text: Movement and Forms of Maneuver
  infiltration purposely maneuvers units out of sustainment range for longer periods to surprise the enemy. The
  prolonged time away from medical evacuation, maintenance, and resupply of classes of supply increases the
  risk to the infiltrating unit, which requires detailed planning to mitigate. After identifying gaps or weaknesses
  in the enemy force’s defensive positions, units assign infiltration lanes, contact points, and objectives to
  subordinate units. These objectives afford the infiltrating force positions of advantage over enemy forces (the
  objectives are not required to be to the rear of the enemy force). Each subordinate unit picks one or more
  routes within the assigned lane and establishes additional contact points, rally points, assault points, and other
  control measures as required.
  2-92. Units require routes within an infiltration lane to be far enough apart to prevent an infiltrating element
  on one route from seeing other infiltrating elements, but close enough so that an infiltrating element could
  switch quickly to another route if the situation requires it. They may use single or multiple infiltration lanes
  depending on the infiltrating force’s size, the amount of detailed information on enemy dispositions, terrain,
  time allowed, and number of lanes available. Units require each route to provide infiltrating elements cover
  and concealment while avoiding known enemy and civilian locations and movement routes as much as
  possible. If possible, the subordinate unit selects the exact routes during the preparation phase after
  reconnoitering each infiltration lane. That subordinate decides whether the unit infiltrates as a whole or as
  smaller elements, depending on the enemy force’s density and strength.
  2-93. A single infiltration lane—
  * Facilitates navigation, control, and reassembly.
  * Requires the existence or creation of only one gap in the enemy force’s position.
  * Reduces the area for which detailed intelligence is required.
  2-94. Multiple infiltration lanes—
  * Require the existence or creation of more gaps in the enemy force’s security area.
  * Reduce the possibility of compromising the entire force.
  * Increase difficulty with maintaining control.
  2-95. The sizes and numbers of infiltrating elements are major considerations for units when deciding
  whether to use a single lane or multiple infiltration lanes. If the infiltration takes place using multiple
  elements, contingency plans must address the following situations:
  * A lead element, possibly the security force, makes contact, but the trail elements have not started
  infiltrating.
  * A lead element infiltrates successfully but compromises one or more trailing elements.
  * A linkup point is compromised.
  * An element is isolated by the enemy.
  2-96. The infiltration plan also addresses the following considerations:
  * Availability of supporting fires throughout the operation.
  * Linkup or extraction of the infiltrating unit after mission completion.
  * Sustainment of the infiltrating force during the operation, including casualty evacuation.
  * Tactical deception operations.
  * Linkup of various infiltrating elements.
  * Command and control of forces.
  * Positioning of combat vehicles to support the infiltrating elements.
  * Use of limited visibility and rough terrain to mask movement and reduce possible detection.
  * Infiltration of the largest elements possible to maintain speed and control.
  * Rehearsals.
  * Abort criteria.
  * Critical friendly zones.
  2-97. Planned recognition signals and linkup procedures for the infiltration should be simple and quick. If
  there have not been any firing or other noises, users of signals should consider the probability of detection.
  However, if there have already been assaults, artillery, and small arms fire, stealth is less of a concern. A lack
