Title: Military intelligence Content: Military intelligence is information about an enemy or possible enemy. It is information that has first been interpreted and evaluated. It can include the terrain, the weather, and any other information about a theater of operations.Intelligence Theory: Key Questions and Debates, eds. Peter Gill, Stephen Marrin, Mark Phythian (Oxford; New York, Routledge, 2009), p. 27 Military intelligence gathering has a long history. == History == By the time of the Battle of Kadesh in BC Egyptian Pharaoh Ramses II was known to have had court spies.Terry Crowdy, The Enemy Within: A History of Spies, Spymasters and Espionage (Oxford; New York: Osprey, 2006), p. 15 In the biblical Book of Genesis Joseph thought his brothers were Canaanite spies. The Chinese general and strategist Sun Tzu (544 BC – 496 BC) wrote about the importance of military intelligence. In his book The Art of War he wrote: "If you know both yourself and your enemy you can win a hundred battles without jeopardy."The Politics Book, ed. Rob Colson (New York : DK Publishing, Inc., 2013), pp. 30–31 He emphasized the importance of using spies to learn an enemy's strength and what they were doing. He also wrote: "All warfare is based on deception".Karen McCreadie, Sun Tzu's The Art of War: A 52 Brilliant Ideas interpretation (Oxford : Infinite Ideas, 2006), p. 13 What he meant was war can even be avoided if you feed your enemy enough bad information. This is also called counterintelligence. Ancient Rome depended heavily on intelligence information to rule it's empire. When Major General Joseph Hooker took command of the Army of the Potomac he ordered Colonel George H. Sharpe to establish an intelligence unit. In 1863, they established the Bureau of Military Information.Jurgen Brauer; Hubert van Tuyll, Castles, Battles, and Bombs: How Economics Explains Military History (Chicago: University of Chicago Press, 2008), 166 The information they gathered was amazingly accurate. They calculated the size of the Confederate Army of Northern Virginia within 2% of the actual number. By war's end Sharpe knew more about the Army of Northern Virginia than many Confederate officers. One of the best sources of military information Sharpe's organization had was slaves who used the Underground Railroad to escape the South. During World War I intelligence became better organized. For the first time Airplanes were used for intelligence gathering.James L. Gilbert, World War I and the Origins of U.S. Military Intelligence (Lanham, MD: Scarecrow Press, 2012), p. vii An observer would fly with a pilot and diagram and map battlefields. They would also photograph intelligence targets and count troops. Operators at listening stations reported on enemy communications. == Climate == Before the 20th century accurate weather information was not available.Intelligence and Military Operations, ed. Michael Handel (Oxford: Cass, 2004), p. 88 Military planners had no data on the climate of their target area. In many cases they didn't even have accurate maps of the area. In 1941, when Nazi Germany invaded the Soviet Union they did not have any information on how harsh the Russian winters were. They did not have accurate maps of the roads. Between October 1941 and April 1942 the Germans lost between 100,000 and 112, 000 soldiers to frostbite. That is two-thirds of the number of soldiers who were killed in action or missing. == Terrain == General knowledge of terrain has always been important to military intelligence. But environmental factors sometimes went unnoticed. At the Battle of Agincourt mud was a major factor in the English victory. The extremely muddy ground slowed down the French and made them easy prey for English archers.George Alfred Henty, At Agincourt: A Tale of the White Hoods of Paris (New York: C. Scribner's, 1902), p. 324 In the 17th and 18th centuries army quartermasters, in addition to providing supplies, also scouted terrain and planned routes the army would take.David Kahn, 'The Rise of Intelligence', Foreign Affairs, Vol. 85, No. 5 (Sep. - Oct., 2006), p. 126 One of the first major improvements in gaining scientific knowledge of terrain was during the Russo-Japanese War (1904–1905). The Russians used geologists to do a detailed survey of Korea.Joseph S. C. Smith, 'Military Applications of Geology', Transactions of the Kansas Academy of Science, Vol. 67, No. 2 (Summer, 1964), p. 313 They also used geologists to advise them in building fortifications. Having little or no knowledge of terrain has proved costly to many battles in history. During the Pacific War in World War II, the United States forces had little knowledge of the terrain of the many Pacific islands they fought on. After the war, the United States Army Corps of Engineers contracted with the United States Geological Survey to provide detailed geological information on occupied islands.Gilbert Corwin, 'Engineer intelligence and the Pacific geologic mapping program', Military Geology in War and Peace, eds. James R. Underwood; Peter L. Guth (Boulder, CO: Geological Society of America, 1998), p. 67 == Modern military intelligence == In addition to intelligence gathering on other countries, terrorism is also a major concern of military intelligence.Martin, C. Augustus (ed) 2011. The SAGE Encyclopedia of Terrorism. 2nd ed, Thousand Oaks: SAGE, p. 277. Intelligence gathering by examining communications signals has been a regular activity of military intelligence. Since 2005 military and other intelligence services have also monitored the Internet. In some 21st century countries, military intelligence competes with civilian-led intelligence agencies.Peter Jackson & L.V. Scott (eds) 2004. Understanding Intelligence in the Twenty-First Century: Journeys in Shadows. London; New York: Routledge, p. 148 Often military and civilian intelligence gathering have different goals and objectives. Both gather their own intelligence and do not always share information. New methods of intelligence gathering, such as video imagery, satellites, reconnaissance aircraft and drones, produce tremendous amounts of raw data. Artificial intelligence is used to analyze this data for information.Keith Frankish, William M. Ramsey (eds) 2014. The Cambridge Handbook of Artificial Intelligence. Cambridge: Cambridge University Press, p. 26
