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

Context paragraphs:
Two-star rank: An officer of two-star rank is a senior commander in many of the armed services holding a rank described by the NATO code of OF-7.  The term is also used by some armed forces which are not NATO members.  Typically, two-star officers hold the rank of rear admiral, counter admiral, major general, or in the case of those air forces with a separate rank structure, air vice-marshal.

Stabsarzt: Stabsarzt (short: StArzt or SA), literally meaning "staff physician," is a military commissioned officer rank in German speaking armed forces.  In the German Bundeswehr and the former Wehrmacht and Reichswehr, it describes a qualified or licensed surgeon or dentist who practises military medicine, with a rank equal to captain (German: Hauptmann) in the army or air force or lieutenant (German: Kapitänleutnant) in the navy.  This rank corresponds to NATO code OF2, and is known in English as captain (Dr.) for army or air force officers or lieutenant (Dr.) for naval officers.  The rank was historically also used in the Austro-Hungarian Common Army and corresponded to major or the NATO code OF-3, known as major (Dr.) in English.

Vice admiral: 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.  In many navies, vice admiral is a three-star rank with a NATO code of OF-8, although in some navies like the French Navy it is an OF-7 rank, the OF-8 code corresponding to the four-star rank of squadron vice-admiral.

One-star rank: An officer of one-star rank is a senior commander in many of the armed services holding a rank described by the NATO code of OF-6.  The term is also used by some armed forces which are not NATO members.  Typically, one-star officers hold the rank of commodore, flotilla admiral, brigadier general, brigadier, or in the case of those air forces with a separate rank structure, air commodore.

Henry Scudamore, 3rd Duke of Beaufort: Henry Somerset-Scudamore, 3rd Duke of Beaufort (23 March 1707 – 26 February 1745) born Henry Somerset, was an English nobleman and peer.  He was the elder son of Henry Somerset, 2nd Duke of Beaufort and his second wife, Rachel Noel.  As his father's eldest son and heir to his father's title he was known as (styled) Marquess of Worcester, a courtesy title.  On his father's death on 24 April 1714 he succeeded him and became 3rd Duke of Beaufort.

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.

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.

Lady Henry Somerset Memorial: The Lady Henry Somerset Memorial, also known as the Lady Henry Somerset's Children's Fountain, is a Grade II-listed memorial to Lady Henry Somerset, located in the Victoria Embankment Gardens in Westminster, London.  It was listed on 24 February 1958.

Three-star rank: An officer of three-star rank is a senior commander in many of the armed services holding a rank described by the NATO code of OF-8.  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.

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.
