert Ballard Long (4 April 1771 – 2 March 1825) was an officer of the British and Hanoverian Armies who despite extensive service during the French Revolutionary and Napoleonic Wars never managed to achieve high command due to his abrasive manner with his superiors and his alleged tactical ineptitude. Although he remained a cavalry commander in the Peninsular War between 1811 and 1813, the British commander Wellington became disillusioned with Long's abilities. Wellington's opinion was never expressed directly, though when the Prince Regent manoeuvred his favourite, Colquhoun Grant into replacing Long as a cavalry brigade commander, Wellington conspicuously made no effort to retain Long. Other senior officers, including Sir William Beresford and the Duke of Cumberland, expressed their dissatisfaction with Long's abilities. The celebrated historian, and Peninsula veteran, Sir William Napier was a severe critic of Beresford's record as army commander during the Albuera Campaign; in criticising Beresford he involved Long's opinions as part of his argument. The publication of Napier's history led to a long running and acrimonious argument in print between Beresford and his partisans on one side, with Napier and Long's nephew Charles Edward Long (Long having died before the controversy reached the public arena) on the other. Recently Long's performance as a cavalry general has received more favourable comment in Ian Fletcher's revisionist account of the British cavalry in the Napoleonic period.
Document 5: FitzRoy Somerset, 1st Baron Raglan: Field Marshal FitzRoy James Henry Somerset, 1st Baron Raglan, {'1': ", '2': ", '3': ", '4': "} (30 September 1788 – 28 June 1855), known before 1852 as Lord FitzRoy Somerset, was a British Army officer. As a junior officer he served in the Peninsular War and the Hundred Days, latterly as military secretary to the Duke of Wellington. He also took part in politics as Tory Member of Parliament for Truro before becoming Master-General of the Ordnance. He became commander of the British troops sent to the Crimea in 1854: while his primary objective was to defend Constantinople he was ordered to besiege the Russian Port of Sevastopol. After an early success at the Battle of Alma, a failure to deliver orders with sufficient clarity caused the fateful Charge of the Light Brigade at the Battle of Balaclava. Despite further success at the Battle of Inkerman, a piecemeal allied assault on Sevastopol in June 1855 was a complete failure. Raglan died later that month from a mixture of dysentery and clinical depression.
Document 6: Field marshal (India): Field marshal (or field marshal, abbreviated as FM) ( , ) is a five–star general officer rank and the highest attainable rank in the Indian Army. Field marshal is ranked immediately above general, but not exercised in the regular army structure. It is a largely ceremonial or wartime rank, having been awarded only twice. A field marshal's insignia consists of the national emblem over a crossed baton and sabre in a lotus blossom wreath.
Document 7: J. E. B. Seely, 1st Baron Mottistone: Major General John Edward Bernard Seely, 1st Baron Mottistone (31 May 1868 – 7 November 1947) was a British Army general and politician. He was a Conservative Member of Parliament (MP) from 1900 to 1904 and a Liberal MP from 1904 to 1922 and from 1923 to 1924. He was Secretary of State for War for the two years prior to the First World War, before being forced to resign as a result of the Curragh Incident. As General Jack Seely, he led one of the last great cavalry charges in history at the Battle of Moreuil Wood on his war horse Warrior in March 1918. Seely was a great friend of Winston Churchill and the only former cabinet minister to go to the front in 1914 and still be there four years later.
Document 8: Lord John Hay (Royal Navy officer, born 1827): Admiral of the Fleet Lord John Hay, GCB (23 August 1827 – 4 May 1916) was a Royal Navy officer and politician. After seeing action in 1842 during the First Opium War, he went ashore with the Naval Brigade and took part in the defence of Eupatoria in November 1854 and the Siege of Sevastopol in Spring 1855 during the Crimean War. He also took part in the Battle of Taku Forts in August 1860 during the Second Opium War. As a politician, he became Member of Parliament for Wick and later for Ripon. He was sent to the Mediterranean in July 1878 to take control of Cyprus and to occupy it in accordance with decisions reached at the Congress of Berlin. In a highly political appointment, he was made First Naval Lord in March 1886 when the Marquis of Ripon became First Lord of the Admiralty but had to stand down just five months later when William Gladstone's Liberal Government fell from power in August 1886.
Document 9: Field marshal (United Kingdom): Field Marshal has been the highest rank in the British Army since 1736. A five-star rank with NATO code OF-10, it is equivalent to an Admiral of the Fleet in the Royal Navy or a Marshal of the Royal Air Force in the Royal Air Force (RAF). A Field Marshal's insignia consists of two crossed batons surrounded by yellow leaves below St Edward's Crown. Like Marshals of the RAF and Admirals of the Fleet, Field Marshals traditionally remain officers for life, though on half-pay when not in an appointment. The rank has been used sporadically throughout its history and was vacant during parts of the 18th and 19th centuries (when all former holders of the rank were deceased). After the Second World War, it became standard practice to appoint the Chief of the Imperial General Staff (later renamed Chief of the General Staff) to the rank on his last day in the post. Army officers occupying the post of Chief of the Defence Staff, the professional head of all the British Armed Forces, were usually promoted to the rank upon their appointment.
Document 10: Fleet admiral (United States): Fleet admiral (abbreviated FADM), officially known as "Fleet Admiral of the United States Navy", is a five-star flag officer rank in the United States Navy. Fleet admiral ranks immediately above admiral and is equivalent to General of the Army and General of the Air Force. Although it is a current and authorized rank, no U.S. Navy officer presently holds it, with the last living U.S. Navy fleet admiral being Chester W. Nimitz, who died in 1966.
Document 11: List of Royal Air Force air chief marshals: The following is a list of Royal Air Force air chief marshals. The rank of air chief marshal is a four-star officer rank and currently the highest rank to which RAF officers may be promoted to in a professional capacity. Throughout the history of the RAF there have been 140 RAF officers promoted to air chief marshal and at present two RAF officers hold the rank in an active capacity, namely the Chief of the Air Staff (the only dedicated RAF 4-star post) and the Chief of the Defence Staff (the only tri-service 4-star post currently occupied by an air chief marshal).
Document 12: Gensui (Imperial Japanese Navy): Marshal-admiral (元帥海軍大将 , gensui-kaigun-taishō ) was the highest rank in the prewar Imperial Japanese Navy. The term "gensui" was used for both the navy and the Imperial Japanese Army, and was a largely honorific title awarded for extremely meritorious service to the Emperor. In the Meiji period, the title was awarded to five generals and three admirals. In the Taishō period it was awarded to six generals and six admirals, and in the Shōwa period it was awarded to six generals and four admirals. Equivalent to a five-star rank (OF-10), it is similar to Admiral of the Fleet in the UK Royal Navy and fleet admiral in the United States Navy.
Document 13: Admiral of the fleet: An admiral of the fleet or fleet admiral (sometimes also known as admiral of the navy or grand admiral) is a military naval officer of the highest rank. In many nations the rank is reserved for wartime or ceremonial appointments. It is usually a rank above admiral (which is now usually the highest rank in peace-time for officers in active service), and is often held by the most senior admiral of an entire naval service.
Document 14: Marshal of the Royal Air Force: Marshal of the Royal Air Force (MRAF) is the highest rank in the British Royal Air Force (RAF). In peacetime it was granted to RAF officers in the appointment of Chief of the Defence Staff (CDS), and to retired Chiefs of the Air Staff (CAS), who were promoted to it on their last day of service. While surviving marshals of the RAF retain the rank for life, the highest rank to which officers on active service are promoted is now air chief marshal. Although general promotions to Marshal of the Royal Air Force have been discontinued since the British defence cuts of the 1990s, further promotions to the rank may still be made in wartime, for members of the Royal Family and certain very senior RAF air officers in peacetime at the discretion of the monarch; all such promotions in peacetime are only honorary, however. In 2012, Charles, Prince of Wales was promoted to the rank while in 2014 Lord Stirrup, who had served as Chief of the Air Staff and Chief of the Defence Staff for over seven years, was also promoted.
Document 15: Lintorn Simmons: Field Marshal Sir John Lintorn Arabin Simmons (12 February 1821 – 14 February 1903) was a British Army officer. Early in his career he served as Inspector of Railways, Secretary of the Railways Commission and then Secretary of the Railway Department under the Board of Trade. He went on to be British Commissioner with the Turkish Army providing advice to General Omar Pasha during the Crimean War. He assisted the Turks at the defence of Silistra and then led them at the Battle of Giurgevo before landing with them at the Battle of Eupatoria and remaining with them for the Siege of Sevastopol. After that he became British Consul in Warsaw, Commander, Royal Engineers at Aldershot and then Director of the Royal Engineer Establishment in Chatham. He went on to be Lieutenant-Governor of the Royal Military Academy and subsequently Governor of the Academy. His last appointments were as Colonel Commandant of the Royal Engineers, as Inspector General of Fortifications and then as Governor of Malta.
