Supreme Allied Commander in the context of "Supreme Allied Commander Atlantic"

Louis Francis Albert Victor Nicholas Mountbatten, 1st Earl Mountbatten of Burma (born Prince Louis of Battenberg; 25 June 1900 – 27 August 1979), commonly known as Lord Mountbatten, was a British statesman, Royal Navy officer and close relative of the British royal family. He was born in the United Kingdom to the prominent Battenberg family. He was a maternal uncle of Prince Philip, Duke of Edinburgh, and a second cousin of King George VI. He joined the Royal Navy during the First World War and was appointed Supreme Allied Commander, South East Asia Command, in the Second World War. He later served as the last Viceroy of India and briefly as the first Governor-General of the Dominion of India.

Mountbatten attended the Royal Naval College, Osborne, before entering the Royal Navy in 1916. He saw action during the closing phase of the First World War, and after the war briefly attended Christ's College, Cambridge. During the interwar period, Mountbatten continued to pursue his naval career, specialising in naval communications. Following the outbreak of the Second World War, he commanded the destroyer HMS Kelly and the 5th Destroyer Flotilla. He saw considerable action in Norway, in the English Channel, and in the Mediterranean. In August 1941, he received command of the aircraft carrier HMS Illustrious.

Ferdinand Foch (/fɒʃ/ FOSH, French: [fɛʁdinɑ̃ fɔʃ]; 2 October 1851 – 20 March 1929) was a French general, Marshal of France and a member of the Académie Française and Académie des Sciences. He distinguished himself as Supreme Allied Commander on the Western Front during the First World War in 1918.

A commander during the First Marne, Flanders and Artois campaigns of 1914–1916, Foch became Supreme Allied Commander in late March 1918 in the face of the all-out German spring offensive. He successfully coordinated the French, British and American efforts, deftly handling his strategic reserves. He stopped the German offensive and launched a war-winning counterattack. In November 1918, Marshal Foch accepted the German cessation of hostilities and was present at the Armistice of 11 November 1918.

China Burma India Theater (CBI) was the United States military designation during World War II for the China and Southeast Asian or India–Burma (IBT) theaters. Operational command of Allied forces (including U.S. forces) in the CBI was officially the responsibility of the Supreme Commanders for South East Asia or China. In practice, U.S. forces were usually overseen by General Joseph Stilwell, the Deputy Allied Commander in China; the term "CBI" was significant in logistical, material, and personnel matters; it was and is commonly used within the US for these theaters.

U.S. and Chinese fighting forces in the CBI included the Chinese Expeditionary Force, the Flying Tigers, transport and bomber units flying the Hump, including the Tenth Air Force, the 1st Air Commando Group, the engineers who built the Ledo Road, the 5307th Composite Unit (Provisional), popularly known as "Merrill's Marauders", and the 5332d Brigade, Provisional or 'Mars Task Force', which assumed the Marauders' mission.
