Robert Clark not only explains specific collection systems for analysts, but helps collectors work across boundaries and stovepipes, encouraging them to share collection approaches and to promote cross-pollination of ideas across the collection disciplines. The first part of the book covers open source (OSINT), human intelligence (HUMINT), communications intelligence (COMINT), and cyber collection , while the second part of the book is concerned with signals intelligence (SIGINT), imagery intelligence (IMINT), and others. There is also a chapter devoted to the management of intelligence collection. This full-colour guide is richly illustrated with images and graphics that help readers see examples of each type of collection material.
