A clandestine cell structure is a method for organizing a group of people like resistance fighters or terrorists in such a way that it can more effectively resist penetration by an opposing organization (such as a law enforcement organization). In a cell structure, each small group of people in the cell know the identities of only the people in their cell. Thus, a cell member who is apprehended and interrogated will not know the identities of the higher-ranking individuals in the organization. Depending on the group's philosophy, its operational area, the communications technologies available and the nature of the mission, it can range from a strict hierarchy to an extremely distributed organization.
