Question: Who is the founder of the British Army Unit which undertakes a number of roles including covert reconnaissance, counter-terrorism, direct action and hostage rescue?
Context: This is a list of notable current and former members of the United States Navy SEALs and Underwater Demolition Teams.  Founded in 1962, the SEALs are the U.S. Navy's principal special operations force.  The name "SEALs" represents the environments in which they operate: sea, air and land.  Navy SEALs are trained and have been deployed in a wide variety of missions, including direct action, special reconnaissance, unconventional warfare, foreign internal defense, hostage rescue, counter-terrorism, and other missions. Martin Dillon (born 1949) is an author and journalist from Belfast, Northern Ireland.  He worked for eighteen years at the BBC and has written plays and novels, but is best known for his non-fiction books about "the Troubles".  He has written books about the loyalist paramilitary Michael Stone and Special Air Service founder Paddy Mayne. The Comando Especial Anti-Terrorista ("Special Counter-Terrorism Command", CEAT) is a special operations unit and Executive Branch Security of El Salvador, created in 1985 during the El Salvadoran civil war and trained by United States Special Operations Forces.  Its main duties are counter-terrorism, hostage rescue and VIP protection.  Although under the direct command of the army chief of staff, the CEAT reportedly consisted of PH (Policia de Hacienda) members.  Anecdotal evidence has it that they are trained to ambush up to five hundred enemy combatants with only two commandos employing M18 Claymore anti-personnel land mines facing the killing zone of the planned ambush route and triggered by remote control. Hostage Rescue Force (Arabic: قوة إنقاذ الرهائن ) is Egypt's premier domestic counter-terrorism and hostage rescue unit.  It is subordinate to the National Security Directorate of the Egyptian Ministry of Interior. MARCOS, previously named as Marine Commando Force (MCF), is the special forces unit of the Indian Navy created for conducting special operations such as Amphibious warfare, Close Quarter Combat Counter-terrorism, Direct action, Special reconnaissance, Unconventional warfare, Hostage rescue, Personnel recovery, Combat search and rescue, Asymmetric warfare, Foreign internal defence, Counterproliferation, Amphibious reconnaissance including Hydrographic reconnaissance.  The MCF is specially organised, trained and equipped for the conduct of special operations in a maritime environment.  "MARCOS" is short for "Marine Commandos".  The force has gradually acquired experience and a reputation for professionalism over the three decades it has been in existence.  The MARCOS are capable of undertaking operations in all types of terrain, but are specialised in maritime operations in Jammu and Kashmir through the Jhelum River and Wular Lake, a 65 square kilometre freshwater lake.  Some MARCOS personnel are also attached with the Army special forces units conducting counter-terrorism operations in the area.  MARCOS are widely feared among the terrorists, who call them "Dadiwala fauj", meaning the "Bearded army" because of their bearded disguise in civil areas. General Staff Reconnaissance Unit 269, more commonly known as Sayeret Matkal (Hebrew: סיירת מטכ"ל‎ , General Staff Reconnaissance Unit) is a special forces unit of the Israel Defense Forces (IDF).  First and foremost a field intelligence-gathering unit, conducting deep reconnaissance behind enemy lines to obtain strategic intelligence, Sayeret Matkal is also tasked with counter-terrorism and hostage rescue beyond Israel's borders.  The unit is modeled after the British Army's Special Air Service, taking the unit's motto "Who Dares, Wins".  The unit is the Israeli equivalent of Delta Force of the United States and to the UK's Special Air Service.  It is directly subordinate to the IDF's Directorate of Military Intelligence. The 1st Special Forces Operational Detachment-Delta (1st SFOD-D), commonly referred to as Delta Force, Combat Applications Group (CAG), "The Unit", Army Compartmented Element (ACE), or within JSOC as Task Force Green, is an elite special mission unit of the United States Army, under operational control of the Joint Special Operations Command.  The unit is tasked with specialized missions primarily involving hostage rescue and counterterrorism, as well as direct action and special reconnaissance against high-value targets. Delta Force and its maritime counterpart, the U.S. Navy's SEAL Team Six (also known as "DEVGRU"), are the U.S. military's primary counterterrorism units.  Delta Force and DEVGRU perform the most highly complex, classified, and dangerous missions in the U.S. military, as directed by the U.S. National Command Authority. Para (Special Forces) is a special forces unit of the Indian Army's Parachute Regiment tasked with missions such as special operations, direct action, hostage rescue, counter-terrorism, unconventional warfare, special reconnaissance, foreign internal defense, counter-proliferation, counter-insurgency, seek and destroy and personnel recovery.  The unit's heritage stems from World War II, with the creation of the 50th Parachute Brigade in October 1941. The Special Air Service (SAS) is a special forces unit of the British Army.  The SAS was founded in 1941 as a regiment, and later reconstituted as a corps in 1950.  The unit undertakes a number of roles including covert reconnaissance, counter-terrorism, direct action and hostage rescue. The United States Army Special Forces; colloquially known as the Green Berets (due to their distinctive service headgear), are a special operations force tasked with five primary missions: unconventional warfare (the original and most important mission of Special Forces), foreign internal defense, special reconnaissance, direct action, and counter-terrorism.  The first two emphasize language, cultural, and training skills in working with foreign troops.  Other duties include combat search and rescue (CSAR), counter-narcotics, counter-proliferation, hostage rescue, humanitarian assistance, humanitarian demining, information operations, peacekeeping, psychological operations, security assistance, and manhunts; other components of the United States Special Operations Command (USSOCOM) or other U.S. government activities may also specialize in these secondary areas.  Many of their operational techniques are classified, but some nonfiction works and doctrinal manuals are available.
