>Therefore, the concept of people's war was applied to the sea with fishermen and other nautical laborers being drafted into a maritime militia.
>Most vessels are issued with navigation and communication equipment while some are also issued small arms. The communications systems can be used both for communication and espionage. Often fishermen supply their own vessels, however, there are also core contingents of the maritime militia who operate vessels fitted out for militia work instead of fishing; these vessels feature reinforced bows for ramming and high powered water cannons. The increasing sophistication of militia vessels' communication equipment is a double-edged sword for Chinese authorities. New equipment, as well as training in its use, has substantially improved command, control, and coordination of militia units. However, the vessels' resulting professionalism and sophisticated maneuvers make them more identifiable as government-sponsored actors, dampening their ability to function as a gray-zone force.
