Tactics of terrorism
Suicide terrorism is the most aggressive form of terrorism, pursuing coercion even at the expense of losing support among terrorists' own community. What distinguishes a suicide terrorist is that the attacker does not expect to survive a mission and often employs a method of attack that requires the attacker's death in order to succeed (such as planting a car bomb, wearing a suicide vest, or ramming an airplane into a building). In essence, a suicide terrorist kills others at the same time that he kills himself. Usually these tactics are used for a demonstrative purposes or to targeted assassinations. In most cases though, they target to kill a large number of people. Thus, while coercion is an element in all terrorism, coercion is the paramount objective of suicide terrorism.
Definitions of terrorism
A 2003 study by Jeffrey Record for the United States Army quoted a source (Schmid and Jongman 1988) that counted 109 definitions of terrorism that covered a total of 22 different definitional elements. Record continued "Terrorism expert Walter Laqueur also has counted over 100 definitions and concludes that the 'only general characteristic generally agreed upon is that terrorism involves violence and the threat of violence.' Yet terrorism is hardly the only enterprise involving violence and the threat of violence. So does war, coercive diplomacy, and bar room brawls".
