The real Rat Patrol. Here's a British SAS and Long Range Desert Group (LRDG) unit returning from three month patrol 18 JAN 1943. The Rat Patrol TV series was based on the LRDG. In reality, the LRDG was under the command (and part of) the British Army and was originally manned by New Zealanders. Soon, it could boast Austrailan, Rhodesian, South African, British, etc., troops, also. Once the U.S.A. entered the war, the LRDG included some Americans. The original vehicles used were 2WD Chevrolet and heavy Ford 4WD trucks, with Jeeps joining in 1942 (first as command and staff vehicles) as the Chevys and heavy Fords tended to get stuck, even with the sand mats they carried and the flotation tires mounted on them.
