A long-range reconnaissance patrol, or LRRP, is a small, well-armed reconnaissance team that patrols deep into 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. Postwar, the role was carried in various North Atlantic Treaty Organization (NATO) and British Commonwealth countries by units that could trace their origins to these wartime creations such as the British SAS, Australia's Special Air Service Regiment and the New Zealand Special Air Service, 1er RPIMa, 13e RDP, GCP, Groupement de Commandos Mixtes Aéroportés in France and the United States Army Rangers, Long Range Surveillance teams, and the dismounted reconnaissance troops of RSTA squadrons.
History As indicated, the use of scouts is ancient, however, during the French and Indian War (1754–1763), the techniques of long-range reconnaissance and raiding were significantly implemented by the British in colonial North America. The British employed Major Robert Rogers to make long-range attacks against the French and their Indian allies along the frontiers of the British colonies and New France. The achievements of Major Roberts's dozen companies of approximately 1,200 men during the French and Indian War were so extraordinary that his doctrine, "Standing Orders, Rogers' Rangers," 1759, became the cornerstone of future U.S. Army long-range reconnaissance patrol units.
Long-range reconnaissance patrol by nation
Australia
During the Second World War, the 2/1st North Australia Observer Unit was tasked with patrolling the remote areas of northern Australia on horseback. Many from the Unit were recruited to join M Special Unit and Z Special Unit for long-range specialist reconnaissance and sabotage behind Japanese lines. From 1966 until 1971 troopers from the Australian Special Air Service Regiment (SASR) served in Vietnam as part of the 1st Australian Task Force at Nui Dat, Phuoc Tuy Province. Missions included medium range reconnaissance patrols, observation of enemy troop movements, and long range offensive operations and ambushing in enemy dominated territory in support of 1ATF operations throughout Phuoc Tuy Province as well as Bien Hoa, Long Khanh and Binh Tuy provinces. In the 1980s the Regional Force Surveillance Units (NORFORCE, The Pilbara Regiment and 51st Battalion, Far North Queensland Regiment) were formed to conduct long-range reconnaissance and surveillance patrols in the sparsely populated and remote regions of northern Australia.
Canada The Canadian Rangers conduct long-range surveillance or sovereignty patrols in the sparsely settled areas of Northern Canada. Although part of the Canadian Army, they are an irregular military force. Patrol Pathfinders units form part of the Reconnaissance Platoon of the 3rd (Light Infantry) Battalion of each Regular Force infantry Regiment. Patrol Pathfinders are trained in airborne and amphibious insertion, including by submarine, and conduct deep reconnaissance missions
Denmark The Danish Defence Forces had three Long-Range Surveillance companies (LRSC) known as "Patrol-Companies" (PTLCOY): two assigned to the two Land Commands: LANDJUT and LANDZEALAND (Corps-level) (abbreviated "SEP/ELK" and "SEP/VLK" for: "Specielle Efterretningspatruljer/Østre resp. Vestre Landskommando" i.e. Special Intelligence Patrols) – two all-volunteer units within the Danish Home Guard - that was changed into the Special Support and Reconnaissance Company (SSR) in 2007 as a Special Reconnaissance (SR) Company dedicated to supporting the Danish Special Operations. The third and last company (PTLCOY/DDIV) was assigned to the Jutland Division (later Danish Division/DDIV) and was trained by instructors from the Danish Army Special Operations Forces: Jægerkorpset (i.e. Hunter Force) in Aalborg. PTLCOY/DDIV was disbanded in 2002 due to budget-cuts and the intent to implement UAV in the Danish Army as the primary means of ISR. The first UAV project later failed and was disbanded too. In addition to these units, the 3rd Reconnaissance Battalion, Guard Hussar Regiment, also has Long range reconnaissance capabilities, particularly in 1st and 2nd Light Reconnaissance Squadrons (1.LOPESK & 2.LOPESK), whose primary role is long range reconnaissance and sabotage in light vehicles and with minimal support and resupply. Likely to be the world's smallest LRS unit is the Sirius Dog Sled Patrol (Danish: Slædepatruljen Sirius), known informally as Siriuspatruljen (the Sirius Patrol). It is a small squad-sized elite unit in the Danish Navy, that enforces Danish sovereignty in the Arctic wilderness of northern and eastern Greenland, and conducts long-range reconnaissance patrolling. Patrolling is usually done in pairs, sometimes for four months and often without additional human contact.
Finland
In Finland, long-range patrols (kaukopartio) were especially notable during World War II. For example, Erillinen Pataljoona 4 (4th Detached Battalion), a command of four different long-range patrol detachments; Detachment Paatsalo, Detachment Kuismanen, Detachment Vehniäinen and Detachment Marttina, operated in the Finnish-Soviet theater of WWII, also known as the Continuation War, from 1941 through 1944. These units penetrated Soviet lines and conducted reconnaissance and destroy missions. During the trench warfare period of the war, long-range patrols were often conducted by special Finnish Sissi troops. After the war, NATO hired former members of the 4th Detached Battalion to spy on Soviet Union's military bases in the Kola Peninsula and Karelian Isthmus. NATO ended the spy operation in 1957. From then on, espionage data was obtained from forward satellites. Former President of Finland, Mauno Koivisto, served in Lauri Törni's specially designed Jäger Company (called Detachment Törni) in the Finnish 1st Infantry Division. Lauri Törni became a US citizen and entered the US Army Special Forces. He gave important knowledge in long-range patrolling techniques and was declared MIA during the Vietnam War in 1965. His remains were later found, brought to the US, and buried in Arlington on 26 June 2003.
