A long-range reconnaissance patrol, or LRRP (pronounced "lurp"), is a small, well-armed reconnaissance team that patrols deep in enemy-held territory. The concept of scouts dates back to the origins of warfare itself. However, in modern times these specialized units evolved from examples such as Rogers' Rangers in colonial British America, the Lovat Scouts in World War One, the Long Range Desert Group and the Special Air Service in the Western Desert Campaign and North West Europe, similar units such as Force 136 in East Asia, and the special Finnish light infantry units during the Second World War.
