The Ranger Special Operations Vehicle (RSOV) is a light military vehicle of the U.S. Army's 75th Ranger Regiment, based on the Land Rover Defender. The RSOV is not meant to be an assault vehicle, but rather a rapid defensive platform.

The Land Rover Defender is a series of British off-road cars and pickup trucks. They consistently have four-wheel drive, and were developed in the 1980s from the original Land Rover series which was launched at the Amsterdam Motor Show in April 1948. Following the 1989 introduction of the Land Rover Discovery, the term 'Land Rover' became the name of a broader marque, and thus no longer worked as the name of a specific model; thus in 1990 Land Rover renamed the 90 and 110 as Defender 90 and Defender 110 respectively. The 127 became the Defender 130.
