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.
Subversion
Offensive terror can be defined as the killing of people, destruction of property, kidnapping, etc. It is usually a minor part of subversion and, "is used not to exert force in the transfer of state power, but is meant to cower the people or ruler". Force used in this manner is meant to reinforce other forms or persuasion in addition to cowering the people or leaders. Additionally, much like civil unrest and agitation, it raises the question of whether or not the state can provide security for the population. Terror also provides a practical motivation of physically removing political opponents. The assassination of an organization's leader may open the door to a successor that is more friendly to the subversives position or possibly someone that has successfully infiltrated the organization and is in fact one of the subversives.
