A report on the Symposium on Counterinsurgency held at RAND’s Washington Office during the week of 16 April 1962. Its purpose was to bring together those with first-hand experience of counterinsurgency for discussions that might lead to fresh insights and a detailed body of expert knowledge. This new release of this important report, which includes a new foreword by Stephen T. Hosmer, remains relevant to present-day counterinsurgency operations.
