For definitions of other key terms, the reader should refer to the index, fn page numbers in bold type indicate the main entry for a particular topic. First, the armor- and mechanized-based and infantry-based OPFOR modules are not simply unclassified handbooks on the armed forces of a particular nation.

OPFOR military art relies on extensive engineer support at every level. Armor- and mechanized-based forces are the norm throughout the industrialized world.

Crossing is also a generic term identifying the site of a river crossing or the act of crossing. Field Manual depicts infantry-based forces of fn country that is divided geographically into an unspecified number of military regions, each with a number of subordinate military fmm. They normally conduct set-piece operations, integrating arms at the tactical level.

Engineers prepare obstacle plans in advance and closely tie them in with the fire engagement plan system of fires.

In 10-61 attack and in meeting engagements or battles, obstacles fn flanks, disrupt counterattacks, and strengthen captured positions.

If the OPFOR assumes a defense out of contact with the enemy, support can begin with the creation of defensive works and the improvement of routes for the formation to deploy. The proliferation of such foreign systems or technologies could pose a threat to the U. These may be the forces of a preindustrial nation or a nonnation group.


Even multiple army groups may come under a series of theater headquarters that orchestrate complex, large-scale operations. This may be an important consideration when supplies are limited. The name of that country is the State.

Minefield breaching during the offense is generally the responsibility of the combined arms unit. During the offensive, the primary engineer reconnaissance mission is to obtain more precise information on The forcing of medium rivers 60 to m wide is an army task using the army’s organic and attached means.

The OPFOR identifies two methods of overcoming water obstacles–crossing when not expecting enemy contact and forcing when expecting enemy contact.

They may also have high-technology communications and reconnaissance means. However, when faced with a large, technologically advanced army, it may choose to redefine the terms of conflict and pursue its aims through terrorism, insurgency, or partisan warfare.

In the defense, engineer elements observe enemy preparations for the attack and determine the character and extent of enemy engineer activity. Fortification preparation combines and uses to best advantage 100-611 terrain’s protective properties, local construction materials, and engineer excavation equipment.

Even with a small infantry-based force, however, the State might mobilize and deploy one army- or corps-size force capable of conducting large-scale operations against a neighboring country whose armed forces are also infantry-based. This introduction provides definitions of some basic terms used throughout the manual.

FM is a training tool that trainers and OPFOR organizations must use with flexibility to meet their training requirements. However, their primary responsibility is to support and ensure the mobility of operational formations. The OPFOR continues to develop methods of remote minelaying including delivery by minelaying helicopters, fixed-wing aircraft, tube artillery, rockets, or missiles.

Other engineer tasks in the defense are clearing obstacles, crossing gaps, and eliminating the effects of fire strikes.

Large infantry-based forces can have multiple armies or corps and conduct extensive set-piece operations over broad frontages. Therefore, mechanical and remote means have recently become more prevalent. The OPFOR 100–61 at night for concealment, although preparing dummy positions must proceed during daylight hours.


When opposed by an adversary of similar capabilities, an infantry-based OPFOR 1000-61 conduct conventional, force-oriented combat. The MSD mission includes Such an OPFOR should portray the specified, real-world threat force with the greatest possible fidelity based on the best available classified and unclassified information. The high-technology end of the armor- and mechanized-based OPFOR approaches the level termed complex, adaptive forces.

This series provides a flexible OPFOR package that users can tailor to represent a wide range of potential threat capabilities and organizations.

FM provides the trainer with a military doctrine and operational art for the armor- and mechanized-based OPFOR. If so, the OPFOR can take much longer to carefully bury and camouflage 1000-61 mines and integrate the minefields into the total defensive scheme.

If a forcing from the march does not succeed, the OPFOR could mount a further effort with brief, or even detailed, preparation.

An MSD’s composition depends on the mission, terrain, time and equipment available, and the enemy. It usually 10-61 of a reconnaissance and obstacle-clearing group, one or two road and bridge construction and repair groups, and a route-marking group. The same types of minefield may also support a less than fully prepared defensive position.

When the OPFOR is on the defensive, engineer reconnaissance elements reconnoiter terrain and the enemy situation to determine routes best suited for a return to offensive action.
