Seller's Description:
Very good. Pencil ersasure residue on first page. 109 p. Includes illustrations. In the early morning of February 27, 1991, during the Persian Gulf War, Army Corporal Douglas Lance Fielder was unintentionally killed by U. S. soldiers who had mistaken him and his fellow engineers as the enemy. GAo was requested to determine the events that had led to the fratricide, assess the adequacy of U.S. Army investigations following that fratricide, and investigate allegations that Army officials hindered invistigations of the fratricide incident or influenced their outcome. From Wikipedia: "Fratricide (from the Latin words frater "brother" and cida "killer, " or cidum "a killing, " both from caedere "to kill, to cut down") is the act of a person killing his or her brother....Fratricide may also be used to refer to friendly fire incidents. It also refers to the possible destruction of one MIRV warhead by another. Targets may be arranged deliberately to increase the likelihood in a strategy called dense pack." Also from Wikipedia: "The Gulf War (2 August 1990 28 February 1991), codenamed Operation Desert Storm (17 January 1991 28 February 1991) was a war waged by a U.N. -authorized Coalition force from 34 nations led by the United States, against Iraq in response to Iraq's invasion and annexation of Kuwait. The war is also known under other names, such as the Persian Gulf War, First Gulf War, Gulf War I, or the First Iraq War, before the term "Iraq War" became identified instead with the 2003 Iraq War (also referred to in the U.S. as "Operation Iraqi Freedom"). Kuwait's invasion by Iraqi troops that began 2 August 1990 was met with international condemnation, and brought immediate economic sanctions against Iraq by members of the U.N. Security Council. U.S. President George H. W. Bush deployed U.S. forces into Saudi Arabia, and urged other countries to send their own forces to the scene. An array of nations joined the Coalition. The great majority of the Coalition's military forces were from the U.S., with Saudi Arabia, the United Kingdom and Egypt as leading contributors, in that order. Saudi Arabia paid around US$36 billion of the US$60 billion cost. The war was marked by the beginning of live news on the front lines of the fight, with the primacy of the U.S. network CNN. The war has also earned the nickname Video Game War after the daily broadcast images on board the U.S. bombers during Operation Desert Storm. The initial conflict to expel Iraqi troops from Kuwait began with an aerial bombardment on 17 January 1991. This was followed by a ground assault on 24 February. This was a decisive victory for the Coalition forces, who liberated Kuwait and advanced into Iraqi territory. The Coalition ceased their advance, and declared a cease-fire 100 hours after the ground campaign started. Aerial and ground combat was confined to Iraq, Kuwait, and areas on Saudi Arabia's border. Iraq launched Scud missiles against Coalition military targets in Saudi Arabia and against Israel."
