Roger James Allen Courtney MC, known as Jumbo, established the Special Boat Sections which saw action in World War II. These would eventually lead to the formation of the UK Special Boat Service.

Roger James Allen Courtney (1902 -1949) was a bank clerk in Leeds, England, before he became a professional white hunter and gold prospector in East Africa. He was also a sergeant in the Palestinian Police Force.

When World War II began, he travelled from Africa (where he was big-game hunting) to England to join the Army as a "commando folding kayaker". When his ideas were rebuffed, he joined the King's Royal Rifle Corps as a Rifleman. Soon promoted to Corporal, he was commissioned in November 1939.

Courtney became an Army Commando recruit in mid-1940, and was sent to the Combined Training Center in Scotland. He was unsuccessful in his initial attempts to convince Admiral of the Fleet Roger Keyes and later Admiral Theodore Hallett, commander of the Combined Training Center, that his idea of a folding kayak brigade would be effective. He decided to infiltrate the HMS Glengyle, a Landing Ship, Infantry anchored in the River Clyde. Courtney paddled to the ship, climbed aboard undetected, wrote his initials on the door to the captain's cabin, and stole a deck gun cover. He presented the soaking cover to a group of high-ranking Royal Navy officers meeting at a nearby Inveraray hotel. He was promoted to Captain, and given command of twelve men, the first Special Boat Section.

Courtney's brother Gruff later commanded a second section of the SBS. The units carried out several raids during the early years of the war, especially in the Mediterranean, which validated Courtney's idea of mounting small-scale attacks from the sea. But heavy losses led to its personnel being amalgamated in 1943 into the new Special Boat Squadron, led by George Jellicoe. Roger Courtney lost his command, became a colonial administrator and died in Somaliland aged 46.

George Patrick John Rushworth Jellicoe, 2nd Earl Jellicoe, KBE, DSO, MC, PC, FRS, FRGS (4 April 1918 – 22 February 2007) was a British politician, diplomat and businessman.

In 1943, he was named Commander of the Special Boat Regiment Middle East and he was promoted to the rank of lieutenant-colonel. He was eventually promoted to brigadier. For the remainder of the war, his SBS command conducted secretive and dangerous operations along the coasts of Italy and Yugoslavia. In 1944, he won the MC for one of these actions. At the end of the war, Jellicoe was among the first Allied soldiers to enter German-occupied Athens, beating the communist-controlled guerrillas ELAS, to create a pro-Allied presence in the capital.

Years later, when First Lord of the Admiralty, Jellicoe told at least one reporter, "The only serious military distinction I ever achieved was having a new type of assault boat named after me. It was called I am ashamed to say, the Jellicoe Inflatable Intruder Mark One."

Lord Jellicoe was the only son but sixth and youngest child of *John Jellicoe, 1st Earl Jellicoe, who was a First World War naval commander, commander at the Battle of Jutland, and Admiral of the Fleet, and his wife Florence Gwendoline (died 1964), who was the second daughter of Sir Charles Cayzer, 1st Bt., of Gartmore, Perthshire. George Jellicoe was one of the longest-serving parliamentarians in the world, being a member of the House of Lords for 68 years (1939–2007).
