  Movement to Objective
  13-31. Speed and security are the primary concerns during movement to the
  objective. If the landing force is moving at night, it can use established road
  networks to reach the objective before dawn. If movement is during the day,
  the unit moves cross-country using terrain features to provide concealment
  when possible. During movement, the landing force maintains radio silence
  until making contact with the enemy, with only the landing force commander
  transmitting messages.
  13-32. Since the information received before departure is perishable,
  reconnaissance missions during the ground movement phase are ex-
  tremely important. For airborne forces, these missions are performed by
  reconnaissance teams from the brigade and/or battalion level. These teams
  may have engineer or chemical defense personnel attached.
  13-33. Rapid execution is especially important to the heliborne force. The force
  departs the assembly area with reconnaissance in the lead and on the flanks.
  The landing force attacks the target as quickly as possible in order to gain
  surprise and maintain momentum.
  Offense
  13-34. Once on the ground, offensive tactics of airborne forces are similar to
  those of similarly equipped infantry forces. Before the attack, the airborne
  force deploys its fire support units to provide maximum support. Airborne
  forces at the final objective attack to destroy the enemy or to seize control of
  the enemy-held area or facility. A heliborne force can be augmented with
  combat engineers, antitank weapons, artillery, and chemical defense troops.
  The force usually attempts to attack its objective from several directions at
  once. A heliborne force is generally assigned an objective less heavily defended
  than that assigned to an airborne force.
  Defense
  13-35. Once the landing force has seized an objective, it must defend that
  objective until the arrival of friendly ground maneuver forces. Usually, the
  landing force establishes a perimeter defense. In some cases, the terrain and
  the enemy’s situation may permit establishing a defense in depth, with a
  small, mobile reserve. A number of factors influence the capability to remain
  on the objective: days of supply on hand, a secure air resupply corridor, the
  availability of air support, and the enemy’s ability to respond to the landing.
  Heliborne forces, especially those drawn from the regular ground forces, have
  little sustainability, and their ability to remain on the objective is limited.
  Linkup with a ground maneuver force should occur as quickly as possible.
  Linkup
  13-36. Airborne or heliborne units either await a linkup with friendly forces
  or, when necessary, fight their way back to friendly lines. The rule of thumb is
  that the probability of overall success is greater the sooner the linkup occurs.
  To accomplish linkup, the unit sends a reconnaissance patrol to meet the
  approaching ground maneuver force units. The reconnaissance patrol provides
  information on the best approaches into the area, the security situation on the
