Abstract
This chapter explains the terrorism of insurgents and rebels. Despite the magnitude of transnational terror attacks, most acts of terrorism around the globe are actually perpetrated by assailants that reside in the same country they target. Rebel organizations primarily use violence against civilians to help them achieve their war aims. These can be either political or social. Asymmetric insurgencies or guerrilla wars often use terror to keep members active, civil compliance, maintain territorial control, and demonstrate a state's inability to govern. Violent actors make strategic decisions about the types of violence they utilize during conflicts.
