This manual is one of a series that describes a capabilities-based Opposing Force (OPFOR) for training US Army commanders, staffs, and units. The manuals in this series are--

  • FM 100-60. Armor- and Mechanized-Based Opposing Force: Organization Guide.

  • FM 100-61. Armor- and Mechanized-Based Opposing Force: Operational Art.

  • FM 100-62. Armor- and Mechanized-Based Opposing Force: Tactics.

  • FM 100-63. Infantry-Based Opposing Force: Organization Guide.

  • FM 100-64. Infantry-Based Opposing Force: Operations and Tactics.

  • FM 100-65. Opposing Force Equipment Guide.

  • FM 100-66. Opposing Force in Operations Other Than War.

    Together, these manuals outline an OPFOR that can cover the entire spectrum of military capabilities against which the Army must train to ensure success in any future conflict.

    Applications of this series of manuals include field training, training simulations, and classroom instruction throughout the Army. All Army training venues should use an OPFOR based on these manuals, except when mission rehearsal or contingency training requires maximum fidelity to a specific country-based threat. Even in the latter case, trainers should use appropriate parts of this capabilities-based OPFOR to fill information gaps in a manner consistent with what they do know about a specific threat.

    This manual provides a menu of possible organizational building blocks for an infantry-based OPFOR. From this menu, users can build an order of battle appropriate to their training requirements. For each type of unit, the manual outlines basic unit structure and possibly a number of variations. For most units, the manual also lists principal items of equipment. Appendixes provide guidance and examples for users who wish to substitute other items of equipment for the baseline systems listed for a unit.
