The 1st Special Service Force was an elite American–Canadian commando unit in World War II, under the command of the United States Fifth Army. The unit was organized in 1942 and trained at Fort William Henry Harrison near Helena, Montana, in the United States. The Force served in the Aleutian Islands, and fought in Italy, and southern France before being disbanded in December 1944.
The modern American and Canadian special operations forces trace their heritage to this unit. In 2013, the United States Congress passed a bill to award the 1st Special Service Force the Congressional Gold Medal.
Geoffrey Pyke was an English journalist, educationalist, and later an inventor whose clever, but unorthodox, ideas could be difficult to implement. In lifestyle and appearance, he fit the common stereotype of a scientist-engineer-inventor or in British slang, a "boffin". This was part of the British approach in World War II, of encouraging innovative warfare methods and weapons, that was personally backed by Churchill. Hobart's Funnies are another example.
While working for the British Combined Operations Command, Pyke devised a plan for the creation of a small, elite force capable of fighting behind enemy lines in winter conditions. This was to have been a commando unit that could be landed, by sea or air, into occupied Norway, Romania and/or the Italian Alps on sabotage missions against hydroelectric plants and oil fields.
In Norway, the chief industrial threat was the creation of the heavy water used in the German atomic weapon research at Rjukan. Furthermore, attacks on Norwegian power stations, which supplied the country with 49% of its power, might drive the Axis powers out of the country and give the Allies a direct link to Russia. In Romania, there were the strategically important Ploiești oil fields that met one quarter of the Germans' consumption, and Italian hydroelectric plants powered most of south German industry. Pyke requested that a tracked vehicle be developed especially for the unit, capable of carrying men and their equipment at high speed across snow-covered terrain.
