This training circular (TC) is one of a series that describes an opposing force (OPFOR) for training U.S. Army
commanders, staffs, and units. See the References section for a list of other TCs in this series. (Other
publications in the former Field Manual [FM] 7-100 series will be converted to TCs as well.) Together, these
TCs outline OPFOR that can cover the entire spectrum capabilities of regular and/or irregular forces against
which the Army must train to ensure success in any future conflict.
