This strategy mimics the use of strategic hamlets, regroupment centers, and so-called protected villages during civil wars in Burundi, Indonesia, the Philippines, Peru, Rwanda, Uganda, and Vietnam, where government forces ordered people living in conflict areas to relocate to particular locations. In addition to denying rebels access to the population, these methods were used to help counterinsurgents distinguish friend from foe while fighting shadowy guerrillas who hid among civilians. Areas outside relocation sites were transformed into free-fire zones where those remaining were assumed to be rebel fighters or supporters. The sites themselves served as instruments of identification. Occupants were screened and catalogued—making the population more “legible” to the state—and their movements were used as continuous indicators of their political loyalties.
