Made up of members of the Coldstream and Scots Guards, British Yeomanry cavalry regiments, New Zealanders, South Africans, and Indian Army men, the Long Range Desert Group was perhaps the most effective of all the "special forces" established by the Allies during the Second World War. It was able to go thousands of miles into enemy territory, well-armed and carrying its own supplies of petrol, food and even water to last for weeks at a time - something quite new in military history.
