A clandestine cell system is a method for organizing a group of people (such as resistance fighters, sleeper agents, mobsters, or terrorists) such that such people can more effectively resist penetration by an opposing organization (such as law enforcement or military units). 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.
