  PART ONE
  HUMINT Support, Planning, and Management
  HUMINT collection activities include three general categories: screening,
  interrogation, and debriefing. In some cases these may be distinguished by legal
  distinctions between source categories such as between interrogation and
  debriefing. In others, the distinction is in the purpose of the questioning. Regardless
  of the type of activity, or goal of the collection effort, HUMINT collection operations
  must be characterized by effective support, planning, and management.

  Introduction
  INTELLIGENCE BATTLEFIELD OPERATING SYSTEM
  1-1. The Intelligence battlefield operating system (BOS) is one of seven
  operating systems⎯Intelligence, maneuver, fire support, air defense,
  mobility/countermobility/survivability, combat service support (CSS), and
  command and control⎯that enable commanders to build, employ, direct, and
  sustain combat power. The Intelligence BOS is a flexible force of Intelligence
  personnel, organizations, and equipment. Individually and collectively, these
  assets generate knowledge of and products portraying the enemy and the
  environmental features required by a command planning, preparing,
  executing, and assessing operations. Inherent within the Intelligence BOS is
  the capability to plan, direct, and synchronize intelligence, surveillance, and
  reconnaissance (ISR) operations; collect and process information; produce
  relevant intelligence; and disseminate intelligence and critical information in
  an understandable and presentable form to those who need it, when they
  need it. As one of the seven disciplines of the Intelligence BOS, HUMINT
  provides a capability to the supported commander in achieving information
  superiority on the battlefield.
  INTELLIGENCE PROCESS
  1-2. Intelligence operations consist of the functions that constitute the
  intelligence process: plan, prepare, collect, process, produce, and the
  common tasks of analyze, disseminate, and assess that occur throughout
  the intelligence process. Just as the activities of the operations process
  overlap and recur as circumstances demand, so do the functions of the
  intelligence process. Additionally, the analyze, disseminate, and assess tasks
