text: FOREWORD
  In today’s complicated and uncertain world, it is impossible to predict the exact nature of
  future conflict that might involve the U.S. Army. So the Army must be ready to meet the
  challenges of any type of conflict, in all kinds of places, and against all kinds of threats. This is
  the nature of the contemporary operational environment (COE), and training for such an
  environment requires a different type of Opposing Force (OPFOR) than that of the past.
  The Deputy Chief of Staff for Intelligence (DCSINT) of the U.S. Army Training and Doctrine
  Command (TRADOC) is the Executive Agent for the development, management,
  administration, integration, and approval functions of the OPFOR Program across the Army.
  Thus, the TRADOC DCSINT is responsible for documenting the doctrine, organization, and
  capabilities of a contemporary OPFOR that is appropriate for training the Army’s leaders,
  soldiers, and units for the COE.
  In the FM 7-100 series, the TRADOC Office of the Deputy Chief of Staff for Intelligence
  (ODCSINT) has created a flexible baseline for an OPFOR that can be adapted to meet a
  variety of different training requirements in a number of different scenarios that reflect the
  COE. The OPFOR operational doctrine outlined in FM 7-100.1 represents a realistic
  composite of potential adversaries the Army might encounter in the real-world situations of
  the foreseeable future. However, the world is continually changing, as are the threats and
  challenges for which the Army must be prepared. The Army must remain flexible, as must the
  OPFOR designed to serve as a challenging sparring partner in the training environment.
  This manual is approved for use in all Army training venues. However, as the contemporary
  OPFOR and other aspects of the COE are integrated into Army training, the TRADOC
  ODCSINT and the intelligence community will continue research and analysis of real-world
  developments and trends. The goal of this continued effort is to keep our OPFOR and our
  understanding of the COE truly contemporary and relevant as the world around us
  changes. Thus, this manual is intended to be a living document, and the ODCSINT will
  modify and change it as often as necessary in order to ensure its continued relevance in
  light of changes and developments in the COE. In anticipation of such changes, this manual
  will be published primarily in electronic format with only limited distribution of hard-copy,
  printed manuals. The electronic version is available on the Army Knowledge Online (AKO) at
  http://www.us.army.mil and the General Dennis J. Reimer Training and Doctrine Digital
  Library (ADTDL) at http://www.adtdl.army.mil. Users also need to monitor the TRADOC
  ADCSINT-Threats Knowledge Center on AKO for information regarding periodic updates.
