Violent non-state actors at sea includes all violent non-state actors that engage in naval, amphibious or littoral violence or warfare.
These include:
Both Neptune's Navy and pirates are also examples of non-state actors whose role is a matter of perspective. Neptune's Navy believe themselves to be environmentalist, while the ICRW and the Japanese government have labeled them terrorists.[4] And pirates off the coast of Somalia claim to be "freedom fighters", defending Somali waters from pollution and foreign access.[3]
