Violent non-state actors engage in combat in all
terrains. Common and influential types of VNSAs include: • Criminal organizations (
drug cartels, for example) may carry out assassinations, kidnappings, thefts, extortions; operate protection rackets; and
defend their turf from rival groups and the military. •
People's movements or sections of them that have chosen
guerrilla tactics (also known as
asymmetric warfare) to pursue their aims. An example is the
Naxalite-Maoist insurgency in central India. •
Pirates, outlaws that rob ships or take hostages in order to get a ransom. Recent examples include
piracy off the coast of Somalia. Some pirates also state that they serve as "coastguards" in place of a
failed state. •
Private military companies, and corporations that either have their own, or hire, private military services. An example is
floating armouries in the Indian Ocean. Private military companies are also active in counter-piracy, and thus provide an example of violent non-state actors combating other violent non-state actors. •
Violent non-state actors at sea. Both pirates and private military companies are also part of this group, along other less malicious actors, such as
Neptune's Navy. • Religious or ideological groups, such as
Boko Haram in and around Nigeria, that espouse armed violence as a moral or sacred duty. • Citizen militia, which may form to protect a locality from (or threaten it with) attack, such as the
anti-balaka movement in the Central African Republic. •
Paramilitary groups, which make use of military methods and structures to pursue their agenda, such as the now-decommissioned
Provisional Irish Republican Army. •
Warlords, who are leaders using armed violence to exercise military, economic, and political control over territory within a sovereign state. Warlords have a long history in Afghanistan, for example. Phil Williams, in an overview article, identifies five types of VNSAs: •
Warlords •
Militias •
Insurgents •
Terrorist organizations •
