  COUNTERRECONNAISSANCE
  8-48. The OPFOR knows the significance of having reconnaissance forces on the
  battlefield to ensure mission success. For this reason, it heavily emphasizes the
  destruction of the enemy reconnaissance teams and dedicates numerous assets
  to accomplish this mission. The OPFOR includes either armed or lift helicopters
  in the counterreconnaissance plan to search for, locate, and report enemy
  reconnaissance teams. Depending on the plan, the OPFOR may use the armed
  helicopters, infantry, artillery, or other methods to destroy these teams.
  DIRECT AIR SUPPORT
  8-49. DAS is a mission to disrupt or destroy enemy forces in proximity to friendly
  forces. This mission can be accomplished using fixed-wing assets and fire support
  helicopters. Because these assets are centrally controlled, the missions are
  formulated at various staff levels and allocated based on assets available and
  significance of the mission. DAS missions are part of the fire support plan.
  INTERDICTION
  8-50. Air interdiction is planned and executed to destroy targets that are not
  in proximity to friendly troops. These missions are planned at the theater or
  OSC level to support the ground commander’s overall plan. Interdiction mis-
  sions can be conducted in advance of ground maneuver to set the conditions,
  or simultaneously to force the enemy to fight on different fronts.
  HELICOPTERS AS A MANEUVER FORCE
  8-51. As an exception to the rule, the OPFOR might employ a highly-trained
  unit equipped with modern attack helicopters as a maneuver force in the
  ground commander’s scheme of maneuver. In this role, the attack helicopter
  unit can be used as the fixing, assault, or exploitation force in the offense or
  as the disruption or counterattack force in the defense. In either offense or
  defense, it could be a deception force or reserve. Such employment is among
  the most complex missions conducted by aviation units and requires detailed
  planning, rehearsals, and execution.
  COMBAT SUPPORT AND COMBAT SERVICE SUPPORT MISSIONS
  8-52. Lift helicopters can support the ground commander in numerous
  combat support (CS) and combat service support (CSS) roles. For example,
  they can
  • Transport ground units conducting heliborne assaults.
  • Rapidly move forces on the battlefield.
  • Insert reconnaissance teams.
  • Conduct emergency resupply missions to isolated units.
  The aircraft can also be equipped as a gunship, minelayer, electronic jammer,
  or C2 platform.
  8-53. The OPFOR has a variety of medium- and heavy-lift helicopters that
  can provide transport capability throughout the battlefield. These aircraft are
  lightly armed and are used to move troops, equipment, and supplies in the
  relatively safe areas. Periodically, these aircraft are tasked to assist in CS
