clandestine cell

A clandestine cell system is a method for organizing a group of people, such as resistance fighters, sleeper agents, mobsters, or terrorists, to make it harder for the police or military to catch them. In a cell structure, each of the small groups of people in the cell know the identities of the people only in their own cell. Thus any cell member who is apprehended and interrogated (or who is a mole) will not likely know the identities of the higher-ranking individuals in the organization. The structure of a clandestine cell system can range from a strict hierarchy to an extremely distributed organization, depending on the group's ideology, its operational area, the communications technologies available, and the nature of the mission. Criminal organizations, undercover operations, and unconventional warfare units led by special forces may also use this sort of organizational structure. Covert operations vs. clandestine operations Covert and clandestine operations are not the same when it comes to tradecraft. The modern NATO definition of a covert operation says the identity of the sponsor is concealed, but in a clandestine operation the operation itself is concealed from the participants. Put differently, clandestine means "hidden", and covert means "deniable"—that is to say that the sponsor of a covert action is sufficiently removed from it that the sponsor can claim ignorance in the event the plot is discovered.
