Stefan Leader characterizes these groups, namely ELF, with having "leaderless resistance" which he describes as "a technique by which terrorist groups can carry out violent acts while reducing the risk of infiltration by law enforcement elements. The basic principle of leaderless resistance is that there is no centralized authority or chain-of-command." Essentially this consists of independent cells which operate autonomously, sharing goals, but having no central leaders or formal organizational structure. Those who wish to join are typically encouraged to start their own cell, rather than seek out other members and jeopardize their secrecy.
